Young Collection on Agent Orange comprises 120 linear feet and spans the late 1800s to 2005; however, the bulk of the coverage is from the 1960s to the 1980s and there are many undated items. The collection was donated to Special Collections of the National Agricultural Library in 1985 by Dr. Alvin L. Young (1942- ). Dr. Young developed the collection as he conducted extensive research on the military defoliant Agent Orange. The collection is in good condition and includes letters, memoranda, books, reports, press releases, journal and newspaper clippings, field logs and notebooks, newsletters, maps, booklets and pamphlets, photographs, memorabilia, and audiotapes of an interview with Dr. Young.&lt;/p&gt;&#13;

Dr. Young developed the collection as he conducted extensive research on the military defoliant Agent Orange.

�Determination of Tetrachlorodibenzo-p-dioxin (TCDD) in Human Adipose
Tissue
RJRPOSE: The Veterans Administration has undertaken a study to ascertain
whether TCDD can be detected and measured in the body fat of human
volunteers who believe that they were exposed to the defoliant Orange in
Viet Nam and in the fat of other volunteers who have had no known contact
with Orange. Some lots of the defoliant contain small amounts of TCDD
as a contaminant.
BACKGROUND: A wide variety of late adverse effects have been said to
occur years after exposure to the defoliant mixture called "Orange." In
most cases involving Vietnam veterans it is difficult or impossible to
document an individual's exposure to the defoliant mixture and it is
rarely, if ever, possible to determine whether a person was exposed to
the contaminant TCDD which varies in an undetermined manner from lot to
lot. This contaminant is the most toxic constituent of the defoliant as
judged by its acute toxicity in various animal species.
The body concentrates in its adipose tissue any TCDD it retains and some
lower animals are known to retain it there for considerable periods. It
has been suggested that individuals may sequester TCDD in their body fat
and release it in toxic quantities when fat is suddenly decreased in
amount even years later.
One individual who had been intensively exposed to TCDD in an industrial
accident was found to have 0.04 to 1.04 parts per billion of thesubstance
in varius organs and 1.84 parts per billion in body fat at autopsy
several months after exposure. (Peggiani, reported at the 20th Congress
of the European Society of Toxicology, June 25-28, 1978) It is unlikely
that such high concentrations would persist in individuals exposed less
intensively ten or more years earlier in Viet Nam. Since assay methods
are being developed to identify and measure TCDD at concentrations of a
few parts per trillion, the VA decided to determine whether such an
experimental assay could detect the compound in human, adipose tissue long
after possible exposure.
Although the test was to be conducted on Viet Nam veterans who attribute
adverse effects to their prior exposure, it was recognized that discovery
of TCDD in their body fat could not prove that any defect, disease or
disability is caused by the substance. Since TCDD occurs in defoliants
or herbicides that have been used since the Viet Nam conflict, its
presence in the fat of any one individual would not even prove
conclusively that exposure occurred in Viet Nam. Detection of TCDD in
his fat, would indicate only that a man had prior contact with the
substance.
Relatively large samples of body fat would increase the likelihood of
finding very low concentrations and the experimental nature of the assay
techniques made adequate samples even more desirable. For these reasons,
surgeons obtained the fat samples by biopsy.

�METHODS: Fat Samples. Twenty Vietnam veterans who had conditions that
they considered due to exposure to the defoliant Orange volunteered to
have an open biopsy of subcutaneous adipose tissue from the anterior
abdominal wall. Three Air Force officers who had repeated and relatively
recent documented contact with Orange also volunteered. Eleven "control"
veterans without known exposure had samples of subcutaneous fat removed
during operations performed for other reasons, including herniorrhaphy,
ureterolithotcmy, and abdomino-peritoneal resection of a rectal adenocarcinoma. This control group matched the exposed group in age range, sex
and general geographic location. All volunteers, both "control" and
exposed, gave written informed consent.
The fat removed at biopsy weighted 3.8 grams or more except for one
control sample of 1.4 grams; most specimens weighed 7 grams or more.
Samples were placed in corked glass containers that had been rinsed with
reagent grade acetone to remove interfering substances. The tissue was
promptly chilled and kept refrigerated until assayed.
The assays, including the sample extraction, were performed by Michael L.
Gross, Ph.D., at the Midwest Center for Mass Spectrometry. The National
Science Foundation supports this Center.
Sample Extraction. In the assay laboratory, a 1 to 10 gram portion of
the fat specimen was weighed and spiked with a known amount of TCDD
containing non-radioactive but unnatural ^'Cl that the assay can
distinguish from the natural compound. The sample was completely
hydrolyzed by saponification in 15 ml of ethanol and 30 ml of 40% aqueous
KOH in a reflux apparatus for 60 minutes without stirring. All solvents
were of the highest grade and suitable for residue analysis.
The solution, diluted with 20 ml of ethanol and 40 ml of water, was
extracted four times with nanograde hexane. The first extraction was
with 25 ml of hexane, using vigorous shaking for one minute. The aqueous
layers was separated and extracted three more times with 15 ml of hexane.
The four hexane extracts were combined and washed with 10 ml of water to
remove excess base followed by washes with 10 ml of concentrated sulfuric
acid repeated four times or until both layers were clear. After a final
washing with 10 ml of water, the hexane layer was concentrated to
approximately 1 ml under a stream of dry nitrogen.
The first of three chronatography steps used unactivated silica gel as a
5 cm column in a disposable pipet plugged with glass wool. The silica
was capped with 0.25 cm of anhydrous sodium sulfate to remove water and
was wetted with hexane before the sample, dissolved in 1 ml of hexane was
transferred to the column. The sample container was rinsed with a second
milliliter that was subsequently added to the column. Dioxin was eluted
with 3 ml of 20% (V/V) benzene in hexane and the eluate concentrated to 1
ml.
A second chromatography used alumina that had been washed by saturating
it with methylene chloride and activated at 225° C for 24 hours. A

�column, prepared as was the silica column, was stored at room temperature
in a desiccater until used. After the column was wetted with hexane, the
sample and a 1 ml hexane rinse of its container were transferred to the
column. The alumina was eluted with two 3 ml portions of pesticide grade
carbon tetrachloride, then with 4 ml of nethylene chloride. These
solvents were all used to rinse the container of the first-step eluate
before being transferred to the alumina column. The separated nethylene
chloride fraction was concentrated under nitrogen as the volatile solvent
was replaced with hexane. All other fractions were discarded.
The final chromatography used florisil that had been saturated with
methylene chloride, activated at 165° C for 24 hours, and cooled in a
vacuum desiccator. A 5 cm column in a disposable pipet plugged with
glass wool was packed with 10 ml of hexane under light nitrogen pressure
to remove air pockets. The sample, dissolved in 1 ml of hexane, was
added to the column and its container rinsed with 1 ml of 8% (by volume)
of methylene chloride in hexane. The column was eluted with 9 ml of the
latter solvent mixture to remove 80-85% of the contaminating PCBs. A
final elution with 8 ml of methylene chloride contained the TCDD and was
collected in a centrifuge tube from which the solvent was evaporated to a
small volume under a stream of dry nitrogen. The sides of the centrifuge
tube were rinsed down with 1 ml of hexane and the volume was again
reduced. After a final rinsing with 1 ml of hexane, the solvent was
evaporated to a volume less than 100 microliters, the tube was closed
with a teflon-lined screw cape and stored at -20° C.
Gas Chromatography/Hic|h Resolution Mass Spectrometry (GC/HBMS) Analysis.
At the time of analysis, the sides ""of the centrifuge tube were washed
thoroughly with approximately 100 microliters of hexane or isooctane
using a graduated syringe. The solvent was allowed to evaporate during
the washing until about 50 microliters remained and this volume was
accurately measured. Three-fourths of the solution was replaced in the
tube and the fourth remaining in the syringe was used for the initial
analysis.
Gas chromatography employed a Perkin-Elner Sigma II gas liquid
chromatograph with a 6 foot by 1/4 inch O.D. glass column containing a
Dow mixed phase packing. Typically it was operated at a helium flow rate
of 15 cc per minute with the injector at 270&lt;£. The column temperature
was programmed for 1.5 minutes at 250° and then ramped at 10° C per
minute to 300° C where it remained until the dioxin had eluted. The
GC/HEMS interface was a direct coupling via a simple glass-lined
stainless steel capillary held at an average temperature of 250° C. The
typical retention time was 3.4 minutes with a peak width at 10% height of
approximately 40 seconds.
The Kratos MS-5076 ultra high resolution mass spectrometer employed has
an ultimate resolution equal to 180,000; it was tuned to a resolving
power of 10,000 giving a 10% valley definition. The electron impact
source was set at 70 eV ionizing energy and an accelerating voltage of
8 K7. The source was at 260° C. Data were acquired using the standard
ion switching feature of the MS-50, i.e. dual ion monitoring.

