Recently the Veteran's Administration has inappropriately contacted members of this Division directly, both by phone and letter, requesting our assistance in sensitive areas related to Herbicide Orange studies. I am concerned that in our posture of expertise and willingness to help other investigators, we can inadvertently create political problems that could compromise both the VA study efforts as well as the Ranch Hand study. 2. Henceforth, refer all VA phone calls and letters to me for response. If the matter 1s purely technical, I will ask appropriate individuals to assist me in a conference call. If the VA inquiry concerns the complex aspects of how to conduct or interprete studies, resources, or policy, I will refer the call to Higher Headquarters. In my absence, Maj Rhode will make this decision; if we are jointly unavailable, the inquiry should be referred to Lt Col Moynahan. 3. Reply by endorsement. GEORGE D.

Page 1498 of 1514 �CHAPTER 9 "THE IMPORTANCE OF AGENT ORANGE AND DIOXIN WAS ACKNOWLEDGED WHEN THE HIGHEST LEVELS OF GOVERNMENT BECAME INVOLVED," THE POLITICAL ASSESSMENT: A CONGRESSIONAL VIEW MICHAEL GOUGII In December, 1979, Congress passed and President Carter signed Public Law 96-151, which instructed the Veterans Administration to carry out a study of possible long-term health effects resulting from exposure to dioxin-containing herbicides in Vietnam. This was not the first time that Congress had considered Agent Orange. Almost a decade earlier, in 1970, Senator Philip Hart; of Michigan held hearings about the possibility that spraying with Agent Orange was causing birth defects in Vietnam and that the use of the same herbicides could be harmful for the population of the United States. In response to those hearings, the Department of Health reduced the use of 2,4,5-T in the United States and the Department of Defense stopped Agent Orange spray missions in Vietnam. The law that was passed in 1979 mandating the Agent Orange study resulted from veterans testifying before Congress that Agent Orange had caused cancer, birth defects, and other health effects. It directed the Veterans Administration to study ground troops who had served in Vietnam to see if any long-term health effects in veterans or their families could be related to the use of Agent Orange. To prod the Veterans Administration along, Congress said that the protocol for the study had to be designed within 180 days or the Congress had to be told the reason why. 9: 1 �The OTA (Office of Technology Assessment), which is a technical support office of. Congress, was directed by law to review and approve the plans for the Veterans Administration study and to monitor the conduct of the resulting study. The bulk of my presentation is about OTA's role, but before going into that, I will discuss other major events in the Agent Orange issue. Some results are now available from the Ranch Hand study, the mortality and morbidity study of the Air Force personnel who flew the spray missions in Vietnam, which was well underway in 1979. The Air Force had responded early to Congressional inquiries and realized that they had an occupational health problem. They moved ahead on their own without the intense prodding Congress put on the Veterans Administration for the ground troop study. George Lathrop has dismissed those studies. Also in December, 1979, President Carter established the Agent Orange Working Group (AOWG), composed of Executive Branch agencies with programs that touched on possible effects on health of dioxin, Agent Orange, and herbicides. In February, 1980, the Office of Technology Assessment was invited to sit with the Agent Orange Working Group as an observer, and it became an active participant in this group. In August, 1981, President Reagan placed the Agent Orange Working Group into the Cabinet Council on Human Resources, elevating and enlarging the scope of the work group. The Agent Orange Working Group has had profound effects on Executive Branch efforts to try to better understand dioxin and Agent Orange. Among the several studies coordinated by the Agent Orange Working Group (ten major epidemiological studies scheduled for completion by 1990 and five ongoing health surveillance projects), one is complete. It is the 9: 2 �Birth Defects Study carried out by the Center for Disease Control. This study has two conclusions: the tfirst conclusion was that there is no association between service in Vietnam and birth defects. The second conclusion was th,a,t there may be an association between opportunities for exposure, to Agent Orange and a handful of birth defects, As soon a,s the results of that study were released, at least one bill was written in the Senate which was to provide compensation to all veterans who had fathered children with spina bifida, a. colleC" tion of tumors,and cleft lip with or without cleft palate, That legislation never left the Senator's office. The people who had clone the study at the Center for Disease Control, i.e., Dave Hricson and his colleagues, came to Congress. They talked to congressional staff in great detail about the structure of the study, its strengths and limits, and how to draw conclusions from its results. They also went to the American Legion, the Disabled American Veterans, the Vietnam Veterans of American, and other veterans organizations, where they explained the study and convinced those veterans that the connections that had been shown, although theoretically valid, woulcl not make a great deal of sense biologically. This was a great achievement for solid scientific exposition and convincing people not to be afraid and consequently do something foolish. Some scientists still argue about the meaning of those possible connections between exposure to Agent Orange and birth defects. The Birth Defects Study, like many of the other Agent Orange studies, was clone for political reasons. Politically, it has been examined and tried. The Congress looked at the conclusions and decided no harm had been associated with Agent Orange. So the CDC Birth Defects Study, from the point of view of politics, is over. The Congress will not reopen it. 9: 3 �It is Interesting to note in this context that in the Agent Orange lawsuit which was settled in the District Court of New York in May, 1985, Judge Weinstein also considered the CDC Birth Defects Study. He reached the same conclusion as Congress, deciding that the study results were not sufficient to sustain any association between Agent Orange and birth defects. Thus, in the judicial system also, the CDC Birth Defects Study has been weighed and found not to be convincing in demonstrating any association between Agent Orange exposure and b i. r th de f e c t s . These are events which are very important. It should be kept in mind that here we are not dealing with a purely scientific issue but with very sensitive and complicated political and social issues. The scientific conclusions, therefore, \vhile they are very important to us to understand whether or not: d.i.oxin and Agent Orange cause disease, still are less important to society than the decisions that are made in the courtrooms and in the Congressional Hearing Rooms. To come back to OTA, Congress wrote OTA into the Agent Orange study because of disagreement between the Senate and House Committees on Veterans' Affairs. Sensitive to veterans' complaints that the Veterans Administration was indifferent to their claims of harm from Agent Orange, the Senate wanted the study to be carried out by some other agency. The House Committee, on the other hand, had more faith in the Veterans Administration and acted to preserve Veterans Administration's responsibilities for research on veterans' health. The two committees compromised, giving responsibility for the study to the Veterans Administration and mandating that the Office of Technology Assessment make periodic reports to the committee, keeping Congress informed about progress or lack o f i t. 9: 4 �This was an entirely new role for the Office of Technology Assessment, and its constitutionality has been questioned. The question arose a month after Congress directed the Veterans Administration to do the Agent Orange study. At that time, Congress passed another law directing the National Institute for Occupational Safety and Health to do a study on dioxinexposed workers, and, again, Congress required that the Office of Technology Assessment review and approve the protocol and monitor the conduct of the study. President Carter vetoed that law on the basis that giving a congressional branch agency--the Office of Technology Assessment—veto authority over the execution of an Executive Branch study was a violation of separation of powers doctrine, Executive Branch lawyers concluded after examining the case that the bill was unconstitutional. Legislative Branch lawyers, however, concluded that it was constitutional. Neither branch has taken the case to court, and the issue is unresolved. The veto of the NIOSH bill was successful. President Carter's veto message also instructed the Administrator of the Veterans Administration to ignore the provisions of Public Law 96-151 which directed the Veterans Administration to submit the study plan to the Office of Technology Assessment for review. However, Senator Alan Cranston, at that time Chairman of the Senate Committee on Veterans' Affairs, wrote the Administrator that ignoring the provision would not be a wise course. He pointed out that Congress must provide funds for the Veterans Administration study and that funding depended, on the Office of Technology Assessment reviewing and approving the study plan. The Office of Technology Assessment was part of the process, and it has played an active role in Agent Orange issues ever since. 9: 5 �OTA assembled an Advisory Board to participate in its Agent Orange activities. The panel includes academics--epidemiologists and statisticians, a toxicologist, a neurologist, and a gynecologist. Then there are members who represent stakeholders. There are three representatives from chemical companies that made the Agent Orange components: Monsanto, Dow Chemical, and American Cyanamid. They are neatly balanced by representatives of the American Legion, the Disabled American Veterans, and the Vietnam Veterans of America. Despite the congressional requirement that a protocol be written in 180 days, the Veterans Administration did not produce one within that time. The Veterans Administration was sued by veterans' groups because of some of its procedures. There was a hearing before the General Accounting Office about the methods used by the Veterans Administration to contract for the protocol design. All of these events contributed to the protocol's being late. When the Office of Technology Assessment received the first draft of the protocol, we