�The first analysis was made monitoring one channel, m/z 321.8936, for the
most abundant molecular ion of TCDD having natural isotopic elemental
abundances. The second channel, m/z 327.8848, detected -^d^-TCDD, the
internal standard. The complete peak profiles were acquired at a band
width of 3000 Hz by scanning at a frequency of about 2 HZ, corresponding
in each case to a mass range of 300 parts per million (0.096 amu). Ihe
output of the spectrometer was accumulated over about 75 sweeps per
channel using a Nicolet Model 1170 signal analyzer. The resulting
signals were submitted to a three-point smoothing routine prior to being
printed on an X-Y recorder.
Results were calculated by the internal standard "ratio method" in3which
standard samples containing known amounts of natural TCDD and the ' Cl
internal standard were analyzed throughout the testing period. A
calibration curve was then prepared by plotting the ratio of the known
weights of TCDD and internal standard against the ratio of signal
intensities, i.e. intensity at m/z 321.8936 vs. intensity at m/z
327.8848. The content of TCDD in a test fat sample was calculated from
the ratio of signal intensities at the two m/z values, reading the TCDD
concentration from the calibration plot. The detection limit in the fat
samples was obtained by multiplying the noise level by 2.5, considered to
be the maximal amount of TCDD that could be present. The per cent
recovery was measured using the absolute signal intensity for the
internal standard and mass spectrometer response factors measured by
analyzing standard solutions of the internal standard.
The second or validation analysis was performed by injecting a second
aliquot from the graduated syringe into the GC/HBMS for any fat sample
that showed detectable concentration of TCDD on the first analysis. For
validation, the high mass channel was centered at 321.8936 and the low
mass channel at 319.8965 for the second most abundant molecular ion of
TCDD. All other conditions were as for the first analysis. The theoretic
ratio of intensities, m/z 319.8965: m/z 321.8936, is 0.77.
The TCDD concentration in the validation sample was calculated based on
the absolute signal intensity observed at m/z 321.8936, using response
factors determined for the mass spectrometer by analysis of standard
TCDD solutions. Based on the measured per cent recovery, the
quantitation was adjusted to 100% recovery. The validation was
considered acceptable if the observed ratio of signals was 9.77+ 0.10.
RESULTS: All 34 fat samples have been analyzed and validated; the
results are presented in Table I. Table II summarizes the data from
Table I and discriminates between individuals who reported symptoms they
felt were related to Orange exposure and those who reported no related
symptoms.
The amount of TCDD ranged from none to 89 parts per trillion in the group
of 23 persons reporting exposure to Orange, Six of 20 veterans (Codes
10, 12, 15, 25, 27 and 28) who reported exposure to defoliants in Viet

�Nam had concentration of TCDD that were greater than 2 parts per trillion
above the detection limit. One such veteran had a sample that yielded
equivocal results (Code 29) but has been included in Table II among those
with a definite elevation. When the difference between concentration and
detection limits is less than 3 parts per trillion (see Table I) assays
results are questionable.
Atong the 11 veterans, "controls", reporting no exposure to defoliants
only one (Code 3) had a concentration of TCDD high enough to be accepted
as certain. Three Air Force officers are shown separately in Table I.
Although all had handled defoliants and TCDD within months of the biopsy
and had been heavily exposed to Orange for years before that, none
complained of symptoms despite levels above the certainty limits.
The 20 veterans reporting exposure all were selected as believing they
had symptoms related to dioxin. None of the "controls" attributed ill
effects to TCDD since none had known exposure to it. The assayed groups
do not include an equally large group who were exposed to TCDD but have
remained asymptomatic; the Air Force officers have these characteristics,
however.
DISCUSSION AND CONCLUSIONS: The results demonstrate that GC/HEMS
analysis can detect and measure very small amounts of tetrachlorcx3ibenzo-p-dioxin (TCDD) in human adipose tissue even long after the
last known exposure. This makes available a research assay method that
is rather unattractive because it requires surgical biopsy to obtain a
sufficiently large fat sample and still suffers from technical
difficulties.
Even though TCDD persists in the fat in amounts of a few parts per
trillion it is unlikely to present a "ticking time bomb" as has been
postulated. TCDD is found in fat in a higher concentration than in other
body components and fat ordinarily accounts for only 1/7 to 1/5 of the
total body weight of adult men. Even if all the body rather than adipose
tissue alone contained as much as 100 parts per trillion of TCDD and
released it simultaneously, the total amount would be much less than one
one-hundredth of that required (on a per kilogram basis) to cause toxic
symptoms in the most sensitive species.
These conclusions rest upon the accuracy of the assay employed for TCDD.
The dependability of the GC/HBMS analysis has been checked by
re-analyzing each extract and accepting only those results that are so
validated.
There remain two sources of contamination to be considered, one in the •
assay laboratory, the other in the surgical procedure. The former can be
dismissed if analyses at another laboratory confirm the results. To this
end, portions of eight samples were sent to scientists at the
Envionwental Protection Agency (EPA). They employ different but
complementary GC/MS procedures, using high resolution capillary column
gas chromatography with lower resolving power mass spectrometry than in
the present assays. Their results are in substantial agreement with
those reported here.

�Although precautions were taken against contamination with interfering
substances such as hexachlorophene during biopsy and tissue recovery, it
is possible that TCDD may have been introduced in some unrecognized
manner. This seems unlikely and unknown contact with the chemical during
daily civilian activities is more probable.
Despite these reservations, the data suggest that service in Viet Nam
increases the likelihood that a veteran's adipose tissue will contain a
small but detectable amount of TCDD. The amounts are so tiny and the
assay so delicate, however, that failure to detect TCDD does not indicate
that there was no exposure to the compound a decade or more ago.
Symptoms, signs, and laboratory results on each of the volunteers are
being collectd to attempt a correlation with the assay results.

DIRECT TESTIMONY OF DR. MICHAEL L. GROSS

My name is Michael Lawrence bross.

I am professor of

Chemistry and Director of the Midwest Center of Mass Spectrometry
at the University of Nebraska, Lincoln, Nebraska.

The mass

spectrometry center is one of six regional instrumentation
facilities that were formed in 1978 by the National Science
Foundation.

I received my Ph.D. in Organic Chemistry with minor

in Physical Analytical Chemistry in 1966 at the University of
Minnesota in Minneapolis, Minnesota.

After one year of postdoctoral

research at the University of Pennsylvania and one year at Purdue
University, I was appointed assistant professor of chemistry at
the University of Nebraska in 1968.

In 1972, I was promoted to

associate professor (with tenure), and in 1978, to professor.

A

curriculum vitae is attached.
My research interests are divided among three areas, all related
to gas-phase ion chemistry and mass spectrometry: (1) fundamental
properties of organic gas-phase ions, (2) environmental chemistry,
and (3) instrumental developments in mass spectrometry.

In the

environmental area, our laboratory has performed numerous analyses

at trace levels for pesticide residues and toxic substances such
as polychlorinated dibenzo-p_-dioxins.
The purpose of my testimony is to provide information on the
detection and measurement of TCDD in some human and environmental
samples.

This information is based on analyses in my laboratory

which show that measurable amounts of TCDD have been found in
some samples of soil, fish and other aquatic biologicals, and in
deer and human fat tissue.

BACKGROUND
Since 1977, our laboratory has provided analytical support

for several different projects involving the determination of
TCDD levels in human and environmental samples.

These projects

have been sponsored by various private and governmental agencies,
such as the Environmental Protection Agency, the U.S. Air Force,
the U.S. Department of Agriculture and the National Science
Foundation.

A brief overview of these several projects is

presented below.
Work in our laboratory with tetrachlorodibenzo-p-dioxin

;/

(TCDD; began in 1977 and was supported by a contract with the
Environmental Protection Agency.

The focus of this research was

the analysis of TCDD in a variety of environmental and biological
samples including soil, blood, adipose, liver and fish tissue.
Also during 1977, the analytical methodology currently employed
by the EPA and collaborating laboratories was validated over a
range of 2,3,7,8-TCDD concentrations from 9-81 parts-per-trillion.
During 1978, our work in this area continued with support
from the U.S. Air Force (Major A.L. Young was the project officer)
During that year we analyzed 100 biological and soil samples
taken from sites contaminated with TCDD.

The purpose of the work

was to evaluate the environmental fate of TCDD and TCDD uptake
into animal populations.

This work was continued in 1979 under a

V TCDD can exist""as 22 different isomers or as various mixtures
of these isomers. Throughout this document, the term "TCDD" is
used to indicate a mixture of TCDD isomers. When the term "2,3,
7,8-TCDD" is used, it refers to that specific isomer of TCDD.

second contract directed by Major Young.
addressed in 1979:

A new issue was

the movement of TCDD in biological samples

in the vicinity of the Herbicide Orange storage area at Gulfport,
Mississippi.

The results of the second study have been published

(Ref. 1).
In addition to the Air Force sponsored research, we did the
lead analytical work under a Cooperative Agreement with the EPA
directed at the analysis of TCDD in human milk from mothers in the
western forest areas of the United States.

Prior to beginning

this work, we participated in a validation study of the human
milk methodology at TCDD levels of 0-20 parts-per-trillion.
Sediment and water from Oregon were also analyzed during 1979.
This cooperative research program has been extended into 1980.
Another study conducted during 1979 was aimed at evaluating
the possible accumulation of TCDD in deer tissue in the Blodgett
National Forest in California.

This work was supported by a

grant from the U.S. Forest Service, U.S. Department of Agriculture.
A number of other TCDD monitoring studies were conducted in
1979 principally under the auspices of the National Science
Foundation Regional Instrumentation Facility Grant.
these studies deserve mention here.

Three of

In the first study, we

assisted scientists from the New York State Department of Health
with a preliminary survey of fish from the
from Lake Ontario.

.iagara River and

The results of this investigation were

announced publicly by Dr. David Axelrod, state health commissioner,
on April 24, 1979 (Ref. 2).

�-5-

The second study was a collaborative effort with Dr. Brenda
Kimble of the Laboratory for Energy Related Health Research of
the University of California-Davis, and was directed at evaluating
TCDD production in a coal-fired power house.

This work has been

published (Ref. 3).
The third project was with the U.S. Veterans Administration.
Its purpose was to examine whether Vietnam veteran exposure to
Herbicide Orange, a 1:1 mixture of 2,4,5-T and 2,4-D which
contained high concentrations of TCDD,

V

could be documented by

assaying adipose tissue taken ten years after the alleged contact
with Herbicide Orange.
In the remainder of this document, I will: discuss the
analytical methodology used in our laboratory, and the results
of some of the above projects which are based on our analytical
studies.
II.

Analytical Methods
The complete analysis of a sample for TCDD consists of two

operations:

sample extraction and clean-up, followed by the

actual analysis.

The sample extraction method for tissue employed

in our laboratory is called the acid/base procedure and was
originally introduced by Baughman and Meselson (Ref. 4) and then
perfected by scientists at Dow Chemical Company (Ref. 5).

It is

essentially the same method as that employed by Dr. Aubry Dupuy
and his co-workers at Bay St. Louis, Mississippi.
V T o date, there is no firm evidence indicating that 2,4-D
contains TCDD. Therefore, it is assumed that the TCDD in
Herbicide Orange comes from the 2,4,5-T.

�-6-

Although the methods vary somewhat with sample type, there
are some steps which are common to all.

A tissue sample is first

dissolved in an alkaline solution which serves to solubilize in
water all the fat and protein material.

Nonpolar materials, such

as TCDD, are then extracted into hexane, and most of the original
sample material is left behind in the water layer.

(When analy-

zing a soil sample the first step is the extraction of nonpolar
components into hexane.)