rejected it as inadequate. The basic plan of the protocol was to compare morbidity and mortality rates between two groups of veterans, one which had been exposed to Agent Orange and one which had not been. In response to OTA's and others' criticisms, the protocol was revised. The revision process just dragged along. It was not until September, 1982, two and a half years after Congress passed the law, that OTA approved the protocol. By that time the Agent Orange Working Group Science Panel had become convinced that it was really impossible to separate exposed from not- exposed veterans, and they were urging that a study be done to compare the health of veterans who had gone to Vietnam with the health of veterans who have not gone to to Vietnam, A study of that type would at least provide a 9: 6 �clue as to whether or not Vietnam veterans in general were suffering from ill effects as a result of that experience. The recommendation placed pressure on the Veterans Administration to do a "Vietnam Experience Study" even though the Administration was planning an Agent Orange study. Rather than making a decision between the two studies on its own, the Veterans Administration asked for another review of their protocol from the National Academy of Sciences. In September, 1982, all the delay came to a head because Congress had exhausted its patience. One hundred and: one representatives from the House of Representatives wrote a letter to the Veterans Administration requesting that the study be transferred from the Veterans Administration to some other agency. Dr. Vernon Monk of the Centers for Disease Control, in testifying before the House Veterans' Affairs Committee, said that the Centers for Disease Control was well placed to do the study. The Senate Veterans' Affairs Committee reaffirmed its previously held conviction that the responsibility for the study should be transferred somewhere else. The result was that the execution of the study was taken from the Veterans Administration and given to the Centers for Disease Control. The Centers for Disease Control finally resolved the controversy about whether to do an Agent Orange Study or a Vietnam Experience Study: they are doing both. The CDC studies are the largest, probably the most compjLicated, and the most expensive epidemiology studies ever conceived. They will cost at least $70 million, involve interviews of 30,000 veterans, and 10,000 physical examinations to be carried out at the Lovelace Clinic. The Vietnam Experience Study is relatively straightforward. Looking at the records easily establishes whether or not a veteran went to Vietnam. The two cohorts can thus 9: 7 �be easily assembled, with the men who went to Vietnam on one side and those who did not on the other; then their health can be examined. The Vietnam Experience Study is underway and on schedule. The same cannot be said about the Agent Orange Study,because it is much harder to say whether or not a veteran was exposed to Agent Orange. In January, 1985, the Centers for Disease Control sent the Office of Technology Assessment a summary of their efforts to resolve the exposure problem. At that time the Centers for Disease Control were able to identify the locations of battalions on the ground in Vietnam, A battalion is about 1,000 men, four maneuver companies and a headquarters company. The battalion that the Centers for Disease Control provided as an example was spread out along a line of 40 kilometers. It was not possible to know where the 1,000 men actually were. Were 990 at the middle of the line or were they at one end? Were they spread out evenly along the entire line? No one knows. One way to decide that a battalion was exposed is to declare that any Agent Orange spray mission within a fixed distance caused exposure. In practice, AOWG and CDC have accepted that a spray mission at a distance of two kilometers'might result in exposure. Now consider an airplane spraying Agent Orange somewhere within two kilometers of the battalion spread out on the 40 kilometer line. It is very hard to say who of the battalion was exposed and who was not. Even assuming that exposure could be ascertained, it is impossible to know how much exposure took place. OTA was very critical of the plans to decide a battalion was exposed on the basis of such data. This criticism was expressed in periodic reports sent to the congressional committees. 9: 8 �Right: now, I think a majority o£ the OTA Advisory Board feels that the study on Agent Orange should not go on because of difficulties in deciding who was exposed and who was not. The panel has not voted on this issue, and I could be wrong, in my assessment, but I don't think so, If, after seeing more details about exposure, OTA decides the study is impossible, Congress could decide not to do the study. That would involve an act of courage on the part of the Congress because it has made a commitment that this study would be done. The Veterans' Affairs Committees of the Senate and of the House may face the dilemma, having promised the veterans to do the study, that they have changed their mind. I used to think that, no matter what the technical problems, the study would be done. I am no longer so certain. Congress has considered, over and over again, providing compensation to veterans who claim ill effects from Agent Orange exposure. At one time there was a list of over 20 diseases being considered as compensable. Congress finally passed a law which provides compensation for chloracne and porphyria cutanea tarda (PCT), if they occurred within one year after .leaving Vietnam, Although there are very few cases of either disease, the law was not a hollow gesture on the part of the Congress. They wanted to do something to compensate veterans who had been harmed, but, at the same time, they wanted to limit compensation to diseases that might be connected with Agent Orange, Subsequently, Congress directed the Veterans Administration to set up a special committee to review claims about diseases resulting from Agent Orange exposure. That committee will function only until the studies of the Centers for Disease Control arc complete, because at that moment we expect to have the answer to our questions. 