Once the sample is in hexane, the

hexane layer is cleaned up by washing with concentrated sulfuric
acid and performing one or more liquid chromatography steps.
These procedures remove low concentrations of potential interfering compounds so that TCDD can be freed and analyzed at the
parts-per-trillion level without interference from other materials.
The extract is then stored until analysis.

Details of these

procedures are contained in Appendix 1.
We employ packed column gas chromatography/high
mass spectrometry

resolution

(GC/MS) for the analysis of the extract.

The

mass spectrometer (a Kratos MS-50) possesses the highest resolving
power available in a commercial instrument.

We have demonstrated

an ultimate resolution of 180,000 (10% valley) which means we
could distinguish mass 180.000 from 180.001.

This resolving

power is not employed for the analysis of TCDD because the
sensitivity would be very poor; rather the resolution is chosen
to be 10,000 which is adequate to separate TCDD from other
interferences, notably polychlorinated biphenyls and DDE (a
metabolite of DDT), which could lead to false positives.

/description of the GC/MS analysis and a typical output showing
the resolution of potential interferences are presented in
Appendix 2.
Some considerations of our analytical procedure should be now
pointed out. First of all/ the method allows us to monitor each
sample at the exact mass of TCDD:

321:8936 + 0.0015.

This is

accomplished through the use of an internal standard (TCDD with
all chlorine atoms as Cl-37) which serves as a mass standard.
As a result, the analysis is highly specific for any substance
which has the formula C12H40235C1337C1.
dibenzo-p-dioxins have this formula.

All of the tetrachloro-

"~

V There are also other compounds which have this combination of
elements. The examples below are illustrative of substances
having the same mass as TCDD. However, having the same mass
does not automatically mean that a compound will behave as TCDD
in our analytical procedure. None of these subatances has been
identified in our analyses, and we postulate that they would be
removed in the sample clean-up or by the gas chromatography.

Second, the possibility of assigning a positive detection for
TCDD to the side of a peak from a very intense interference signal
is minimal because entire peak profiles are gathered for each
analysis.

Consequently, only a complete peak corresponding to

TCDD is designated as TCDD.

Therefore, the method is reasonably

unsusceptible to "false positives." Third, if a detection is
made, the analysis is repeated and both C^2H4°2

These are both expected signals from the TCDD molecule and should
be in the ratio of 1.00:0.78 (we expect to reproduce this ratio
to within + 10-15%).
to a detection.

This procedure adds additional assurance

Fourth, the measurement of the amount of TCDD,

if detected, is made by considering the intensity of the signal
relative to the internal standard.

This method (called the

internal standard method) is recognized as the best way to obtain
accurate quantitative results.
As is well-known, TCDD can exist as 22 different isomers.
Probably the most toxic isomer, that produced in the manufacture
of 2,4, 5-trichlorophenol, 2,4,5-T and silvex, is 2., 3,7,8-TCDD.
The mass spectrometer, as we operate it, is not capable of distinguishing among isomers; only gas chromatography can do this.
Therefore, a gas chromatograph is used in series with a mass
spectrometer in our and most laboratories doing TCDD analyses.
Our gas chromatography column, developed and evaluated by Dow

This ratio is also sometimes

scientists (Ref. 6), permits us to conclude that, if a detection
is made, it may be 2,3,7,8-TCDD or one of eight of the remaining
21 isomers.

Thus, our methodology has some, but not total,

specificity for 2,3,7,8-TCDD.

However, we often collaborate

with the EPA laboratory of Mr. Robert Harless, who employs even
higher resolving power gas chromatography that can distinguish
all of the isomers, to verify positive detections.
i
III. Validation Studies
It is well appreciated among analytical chemistry scientists
that analysis at parts-per-trillion levels is extremely difficult.
This is primarily because of the low levels involved.

To gain an

appreciation for this, consider that if one were measuring time
instead of chemical concentrations, one part-per-trillion corresponds to about one second in just over 30,000 years.

Compounding

the problem is the fact that most samples contain a multitude of
interferences which can complicate analyses at these levels.
Because of these difficulties, it is important to validate
the analytical procedures used at these low levels.

Therefore, it

has become customary for the EPA and its collaborating scientists
to periodically engage in validation studies, principally when a
new method or sample medium is used.

Our laboratory has partici-

pated in two validation studies which were designed to test the
analytical capabilities of the method we employ.

Both studies

were conducted blindly; that is, extracts containing unknown
amounts of TCDD were prepared by other scientists (Dr. Aubry
Dupuy and his co-workers at the EPA Toxicant Analysis Center in

�-10• Bay St. Louis, Mississippi) and then sent to us in such a way
that we could not know the amounts involved.

After analysis,

the results were then compared with the true values.

from "spiked" beef fat were studied.

(ca. 5 ppt).
This study shows that TCDD can be reliably
extracted, detected, and quantitated at the low parts-pertrillion level.
Before beginning the human milk monitoring project in 1979,
it was necessary to validate the extraction and analysis of TCDD
in this medium.

This was done in early 1979 in the same manner

as the 1977 validation of standard solutions and beef fat.

The correlation of

our results is less good, principally because the samples contain
lower concentrations of TCDD (1-20 parts-per-trillion). Nevertheless, the results show that TCDD can be reliably extracted,
detected, and quantitated (albeit less accurately than at higher
levels) in human milk.

Furthermore, no "false positives" and

only one "false negative" was found in the validation study and
*/
in the quality control samples
which were submitted along
with the extracts of the actual human milk samples.
To minimize the possibility of false positives and to add
certainty to analyses in which detectable levels of TCDD were
observed, a method validation approach was instituted in the
monitoring program as a standard procedure in 1979.

According to

this procedure, a sample showing detectable levels of TCDD in one
laboratory is reextracted and reanalyzed in another laboratory
for confirmation.

Most of our collaborative work has been

conducted with the EPA extractions laboratory (Dr. Aubry Dupuy)
at the Toxicant Analysis Center, Bay St. Louis, Mississippi, and
the EPA analysis laboratory (Mr. Robert Harless) at Research
** /
Triangle Park, North Carolina.
^7Quality control samples are extracts containing known
amounts of TCDD which are analyzed along with the true unknowns.
*_*/ The analysis procedure of Mr. Harless is complementary to our
own. He employs capillary column gas chromatography, high
resolution mass spectrometry, which, as previously mentioned, is
capable of distinguishing the TCDD isomers. However, unlike our
laboratory, he does not record signal profiles and works at
somewhat lower mass resolutions.

�-14Our criteria for assigning a positive detection of TCDD are
as follows:
1.

The gas chromatography retention time must be the same
as authentic TCDD.

2.

The suspected samples must give a signal at 321.8936
+ 0.0015 as determined by real-time peak matching using
the internal standard TCDD-^Cl as the reference mass.

3.

The signal intensity ratio of m/z 320:322 must be
1.00:0.78 ( + 0.10).

4.

The exact mass of m/z 320 must be 319.8965 + 0.0015
using m/z 321.8936 as a mass standard.

5.

The detected signal at m/z 321.8936 must be at least
2.5 times the noise level (refered to hereafter as a
2.5 S/N criterion).

Concluding this section, we note that TCDD can be reliably
analyzed in fat and milk at levels extending down to one part-pertrillion in milk.

These observations are important for they

lend credence to all trace analyses of TCDD done in this laboratory.
Furthermore, as a result of application of the stringent requirements cited above and employment of a "method validation approach",
we postulate that TCDD can be reliably detected at levels down to
1 part-per-trillion in similar types of samples.
IV.

Analyses of Environmental Samples
Our laboratory has participated in several studies which

have involved the analysis of environmental samples for TCDD.

�-15'Environmental media which have been analyzed in these studies
include soil, water, sediment, fish and other aquatic biological,
and fat tissue from deer.

Four of these studies are discussed

below.
A.

EPA Soil Study

During 1977, 16 soil samples from the forest area of Grays
Harbor County in the State of Washington were extracted and
analyzed in our laboratory.

These soil samples were collected

three hours after a normal spray of 2,4,5-T and then 15 days, 37
days, and 72 days after spraying.

They were composites of the

first 1" or the first 2" of topsoil.

No analyses were conducted

on the 15-day samples.
Twelve samples were found to contain detectable amounts of
TCDD varying from 8 to 40 parts-per-trillion (Ex. 224), with an
average detection limit of 6 parts-per-trillion
2 to 9 parts-per-trillion.
terms of sampling time.

and a range of

No trend could be distinguished in

That is, 1 of 2 samples taken on the day

of spraying contained 20 parts-per-trillion

TCDD; 5 of 6 samples

taken after 37 days showed TCDD at levels ranging from 8-31 partsper-trillion, and 6 of 8 samples after 72 days contained TCDD at
levels of '12 to 40 parts-per-trillion.
In addition, ten animal tissue specimens were extracted and
analyzed, but no TCDD was detected at an average detection limit
of 4 parts-per-trillion

(range of 1 to 7 parts-per-trillion).

�-16B.

Sediment and Water Study

In 1979, various samples of sediment and water taken from
the Alsea, Oregon area were extracted by EPA and analyzed in our
laboratory (Ex. 225).

The water samples were surface water taken

from fourteen sites in the Alsea area.

The samples were sub-

divided, extracted, and portions were analyzed by both Mr. Robert
Harless and by us.

No TCDD was detected by either laboratory;

i.e., the detection limit varied between 0.008 and 0.020 partsper-trillion in Mr. Harless1 laboratory, and 0.004 and 0.080
parts-per-trillion in our laboratory.

The average detection

limit using the lower value reported for each sample was 0.011
parts-per-trillion

(11 parts-per quadrillion) with a range of

0.004 to 0.020 parts-per-trillion.

We can conclude with high

certainty that no TCDD exists in these particular surface water
supplies at levels of 0.100 parts-per-trillion or higher.
Sediment samples were taken below the water at ten of the
fourteen sites investigated above.

The samples were extracted by

Dr. Dupuy and coworkers using both a neutral extraction and an
acid/base procedure.

In the neutral procedure, any TCDD in the

sediment was removed by extraction into hexane/acetone followed
by the usual clean-up.

In the acid/base procedure, the sample

was heated with an alkaline solution (as if it were a tissue
sample) and the resulting mixture was extracted to remove any
TCDD.

The samples were analyzed by Mr. Robert Harless and by us.
No TCDD was detected at seven of the ten sites investigated

at a detection limit of less than one part-per-trillion.

We

�-17believe we can say with high certainty that no more than one
part-per-trillion of TCDD exists at these seven sites.
However, at two sites, the results were more ambiguous.

For

example, at site #1, one analysis of the five conducted gave a
positive result at 2 parts-per-trillion; all the other analyses
showed no TCDD detected at detection limits ranging from 0.6 to
4 parts-per-trillion.

At site #4, two analyses were positive at

1.0 and 1.5 parts-per-trillion, but the results could not be
duplicated by additional extractions and analyses.

We can

therefore conclude with certainty that no TCDD exists at these
two sites at levels exceeding 3 parts-per-trillion; however,
lower concentrations may be present.
Finally, the sediment from one of the sites (#9) was shown
to contain significant amounts of TCDD.

The results for the

several analyses of this particular sample are as follows:

�-18The quality control samples done in our laboratory at the time of
our analyses of these sediment extracts tended to be low, and,
therefore, we think that our results are low.

Accordingly, we

postulate that TCDD does exist in these samples at a level between
10 and 20 parts-per-trillion.

Although the quantitative results

show some variability, we suggest that the important observation
is that all analyses of this sediment showed detectable levels of
TCDD in the parts-per-trillion range.
C.

Gulfport Study

Also during 1979, we collaborated with Major A.L. Young of
the United States Air Force to monitor biological samples for
TCDD in the area of Gulfport, Mississippi (Ex. 226).

Specifically,

the samples were taken near the Naval Construction Battalion
Center (NCBC), the site where over 15,000 drums (more than 80,000
gallons) of Herbicide Orange had been stored from mid 1968 until
mid-1977 (Ref. 1).

v

This area was unfortunately contaminated

with Herbicide Orange, including its TCDD component, because of
leaks in the drum containers.
The concentration of TCDD in the sail is highly variable at
this 1-2 acre site depending on whether or not spills had occurred.
The mean concentration of TCDD at spill sites in July, 1977 was

(Ref. 1).

�-19less than 0.2 parts-per-billion TCDD, whereas "old" spill (light
stain, mild odor) and "new" spill (heavy stain, strong odor) sites
were contaminated at levels of about 40 parts-per-billion and 200
parts-per-billion, respectively.
Clearly, the area contains TCDD at levels much higher than
soil exposed tc normal spray application of 2,4,5-T.

However,

the high levels allowed Major Young to develop an analytical
program to address the question of movement of TCDD in the
environment.

Our role in the program was to analyze biological

samples.
As has been reported by Young, Thalken, and Cairney (Ex. 226),
we found detectable levels of TCDD in a variety of biological
I/
samples (crayfish, mosquitofish, frog, etc).
The concentration
of TCDD decreased smoothly from levels of 100 to 7200 parts-pertrillion on site to levels of 45 parts-per-trillion at a distance
of 7000 feet from the site and 20 parts-per-trillion at 9000 feet.
The same trend was observed for samples collected later, in
June, 1979.

For example, for composite crayfish/mosquitofish

samples, levels of 175, 88, 31, 20, and 6 parts-per-trillion were
V W e have also participated in monitoring of TCDD from a
more normal environment. One study was conducted on fish in
the Niagara River and in Lake Ontario in collaboration with
scientists at the New York Department of Health. TCDD was
detected at levels of 4.6 parts-per-trillion in a small mouth
bass and 6.5 parts-per-trillion in a brown trout, both from
Lake Ontario (Ref. 2). The results are consistent with the
observations from Gulfport, but the origin of the TCDD and the
extent of the contamination is not clear from this preliminary
study. It is our understanding that more extensive investigations are underway in the New York Department of Health.

• found on site and at 3000', 7000', 9000', and 12,000' from the
storage area.

The complete data and a map of the area are shown

in Tables 1 and 2, and Figure 5.
These observations appear to be at odds with the commonly
held view that TCDD in soil is immobile (Ref. 7,8).

We must

point out, however, that for the usual environmental situation,
movement studies of this nature would not be feasible because the
site of origin of the TCDD (a spray site, for example) would be
contaminated at levels lower than the at parts-per-billion levels
found at NCFBC in Gulfport.

Clearly Major Young and his coworkers

have shown farsightedness in taking advantage of an inadvertant
contamination incident to generate useful environmental data.
Young and coworkers (Ref. 9) have also coordinated studies
on other biologicals at Eglin Air Force Base, Florida, a one
square mile site that was heavily sprayed with 2,4,5-T (161,000
pounds between 1962 and 1970).

The area contained rather high

levels of TCDD in 1973 (10-710 parts-per-trillion).

In 1978,

TCDD was still present, but no comparison can be made because of
sampling differences.

Based on results from many biological

analyses, it was shown that TCDD accumulates in animal tissues
(detectable levels were observed in nine species of animals).
For example, the liver of beach mice was shown to have up to 1500
parts-per-trillion TCDD, several times the amount in its surround;

ing habitat.

This work is ongoing, and we are collaborating by

providing analytical support.

Finally, a carefully designed study on the impact of 2,4,5-T

in the Blodgett Forest.

Deer were penned in an 11 acre area

The herbicide 2,4,5-T was sprayed at an

application dose of three pounds per acre.

Prior to the spraying,

fat biopsies were taken from all deer to be used as controls.
After the spraying, three deer each were sacrificed at intervals
of 2, 14, and 28 days.

Again samples of tissue (fat, liver,

muscle, and bone marrow) were taken.

Two additional deer were

collected from areas not known to have been sprayed with 2,4,5-T,
and tissues from these deer were used as controls (Ref. 10).
The tissue samples were extracted and cleaned up by Dr.
Aubry Dupuy at the Toxicant Analysis Center in Bay St. Louis,.
Mississippi using the "acid/base" procedure.

The extracts were

submitted to us (along with a suitable number of control samples)
for analysis using our standard method of gas chromatography-high
resolution mass spectrometry.

The results of our analysis as

originally reported to the Forest Service are presented in Table 3.
TCDD was detected in 18 of the samples of deer tissue that
were submitted to us for analysis (Ex. 227).

We have recently learned

that nine of these samples were quality control samples that had
been spiked with known amounts of TCDD (Ex. 228).

Studies are underway to determine the source

We believe these errors do not significantly

reflect on the validity of the study.

In our view, the key point

is whether TCDD can be detected in these samples; the exact levels
at the low parts-per-trillion range are of secondary concern.
Knowing that nine of the eighteen deer samples were spiked
as quality control samples, we concluded that the remaining nine
samples of

deer tissue contain TCDD at an apparent level of

1-10 parts-per-trillion.

However, if these determinations are

also systematically low because of an error made in our analysis,
then the levels would have to be raised by about a factor of three,

in human tissue.

the United States, and (c) human adipose from veterans of the

any of the samples at a detection limit of 5 parts-per-trillion
on the average (the range of the detection limit for 41 samples
was 1 to 12 parts-per-trillion).

Three samples had somewhat

higher detection limits: 17, 19, and 160 parts-per-trillion
because of small sample sizes for the first two and a poor
percent recovery for the third (ca. 1%).
B.

Human Milk Study

In 1979, we analyzed 103 human milk samples under the
auspices of a Cooperative Agreement with the EPA.

The 72 study

cases were mothers residing in northern California, Oregon, and
Washington state.

Control samples were taken from mothers in

Los Angeles and in Alaska, two areas where 2,4,5-T or Silvex
exposure is not likely.

The mothers were all volunteers.

Each sample was divided into two equal volumes, and one
volume was extracted and cleaned-up by Dr. Aubry Dupuy and his
coworkers.

(The second volume was reserved in the event that

reextration and reanalysis became necessary in order to resolve
questionable results from the first extraction.)

The extracts

along with controls were then submitted to us for analysis by
GC/High Resolution Mass Spectrometry.

As was discussed pre-

viously, the sample extraction, clean-up, and analysis was first
validated using control samples (see Ex. 225).
No TCDD was detected in any of the samples at detection
limits averaging about 1 part-per-trillion.

Clearly, no human exposure, documentable by milk analyses, is
evident at the detection limits shown above.
In the course of this study, an important observation was
made with reference to the analytical science of parts-pertrillion detections.

Nine samples appeared to be positive at

levels of 0.7 to 11 parts-per-trillion during the first round of
analyses in our laboratory.
using the second milk

These samples were then reextracted

portion and submitted to us and to Mr.

Robert Harless at the EPA Research Triangle Park laboratory.
The sample identity was not known to us.

In all cases, the

reanalyais gave a "not detected" result in both laboratories at
detection limits lower than for the first analyses.
This approach of checks and replicate analyses, carefully
designed by EPA scientists, permitted the analytical workers to
avoid reporting out "false positives".

Moreover, it is evidence

of the nonprejudicial manner in which government science has
sometimes been undertaken.

We can speculate that the first round

of apparent positives was due to handling errors either in the

�-29extraction or the analysis laboratories.

Furthermore, the positive

detections, later corrected, illustrate the need for caution in
the interpretation of analytical results at these low levels.
C.

Vietnam Veterans Study

The third study on potential human exposure to TCDD in which
we participated was conducted by the Veteran Administration, and
involved the analysis of human adipose taken from veterans of the
Vietnam war and a control group.

Fat samples were taken from 33

men, including a control group of 10 who had not served in Vietnam.
As of December, 1979, 22 of the 33 samples had been analyzed, and
dioxin was found in 10 of them (Ref. 11).

The Veterams Admini-

stration is currently reviewing the results of the analyses,
and their possible implications.

Conclusion
There now exist reliable methods for the extraction, detection,

and quantitation of TCDD at low parts-per-trillion levels in
soils, sediment, and tissue.

The validity of the methods is

insured by the validation studies, the stringent criteria employed
V O u r laboratory reported the results of its analyses to the
Veterans Administration on February 13, 1980.
In addition, the
results from some of these samples have been qualitatively
confirmed by Mr. Harless at the EPA analysis laboratory. Because
of the possible public reaction to the results and implications
of this study, the Veterans Administration has asked that the
data from our laboratory not be presented in an open forum before
the entire study has been reviewed by independent scientists.
However, the Veterans Administration is amenable to their use in
an iri camejra session, and negotiations are currently underway to
provide protective arrangements for the use of our data in this
hearing. Once these protective arrangements are in place, or the
review is complete, I agree to be recalled in this hearing in
order to present data from this study.

�-30in the collaborating laboratories, and the confirmation or method
validation procedure involving checks in a second laboratory.
Application of these analytical methods to real samples
permits us to conclude that measurable amounts of TCDD can be
found in some human and environmental samples.

In many instances,

the presence of the TCDD can be associated with exposure to 2,4,5-T.

�APPENDIX 1
Sample Extraction Procedure for Tissue
A 1-10 g sample was accurately weighed and spiked with a known
amount (2.0 - 2.5 ng) of ^CI-TCDD. It was then saponified in
I/
15 ml of ethanol
and 30 ml of 40% aqueous KOH in a reflux
apparatus for 60 minutes with stirring.

The sample should be

completely hydrolyzed before terminating the saponification.
The solution was transferred to a 250 ml separatory funnel
and diluted with 20 ml of ethanol and 40 ml of water and extracted
four times with nanograde hexane.

The first extraction was done

with 25 ml of hexane, shaking vigorously for one minute.

The

lower aqueous layer was removed to a clean beaker, and the upper
hexane layer was decanted to a 125 ml separatory funnel.

The

aqueous layer was then extracted three times more with 15 ml
portions of hexane, each time adding the hexane to the 125 ml
separatory funnel.

The combined hexane extracts were washed with

10 ml water to remove excess base.
The combined hexane extracts were washed 4 times with 10 ml

-5Sample Extraction Procedure for Soil

A 5-10g sample was accurately weighed in a 125 ml Erlenmeyer
flask and spiked with a known amount of ^CI- TCDD (2.0 - 2.5 ng).
The spike was allowed to dry on the soil before proceeding.

Four

ml of 0.2 M ammonium chloride solution (10.7 g/liter) were added to
saturate the soil.

The soil was allowed to stand for several

minutes.
Fifty ml of 1:1 (by volume) hexane/acetone solution was then
added; the solution was stirred for 15 minutes using a magnetic
stirrer.

The solvent was carefully decanted into a 250 ml

separatory funnel, filtering suspended particles through glass
wool.

Another 40 ml of hexane/acetone was added and the soil was

allowed to stir for another 30 minutes.

Again, solvent was

decanted and filtered.
The hexane/acetone solution was extracted twice with 25 ml
of IN KOH, followed by one extraction with 25 ml of distilled
water.

(Any emulsions formed were broken up by addition of a few

drops of concentrated H2S04-)

Several washings with concentrated

H2S04 were done, approximately 10-15 ml each, until hexane and
acid layers were clear.

Four or five extractions were generally

necessary.
The hexane layer was washed with 100 ml of distilled water
and excess acid was neutralized by addition of amounts of solid
Na2CO3 to the water/hexane mixture until the neutralization
reaction subsided.

The water layer was then removed.

Gas Chromatography/High Resolution
Mass Spectrometry (GC/HRMS) Analysis
At the time of analysis, the side of the centrifuge tubes
was washed thoroughly with aproximately 100 ul of hexane or
isooctane using a graduated syringe.

During the washing, the

solvent was allowed to evaporate until a volume of-^50 ul remained
This remaining volume was accurately measured; usually threefourths was replaced in the centrifuge tube, and the fourth
remaining in the syringe was used for the gas chromatography/
mass spectrometry analysis.
Mass Spectrometer
A Kratos MS-5076 ultra high resolution mass spectrometer was
used for this analysis (ultimate resolution = 180,000).

The mass

spectrometer was interfaced via a direct coupling to a Perkin
Elmer Sigma II gas liquid chromatograph.

Data acquisition was

accomplished with a Nicolet Model 1170 signal averaging computer.
Gas Chromatography
The column was a 6 1 x 1/4" O.D. glass containing a Dow mixed
phase packing.

Typical operating conditions were:

Helium flow

rate of 15 cc/min; injector 270°: column temperature program 1.5
min at 250° and then ramped at 10° c/min to 3008C and held there
until the dioxin had eluted.

The GC/MS interface was a simple

glass lined stainless steel capillary and was held at an average
temperature of 2508C.

Typical retention time was 3.4 minutes

(peak width at 10% height approximately 40 seconds).

Mass Spectrometer Conditions
The electron impact source was used at 70 eV ionizing energy
and an accelerating voltage of 8 KV.

The source was set at 260°C.

The instrument was tuned to a resolving power of 10,000 (10%
valley definition).
Data were acquired using the standard ion switching feature
pr./ided with the MS-50 (dual ion monitoring).

The first analysis

was made monitoring one channel m/z 321.8936 (the most abundant
molecular ion of TCDD having natural isotopic elemental abundances)
and m/z 327.8848 (3 C14-TCDD, the internal standard) on the second
channel.

The complete peak profiles were acquired at a bandwidth

of 3000 Hz by scanning of a frequency of about 2 Hz, corresponding
in each case to a mass range of 300 ppm (0.096 amu).

The output

of the mass spectrometer was accumulated over about 75 sweeps per
channel using a Nicolet Model 1170 signal averager.

The resulting

signals were submitted to a three-point smoothing routine prior
to print-out on an X-Y recorder.
Calculation of Results
Quantitation was achieved by employing the internal standard
"ratio method."

Throughout the analysis period, standard samples

containing TCDD and internal standard were analyzed.

From these

results, a calibration curve can be prepared by plotting ratio of
the weights of TCDD and internal standard versus the ratio of
signal intensities (intensity at m/z 321.8936; intensity at m/z
327.8848).

Residues of TCDD in actual samples were obtained by

�-3measuring the ratio of the signal intensities at m/e 322 and 328
(internal standard) and reading the concentration of TCDD from the
calibration plot.

The detection limit in the actual samples was

obtained by multiplying the noise level by 2.5 which was considered
the maximum amount of TCDD which could be present in the sample.
The percent recovery was measured using the absolute signal
intensity for the internal standard and mass spectrometer response
factors measured by analyzing standard solutions of internal
standard .
Validation
Samples which showed detectable concentrations of TCDD or
which were questionable were reanalyzed by removing a second
aliquot and reinjecting onto the GC/HRMS.

For this validation,

the high mass channel is centered at 321.8936 and the low mass
channel at 319.8965, the second most abundant molecular ion of
TCDD.

All other conditions were as reported above.

The theo-

retical ratio of intensities is 0.78 (m/z 319.8965: m/z 321.8936).
The analysis permits us to calculate a concentration of TCDD
based on the absolute signal intensity observed at m/£ 321.8936
using response factors determined for the mass spectrometer from
analysis of standard solutions of TCDD.

Based on the percent

recovery measured above, the quantitation is adjusted to 100%
discovery.
Validation of TCDD is considered acceptable if the observed
ratio of signals is 0.78 + 0.10.

�Dioxin in Body Health and Health Status:
A Feasibility Study
L. B. Hobson, L. E. Lee, M. L. Gross, and A. L. Young

Agent Orange, the defoliant used in Vietnam, contained
an average of about 2 parts per million of
2,3,7,8-tetrachlorodibenzo-para-dioxin or TCDD.

Since it is

extemely toxic for some animal species, it has been blamed
for a wide variety of medical problems by veterans who served
in Vietnam.
It was suggested that TCDD might remain concentrated in
the body's fat long after contact with it and serve both as a
cause of ill effects and as a marker to prove prior exposure
to Agent Orange.

It also became evident that improved

methods of gas chromatography and mass spectrometry would
allow detection of TCDD in amounts as small as a few parts
per trillion, a few picograms per gram of human fat.
In order to test the feasibility of using such assays,
the Veterans Administration undertook a pilot study with Dr.
Michael L. Gross of the Department of Chemistry, the University of Nebraska in Lincoln.

Three groups of men volunteered

to provide specimens of their fat:

twenty men, believing

that they had been exposed to Agent Orange in Vietnam and—
except for one man—experiencing medical problems submitted
to surgical biopsy of the abdominal wall.

A second group of

�ten veterans who were having operations anyway provided
specimens of fat from the body wall as control samples since
none had been in Vietnam nor had contact with Agent Orange.
A third group of three Air Force officers had worked with
TCDD or Agent Orange within the prior two years and one had
also been exposed to the defoliant in Vietnam.

They also

were biopsied.
To do this, VA surgeons removed 10 to 30 grams of fat
from the abdominal wall of the volunteers of the first and
last group using local anethesia.

In all instances

precautions were taken to avoid contaminating the specimens
with TCDD and to deliver them frozen to the assay laboratory.
I am not competent to discuss the methods of
extraction, gas chromatography and high resolution mass
spectrometry used by Dr. Gross.

Nor can I describe in detail

the techniques used by the chemists of the Environmental
Protection Agency who assayed 15 of the -specimens to confirm
Gross1 findings.

I am quite willing to believe that the

methods are delicate, exacting, and time-consuming.
Each volunteer had a medical work-up at the VA medical
center.

The military record of each "exposed" man was

examined to evaluate his exposure before the assay results
were available. The assays were conducted "blind" as well
since the chemist had only a code number for each specimen.
Estimating exposure to Agent Orange is generally a less

�than satisfactory procedure and the results must be viewed
sceptically.

We did divide, as best we could, the 20

"exposed" men into three subgroups:

the most likely exposed,

the least likely exposed, and an intermediate group with
possible but less definite exposure.
The results showed that it is indeed possible to detect
and quantify to some degree, at least, 2,3,7,8-TCDD in human
fat.

To be specific, it was present in fat from 13 of the 20

exposed veterans, from 9 of the 10 controls, and from all
three Air Force officers.

The amounts ranged from 3 to 99

parts per trillion with the two highest values in "most
likely exposed" veterans.

The third veteran in that group,

however, had no detectible TCDD and the heavily exposed Air
Force officer had only 6 parts per trillion.
It will be easier to review the results in graph form
(Slide I) than in a large table.

The front row of cubes
•

indicates the results from the most likely exposed
volunteers, the rear row of cubes refers to controls,

the

other two portray the possibly exposed and least likely
exposed groups.

Each cube stands for the highest value

obtained for one volunteer.

Only three individuals had more

than 15 parts per trillion and one of these was a control.
Most values were below 10 parts per trillion.
It is difficult in so small a sample to evaluate the
significance of an "outlier" such as the 99 parts per

�trillion, especially because of the intralaboratory, as well
as the interlaboratory, variability on replication.

It is

best to say only that a-larger series would have to be tested
with better documentation of exposure before any firm
conclusion can be drawn. This is especially true because two
recent small series, one in Canada and another in the United
States have found TCDD in fat samples from civilians, each
with a mean value of about 10 parts per trillion.

In Canada

one "outlier" of 130 ppt was discarded to arrive at that
mean.

The mean of our controls was 5.7^ 3.1 ppt, the mean

of the Vietnam veterans (except the "outlier") was 8.3^6.9.
In considering the clinical situations of the 20
"exposed" veterans, it must be kept in mind that all but one
volunteered because they had medical problems.
are a self-selected
Vietnam veterans.

Hence they

sample and are not representative of
The 19 men had a total of 36 diagnoses

ranging from the grave to the trivial. 'They are reasonably
typical of what can be seen in a large clinic serving a truly
sick population.

Thus, 8 men had minor skin problems, 4 had

blood vessel problems of high blood pressure or varicose
veins, 3 each had gastro-intestinal disorders, neuropsychiatric problems, benign tumors, joint diseases, or
reproductive disorders.

However, one of the benign tumors

was inside the skull, one man had sarcoidosis and another a
cancer, one was schizophrenic.

All of these are serious

�diseases.
I will show you the complaints, the diagnoses and the
TCDD values of only the most and least heavily exposed groups
in order to give you an idea of the results (Slide II).
First, please, notice the column of TCDD concentrations,
you can readily see, expecially for subject number 10, that
the assay presented some problems.

The "ND" indicates that

no TCDD was detected.
"S" stands for skin, "G-I" for gastrointestinal, "V"
for vascular, and so on.

Without going into detail, the

variability and the lack of relation to TCDD values is
obvious for both complaints and diagnoses.

One serious

illness—schizophrenia—was diagnosed in a man with 7 ppt
in his fat, the other—a cancer—was in a veteran with no
detectible TCDD.

Even a small series such as our 20 veterans

and 10 controls should reveal some correlation if these
levels of TCDD were associated with some one or two diseases
or groups of diseases.

There is no evidence of this.

There remains the question of whether the TCDD in the
body fat poses a threat to health, for example, if it were
all released into the blood within a very short time.

It is

most unlikely that there is any danger from this source.
TCDD concentrates in fat but even if all our soft tissues
contained 100 ppt, the blood concentration would only be 0.1

�microgram per kilogram of body weight, far below a dose
expected to endanger health.
At present, we do not recommend or provide an assay of
body fat for TCDD in order to determine whether a veteran was
exposed to Agent Orange or to evaluate his medical condition.
An operation is necessary to obtain a fat specimen, not
always a trivial undertaking.

The assay is difficult and

therefore expensive and, most important, the results of our
pilot study give no hope that useful information will be
obtained.
The assay unquestionably has value in research.

It

would be most desirable to follow the course of TCDD's
disappearance from fat after a known exposure to it.

It may

also help us detect suspected sources of TCDD in our civilian
environments but only on a very selective basis.

It is by no

means a practical screening procedure for occupational or
public health studies.

Since 1978 there has been mounting concern over human exposure to 2,3,7,8tetrachlorodibenzo-p-dioxin (TCDO). Much of this concern has been expressed by
veterans of the Vietnam war who believe that they were exposed to the
TCDO-oontaminated herbicide, 2,4,5-trichlocophenoxyacotlc acid (2,4,5-T), an
ingredient of Agent Orange, the major defoliant used by the United States Armed
forces In Vietnam.

During a 5-year period (com 1965 to 1970, the U.S. Air Force applied more than
40 million liters of Agent Orange containing more than 92 kg TCDO in South
Vietnam. Some two million American military personnel served t-yeac tours
during the same period. Many veterans of that era have reported medical
problems that they ascribe to exposure to Agent Orange. Their complaints have
ranged from tingling in the extremities to rare forms of cancer. Some veterans
have fathered children with birth defects and have suggested that the TCDO is
the cause. Accordingly, the Veterans Administration (VA) has initiated
extensive health studies of veterans exposed to Agent Orange and its dioxin
contaminant during the Vietnam Conflict.
Since TCDO is known to accumulate preferentially in the adipose tissue of
certain species of laboratory animals, it was suggested, early in the history of
the Agent Orange issue, that the analysis of human fat Cor TCDO might provide a
way to determine earlier Agent Orange exposure. A relation between the presence
of this substance health problems had also been suggested. Although methods for
TCDO analysis have Improved in recent years, no such study had been carried out
in humans with known exposure to herbicides containing this toxic contaminant.
Consequently the VA embarked on a small feasibility study to test the
methodology and to determine whether conclusions might be drawn regarding the
significance of the results. The study was carried out in three groups of adult
males as follows:
(1) Twenty Vietnam veterans all but one of whom claimed health problems
related to Agent Orange exposure and who volunteered for the fat
biopsy.
(2)

Three U.S. Air R&gt;cce officers with known heavy and relatively recent
exposure in connection with herbicide disposal operations but who did
not serve in Vietnam.

(3) Ten veterans with no service in Vietnam and no known exposure to
herbicides who were undergoing elective abdominal surgery and who
volunteered to serve as controls.
Methods; The procedure called for the removal of 10-30 grams of subcutaneous
adipose tissue from the abdominal wall. This was accomplished surgically under
local anesthesia. Precautions were token before, during an! after the procedure

�to avoid contamination by products, e.g., hexachlorophene, that could contain
TCDD. Specimens were collected In glass containers previously rinsed with
acetone and dried before use. All tissues were refrigerated during shipment bo
the assay laboratory, each of the volunteers had a medical history, physical
examination, and routine clinical chemistry. The details of military service in
Vietnam from the volunteer's report and his service record were examined to
evaluate his potential exposure to military herbicides using the dates, location
and nature of his service. Prom these a rough estimate of the likelihood of
exposure to TCDO was made without knowledge of the assay results.
The extraction and assay of all samples for TCDD were conducted at the
University of Nebraska, Midwest Center for Mass Spectrometry, Lincoln, Nebraska.
Approximately 5 to 10 grams of tissue were used, when available, for each
analysis. A known amount, generally 2 ng, of internal standard (either 37
C-2,3,7,8- TCDO or 13 C-2,3,7,S-TCDD) was added to the adipose tissue. The
sample was digested in alcoholic potassium hydroxide followed by extraction with
hexane to renove TCDD. The hexane extract was washed with concentrated sulfuric
acid, neutralized, dried and concentrated. The final stage of preparation
involved the use of three short-column liquid chromatography steps (silica gel,
alumina and Florisil). Gas chroinatography/hlgh resolution mass Spectrometry was
employed for quantitation of 2,3,7,8-TCDO and coeluting isomers. Signal
profiles were obtained at a mass resolution of 10,000 for ra/z 321.8936, the itost
abundant molecular ion for TCDD, and for the internal standard mass by signal
averaging for approximately 100 sec. commencing with the appearance of the
co-eluting internal standard 2,3,7,8-TCDO.
Extracts which contained materials giving signals greater than 2.5 times noise
at the exact mass of TCDD (i.e. 321.8936 + 0 0 2 ) over the Integration period
.00
discussed above were reanalyzed. For the~second analysis, signal profiles of
tn/z 321.8936 and m/z 319.8965 were nonitored over the elution period oC 2 3 7 8
,,,TCDO (determined by injection of standard solutions). A positive detection was
reported if signals were observed above the detection limit (2.5 times raise)
and if their intensity ratio was 1.0:0.78 + 0.10, which is consistent with the
presence of four chlorine atoms in the nolecule. Samples meeting all criteria
except the correct isotope intensity ratio have been considered to contain "not
detectable" levels of TCDO. Foe these samples, it was judged that the presence
of TCDD is not disproved by the observation of an incorrect isotope ratio at
these low concentrations; rather, the presence of TCDD is not confirmed.
Results; Of the twenty veterans who served in Vietnam, seven had no detectible
TCDD with the limit of detection at 2 to 6 part per trillion (ppt) . Another two
had detectible material that could not be validated as TCDD and the results for
one was considered equivocal because the measured value was only questionably
above the detection limit. Five of the ten remaining Vietnam veterans had TCDD
in amounts from 5 ppt to 7 ppt. three Vietnam veterans had TCDO in the amounts
from 9 ppt to 13 ppt. One individual had 63 and 99 ppt (average - 81 ppt) and
another had 23 and 35 ppt (average - 29
Of the ten control ("unexposed") veterans, four had TCDO identified in their fat
( , , and 14 ppt). Two other veterans had values low enough to be considered
677
equivocal and in three instances the detected material was not validated as
TCDO. The remaining veteran had no detectible TCDD.
One of the three Air Force officers with known exposure had no identified TCDD
in his fat. The unidentified substance in his case and the TCDD measured in the
other two officers was never more than 3 ppt above the limit of detection.

�The clinical data were reviewed, seeking correlations between complaints or
diagnoses and the assay results. Within the group of twenty Vietnam veterans,
seven of them reported some health problems beginning in or during a tour of
duty in Vietnam. No two, however, reported the same symptoms. The remaining
thirteen veterans reported no illness in Vietnam although only one reported good
health at all times. Anong the nineteen veterans with current medical
complaints, symptoms and diagnoses varied widely without any common pattern.
Five had mental problems ranging from nervousness to schizophrenia and three had
experienced difficulties of reproduction, namely, spontaneous abortion by the
wives of two and congenital heart disease in the son of a third.
Pour of the seven veterans who reported difficulties while in Vietnam had no
TODO detected. The five veterans with mental problems included three without
detectible TCDO and three whose assays results were 5 to 7 ppt. Che of three
veterans reporting reproductive problems had no detected TCDO, one had doubtful
level and one had 7 ppt. Detectible TCDO in the body fat could not be
correlated with clinical chemistry findings. Similar results applied to the
controls i.e., veterans who did not serve in Vietnam.
The highest values for TCDO in adipose were found In two Vietnam veterans. Both
men had military records substantiating duties that involved the use of
TCDD-oontaminated herbicides in Vietnam. Other individuals, however, who
claimed extensive handling of herbicide in base perimeter operations had little
or no TCDO in their adipose.
Discussion; TCDO was found in some persons who reported exposure to Agent
Orange and in others who were never in Vietnam. On the other hand, some
veterans from Vietnam had no detectible TCDO and the same is true of veterans
who were never in Vietnam. The low level of TCDD in two Air Force officers and
its absence in another is of special interest since their exposure to TCDO is
certain and more recent than that of the veterans.
Among the twenty Vietnam veterans there was no uniformity of symptoms, either
Immediately after exposure, at the time of biopsy, or during the Intervening
period. N&gt; one symptom or group of symptoms was common to veterans with
detectlble TCDO in their fat. The presence of TCDD did not mean ill health nor
did its absence indicate good health, tb detailed statistical analysis was
attempted of this small pilot series.
The TCDO content in the fat was very small, not exceeding 100 ppt. Since TCDO
accumulates in fat more than in other tissue, the average body concentration
woald be much lower. Even if all tissues contained 100 ppt, however, the
concentration would be less than 0.1 mircogram per kilogram of body weight, a
value below the demonstrated toxic dose to threaten health.
Conclusions; The present assay for TCDO in fat tissue does not offer a
satistactdry routine test for exposure to Agent Orange, providing neither clear
evidence of contact with that specific defoliant nor of absence of such contact.
Moreover, the technique cannot be used to correlate body levels of TCDO and
medical conditions. The assay technique is difficult and not readily available,
fat'samples must be obtained by surgical biopsy and the source of any TCDO
detected is uncertain. The current assay method does provide a research tool
under proper conditions and for specific purposes, e.g., for determining the
rate of disappearance of TCDD after known exposure.

Welcoming Richard Queen
son's release are entirely natural. That they included a word of gratitude toward Ayatollah
Khomeini undoubtedly reflected the courteous
impulse of a gracious woman. However, such
gratitude brings to mind Anna Freud's report on
child refugees from the blitz of London; the children spoke of the "good Jerries" who dropped,
thsir bombs next door but not on them.
There are strange psychological dimensions to
any captive-captor relationship. Sometimes they
can be manipulated to a prisoner's advantage.
There is nothing wrong with the way Ambassador Diego Ascensio reasoned when he tried to
establish a rapport with the terrorists who held
him and a clutch of other diplomats in Bogota a
few months ago. It has to be harder to kill someone you've laughed and joked with than it would
be to kill a stranger.
It is also true that it is wise not to antagonize
anyone holding a loaded gun to your head. As
Mr. Queen's release did not call for gratitude, it
did not call for berating the ayatollah.
In the present stalemate, nobody seems to have
a better idea of what to do about the hostages
than waiting for the revolutionary frenzies to
subside. The hope is that, one of these days, "a
decent respect for the opinions of mankind" will
persuade a moderate Iranian government to release the rest of the hostages.
Meanwhile, the important thing is to keep a
dignified perspective on what has been going on.

The release of vice consul Richard Queen from
captivity in Iran offers more cause for pure celebration than we've had out of a public event in
some time. A hard trial has ended for an exemplary young American diplomat. Two anxious
parents have their son back. An ailing person
will have the treatment he needs.
There is even a measure of political good n e ws
in the picture. That Ayatollah Ruholnh
Khomeini is enough concerned about how his
actions look to the rest of the world to release a
sick hostage rather than to let him languish or
die in continued captivity strikes a note of hope
for the rest of the American prisoners in Tehran.
It puts a bit of solid evidence behind the belief,
so long held on the most insubstantial grounds,
that there is a certain desire in high places in
Iran to get rid of the embarrassment of the hostages.
However, this is where the cautionary notes
come in. It is prudent to remember how cynically the ayatollah used the last hostage release
as a propaganda lever. More is at work than humane impulses when the man who is currently
ordering Iranian women back into cover-up
clothes they don't want to wear says he is letting
some of his American women prisoners go out of
sympathy for women's status as an oppressed
class in the United States.
It is prudent, too, to keep the "generosity" of
the ayatollah's act in perspective. Mr. Queen's
mother's expressions of joy and relief at her

Foreign Aid Needs Help, by Any Name
To the departing Secretary of State, Cyrus .Vance,
the decline in United States aid to the developing countries was "disgraceful." To his successor, Edmund
Muskle, there is also a practical reason for alarm. He
points out that Congressional cuts are depriving the nation of a weapon of influence to block Soviet, and Marxist advances in the third world.
'*•"
This return.to cold-war rhetoric should not be
shocking in the wake of the invasion of Afghanistan.
Even leaders who have no taste for simplistic sloganeering are desperate for ways to arouse the public to a
major issue of national security.
The American record is devastating. As a percentage of the gross national product, development aid
dropped from better than .5 percent in the EisenhowerKennedy years of 1960-63 to less than .25 percent in the
Nlxon-Ford-Carter period of 1973-78. Last year, the proportion fell to a low of .19 percent. Among the 17 aidgiving industrial democracies, only Italy ranked lower.
• We and others have always believed in the old saying that "foreign aid has no constituency." But the
.Agency for International Development disagrees, citing an opinion survey which shows that there are two
unorganized but potentially influential constituencies
for aid: a "constituency of conviction," favoring an
enlightened foreign policy and an overlapping "constituency of interest" that depends on third-world trade. If
£80, well and good. But what seems more important
the ineffectiveness of the aid constituencies is

WASHINGTON STAR

LINCOLN, Neb. — Traces of Agent
Orange, a controversial chemical defoliant used in the Vietnam War,
were found in tissue samples from
an entire test group of 33 men in a

the skill and persistence of the opponents of, aid.
One reason may be that in recent years the argument for aid has been cast not as anti-Communist but
as pro-American: meeting "basic human needs" in the
poorest countries would also advance the American interest in political stability and an open, growing world
economy. The argument is sound, but doesn't sell well.
The opponents of aid, meanwhile, have exploited
the Communist bogey. They have endangered the
World Bank and regional development institutions by
enacting unworkable prohibitions on help to Communist Vietnam and other regimes of a more ambiguous
stripe. The year-long Congressional hold-up of bilateral
aid to Nicaragua to hinder what they call a "Marxist
Sandinista" regime has instead strengthened those
.who prefer to get help from the Communist world and
has weakened the allies of private business and democracy. American aid for an important land reform in El
Salvador, for example, will be impossible unless Congress removes Senator Helms's prohibition, which the
Senate accepted last month without debate.
As Mr. Muskle noted, declining American aid and
influence "help the Soviets exploit internal Instability in
Nicaragua, in El Salvador and in many other places."
Mr. Muskie knows Congress. With the 1980 aid bill still
stalled in a political season, he is meeting the opposition
on its own ground. It is regrettable that the appeal for
aid has to be based on fear and negative reasons, but the
need for it, on any ground, is obvious and urgent.

recent experiment, says a University
of Nebraska researcher. Dr. Michael
Gross, director of the university's
Spectrometry Lab, said the study was
performed for the Veterans Administration. He said samples from 20
veterans who claimed exposure to
the chemical defoliant were brought
to the lab for testing. The control

group consisted of samples from 10
vets who did not believe they had
been exposed. Three additional samples came from Air Force officers
who had been involved in research
on Agent Orange. The study found
that all 33 had traces of Agenj
Orange in fat cells, but that none of
the samples had lethal amounts.

Seven Helicopters of Air Station
At Norfolk Reported Sabotaged
NORFOLK, Va., July 14 &lt;AP) — All
seven Navy helicopters assigned to a re^
serve squadron at. the Norfolk Naval- Air
Station were sabotaged last week, the
Navy said today. It was the second time
this year that a group of helicopters at the
base had been put out of action.
The electrical cables on each of the
seven aircraft, described as HH-1K single-engine helicopters, were cut Thursday in nearly identical areas, according
to a Navy official who asked not to be
identified. The helicopters are assigned
to Helicopter Attack Squadron Light 4.
On Feb. 20, in an adjacent building at
the air station, nine CH-46 helicopters
were similarly damaged. Those aircraft
were assigned to Helicopter Combat
Squadron 6, a regular Navy unit. The
Navy is investigating both incidents. No
arrests have been made.

New Air Force Tanker Is Tested

Navy Runs Short of Funds
For Re-enlistment Bonuses

LONG BEACH, Calif., July 14 (AP) —
A new KC-10 cargo-tanker, which will
allow the Air Force to deploy fighter
planes and men anywhere in the world
without landing at foreign bases, made
its debut Saturday with a flawless test
flight from here to Yuma, Ariz., according to its builder, Douglas Aircraft Company. The plane, converted from the
Douglas DC-10, will undergo nearly 300
more hours of test flights.

European-based nuclear-armed planes be
included in any new limitation formula
that would put a lid on Soviet deployment
of SS-20 missiles.
The Soviets originally demanded that
the nuclear-armed planes and submarines
be covered by the SALT II agreement, but
U.S. officials Insisted that the strategic
arms limitation should apply only to
weapons with a range of 3,000 miles or
more.
The SALT II agreement was signed by
both super-powers, but the U.S. Senate has
refused to consider ratification of the
treaty in the wake of the Soviet invasion
of Afghanistan, Both sides are observing
its spirit, and the Carter administration
remains committed to seeking its approval on Capitol Hill once the political
situation changes.
After his Bonn talks, Mr. Christopher is
to call in at Brussels for discussions which
one official said would be focused "in
large part" on the NATO response to th»
Soviet interest in new arms talks.
Other officials said that it wouM take

WASHINGTON, July 14 (AP) — An

running out of money to pay bonuses for

"Personnel eligible for selective resnlistment bonuses have been electing to
continue their Navy careers in larger
numbers than previously anticipated,"
Navy headquarters told its commands in
a message. It cited a number of possible
reasons, including "the prevailing state
of the civilian economy" and Congressional moves to increase service pay and
allowances.
Navy personnel officials said money
for such re-enlistment bonuses had not
been exhausted, but that steps were being

LINCOLN, Neb.; July 13 (AP) —
Traces of Agent Orange, the chemical defoliant used in the Vietnam War, were
found in tissue samples from an entire
test group of 33 men in a recent, experiment, according to a University of Nebraska researcher.
Dr. Michael Gross, director of the university's Spectrometry Laboratory, said
that the study was conducted for the
Veterans Administration, which is .trying
to find out how much Agent Orange may
have been absorbed by American servicemen in Vietnam.
Dr. Gross said tissue samples from 20
veterans who reported exposure to the
chemical defoliant were used. The control group consisted of samples from 10
veterans who.; did rtpt believe they had
been exposed. Three additional samples
carne from Air Force officers who nad
bean involved :in research on Agent
Orange.
. .
The study found that all 33 had traces of
Agent Orange in fat cells that were surgically removed for testing, Dr. Gross said,
adding, however, that none of the samples had lethal amounts of the chemical.
He noted that long-term effects of
Agent Orange were not known.
Charges of labor racketeering were returned against seven men, including the
president of the Teamsters union's Wilmington. Del., local. The indictments came from
a five-year federal Inquiry into enterprises
that allegedly left truck drivers jobless after
leasing them to other corporations.

PESTICIDE &amp; TOXIC CHEMICAL NEWS

DRAFT VA DIOXIN STUDY SAYS VA CAN'T BE CERTAIN OF TCDD SOURCE IN VETERANS
A Veterans Administration's (VA) study of TCDD in the body fat of veterans concludes
the VA can't be certain of the source of dioxin found in any of the men in the study
(See May 14, Page 18). It stated:

"

''The data indicate that TCDD can be found in some persons who report exposure to
Herbicide Orange and in others who were never in Vietnam and know of no contact with
the herbicide. On the other hand, some veterans from Vietnam have no detectable TCDD
and the same is true of veterans who were never in Vietnam.. .Information regarding preand post-service exposure to chemicals that contain TCDD is too inadequate to allow more
than speculation on other sources of the material in the fat samples. TCDD has been
found in a substance other than Herbicide Orange or the 2,4,5-T in that mixture. It is
impossible, therefore, to be certain of the source of TCDD found in any of the men in
this study."
The unpublished draft is being sent to the White House, the National Academy of
Science's National Research Council and the Office of Technology Assessment for
. review by the VA's Dr. Lawrence B. Hobson, Deputy Assistant Chief Medical Director
for Research and Development. The findings in the VA report included:
"Of the twenty veterans from Vietnam, seven had no detectable TCDD with a limit of
detection at 2 p.p.t. to 4 p.p,t.; another two had detectible material that could not be
validiated as TCDD and one could be considered equivocal because the measured value
was so low as to be questionable. The ten remaining men had TCDD identified and
measured in amounts from 3 p.p.t. with a limit of detection of 2 parts to 96 or 100 p.p.t
with 10 parts limit of detection.
The VA study also said that out of 10 veterans unexposed to the herbicide, two had TCDD
identified in .their fat at 5 p.p.t. and 6 p.p.t.
Another finding reported by the VA was that out of three Air Force officers known to have
been exposed to TCDD, one had no identified TCDD in his fat while the other two
had TCDD in the fat at levels between 12 p.p.t. and 96 p.p.t.
The draft also indicated the study failed to establish a cause-effect relationship
between exposure to TCDD and health problems. It said:
"Three of the seven veterans who reported difficulties while in Vietnam had no TCDD
detected; the four others had 5 p.p.t. to 96 p.p.t. Of the three men whose medical
complaints were difficult to relate to toxic substances, three had no TCDD and three had
5 to 96 p.p.t. The category of five veterans with mental problems included two without
detectable TCDD and three whose assay results were 5 to 13 p.p.t. One of the three
veterans reporting reproductive problems had no detected TCDD and the other two had
levels of 3 p . p . t . and 7 p.p.t."
It added: "Because of the difficulty and limited availability of the assay techniques,
the necessity for securing large fat samples, and the uncertainty of the source of the
TCDD detected, the method described here does not seem a satisfactory routine test
for exposure to Herbicide Orange nor acceptable evidence of contact with that specific

defoliant nor the absence of such contact."
Additionally, the VA study said the amounts of TCDD measured in the fat were
"very small," not exceeding 100 p.p.t.

EPA'S FINAL HAZARDOUS WASTE RULES PUBLISHED IN FEDERAL REGISTER

EPA's final hazardous waste rules with listings covering generators, transporters,
facilities and permits were published May 19 in the Federal Register (See May 14,
Pages 28 &amp; 29). The regulations are effective Nov. 19 except for parts of the rules
that were re-proposed.
Comments on the regulations will be accepted by EPA until July 18, according to
the notice. EPA will also hold three public meetings on the rules. The dates and
locations of the meetings are:
May 30—Sheraton Palace Hotel, 639 Market Place., San Francisco, Calif.
June 2—HEW Auditorium, HEW North Building, 300 Independence Ave., S.W.,
Washington, D.C.
June 6—Palmer House Hotel, 17 East Monroe St., Chicago, 111.
Comments on EPA's proposal to add eleven wastes to its listing are also due July 18.
The notice said EPA is reproposing its financial responsibility requirements to give
hazardous waste facility owners options in choosing trustfunds, surety bonds, letters
of credit, guaranties, financial tests and a revenue test for municipalities to provide
the necessary assurances for the cost of closure and post closure care. The new
proposal also includes a provision requiring liability insurance for interim status.
EPA said it is seeking comments on the proposed liability requirements by July 18 with
a public meeting scheduled for July 1. Those comments may include:
"Should the agency require insurance coverage for nonsudden and accidental occurrences
during the interim status period? "Will the insurance industry provide such coverage?
"Will such coverage be available on a continuing basis, or may the insurance industry
withdraw such coverage in the event of large damage suits ?
"Is the amount of coverage specified in the regulations appropriate ?
"Can we tailor the amount of required insurance to reflect better the degrees of risks
posed by the operations of particular sites ? How can this be done ?
"What will be the likely annual costs of insurance for nonsudden accidents ? Will all
firms be able to afford i t ? "

�WORKING PAPER
DEPARTMENT OF THE AIR FORCE
USAF SCHOOL OF AEROSPACE MEDICINE (AFSC)
BROOKS AIR FORCE BASE, TEXAS
78235

20 March 1980
Dr. Lawrence B. Hobson
Deputy Assistant Chief Medical Director

Dear Dr. Hobson
Thank you for extending to me the opportunity of evaluating the amount
of exposure sustained by selected participants of the TCDD-Fat Biopsy
Study. Although I feel my expertise might be of assistance to you, I
must respectively decline from providing you an "exposure rating." I
do so because I believe that if you and your staff were to use ratings
furnished by me, critics as well as concerned scientists might view
negatively that a study subject was providing interpretive guidance.
I concur with you that the development of an exposure index is critical
to interpretation of the TCDD analytic data. I would suggest that the
exposure index be constructed so that subjective notions be converted to
objective scales and that they be bounded to minimize any selected subjectivity of the rater. Thus a weighted rating system based on such
parameters as follow would be appropriate:
1. Year in Vietnam (exposure was potentially greater for an
individual in those years when RANCH HAND Operations were at a maximum).
2. Unit of Assignment Relative to Exposure (exposure was potentially
greater for a member of a RANCH HAND squadron than for a typical combat
soldier).
3. Base of Assignment (exposure was potentially greater for an
individual assigned to a RANCH HAND base; e.g., Bien Hoa, than for an
individual assigned to a non-RANCH HAND base; e.g., Phan Rang).
4. Duration of Exposure (the likelihood of exposure would have
been greater the longer an individual was in South Vietnam).
Other parameters might also be considered.
In my view, extreme care should be rendered in constructing the "exposure
index" and you should use qualified biostatisticians. Appropriate rank
correlation tests should be applied at a minimum* I would even recommend
that this subject be taken to the Interagency Work Group to Study the
Possible Long-term Health Effects of Phenoxy Herbicides and Contaminants.

�WORKING PAPER

Please understand that I am not in a position to respond fully to your
requested services as outlined in your letter. I believe it is appropriate that I not be placed in any position that might conceivably
jeopardize studies conducted by the Veterans Administration or the Air
Force. I have been made aware of Dr. Haber's contact with Mr. Joseph
Zengerle (SAF/MI) requesting my services on more than a part time or adlib basis. Because of this high level contact for my services or comments,
for the immediate future, further requests for my assistance should be
directed to SAF/MI.
Again, I thank you and other VA Staff members for this and past opportunities to assist in resolution of the Herbicide Orange issue.
Sincerely

Dear Dr. Hobson
Thank you for extending to me the opportunity of evaluating the amount
of potential exposure sustained by selected participants of the TCDD-Fat
Biopsy Study. Although I feel my expertise might be of assistance to you,
I must respectively decline from providing you an "exposure rating." I
do so because I believe that If you and your staff were to use ratings
furnished by me, critics as well as concerned scientists might view negatively a study subject providing interpretive guidance.
I concur with you that the development of an exposure index may be relevant.
I would suggest that any exposure Index be constructed so that subjective
notions be converted to objective scales and that they be bounded to minimize
any selected subjectivity of the rater. Thus a weighted rating system based
on such parameters as follow may be appropriate:
1. Year In Vietnam (exposure was potentially greater for an Individual
In those years when RANCH HAND Operations were at a maximum)
2. Unit of Assignment Relative to Exposure (exposure was potentially
greater for a member of a RANCH HAND squadron than for a typical combat
soldier).
3. Location of Assignment (Combat Tactical Zones and the Individual
Provinces varied significantly on the amount of herbicides they received).
k. Duration of Assignment (the likelihood of exposure would have been
greater the longer an Individual wa's In South Vietnam).
Other parameters might also be considered.
In my view, extreme care should be rendered in constructing the "exposure
Index" and you should use qualified blostatlsticlans. Appropriate rank
correlation tests should be applied at a minimum. I would recommend that
this task be undertaken by the Interagency Work Group established to study
the possible long-term health effects of phenoxy herbicides and contaminants.

                  <text>&lt;p style="margin-top: -1em; line-height: 1.2em;"&gt;The Alvin L. Young Collection on Agent Orange comprises 120 linear feet and spans the late 1800s to 2005; however, the bulk of the coverage is from the 1960s to the 1980s and there are many undated items. The collection was donated to Special Collections of the National Agricultural Library in 1985 by Dr. Alvin L. Young (1942- ). Dr. Young developed the collection as he conducted extensive research on the military defoliant Agent Orange. The collection is in good condition and includes letters, memoranda, books, reports, press releases, journal and newspaper clippings, field logs and notebooks, newsletters, maps, booklets and pamphlets, photographs, memorabilia, and audiotapes of an interview with Dr. Young.&lt;/p&gt;&#13;