9: 9 �Summing up, we can say that Congress is working out the Agent Orange controversy. In 1979, Congress refused to make a decision about whether or not Agent Orange had caused health, effects. Instead, Congress directed the Executive Branch to gather information for making a decision. By now, some results have come in. The Air Force's studies on Ranch Hand personnel provide no convincing evidence that Agent Orange has affected human health. The Birth Defects Study, performed by the Centers for Disease Control, also failed to provide convincing evidence of a connection between Agent Orange and human effects. Congress has directed the Veterans Administration to compensate two conditions which have been related to dioxin exposure should they appear in Vietnam veterans. The judge in the Agent Orange class action stated that the veterans had failed, to prove their case in court that Agent Orange was the cause of their illnesses. These points are convincing many people that, regardless of all the fears about Agent Orange and the toxicity which might reside in the dioxin molecule, exposure to Agent Orange, if it occurred, has not harmed the veterans. However, that is not yet the end of the Agent Orange controversy. Intellectually and emotionally the veterans might accept that they have not been able to prove that their diseases were caused by Agent Orange, but they can always contend that no one could prove the contrary. Probably, Agent Orange will pass away as a political issue. Some veterans will continue to contend they were harmed, but the decisions already made in Congress and in the courtroom will convince many people that no detectable harm was done. As more study results come in, if the results continue to show no health effects, they will reinforce the conclusions already made. 9: 10 � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

The detection corresponded to a single isomer, having the characteristics of 2,3,7,8-TCDD, and was validated in inter laboratory studies for two of the three tissue samples. Tissue samples from other Vietnam veterans and from controls also contained 2, 3, 7, 8-TCDD at levels below 20 parts-per-trillion. These findings are in accord with uptake and long term storage of 2,3,7,8-TCDD by veterans who experienced a heavy exposure to Herbicide Orange. Furthermore, they may signal accumulation of 2, 3, 7, 8-TCDD in some members of the U.S. population. Aerial defoliation in Vietnam carried out by the United States military from 1962-1970 made use of Herbicide Orange/ a 1:1 mixture of the herbicides contaminant, 2r4,5-T and 2,4-D. The 2,4,5~T 2, 3,1, 8-tetrachlorodibenzo-p_-dioxin contained (2, 3, 7, 8-TCDD) a at levels sufficient to produce a mean concentration of about 2 partsper-million in the defoliant. The ,.2f 3, 7, 8-TCDD, in addition to being extremely toxic, is known to be carcinogenic and teratogenic in animal 2 tests. Vietnam veterans now claim adverse chronic and delayed health effects related to their exposure to Herbicide Orange. These claims and recent publicity regarding the m i l i t a r y defoliation program have increased public awareness of the potential health e f f e c t s of exposure to 2,3,7,8-TCDD, especially among Vietnam veterans. �- 3 - . We report here the results of a preliminary study designed to determine the range of TCDD levels that might exist in the tissue of veterans. Specifically, we wished to determine if 2,3,1, 8-TCDD could be detected at levels above 1-5 parts-per-trillion. was chosen as the preferred sampling medium Adipose tissue because of its good accessibility (compared to other tissue) and because 2,3,7,8-TCDD is O known to accumulate in this tissue in other species. ' wished to examine whether any correlation exists A Secondly, we between exposure (assigned by the Veteran's Administration ) and observed levels. existence of a correlation could signal the need for The additional monitoring studies. In order to have confidence in the results generated from test samples, it is necessary to demonstrate 'analyses of TCUD at low ppt levels. laboratories involved in this the capability to conduct This has been demonstrated in the analytical work by means of blind validation studies in which coded spiked samples of beef fat and human milk were analyzed. ' Additional validation of the methodology used in this study for low levels of TCDD has been demonstrated at the 1100 part-per-trillion range using human and beef adipose tissue (see Table 1) . The Veterans" Administration supplied thirty coded samples of adipose tissue which had been surgically removed from the abdominal area of "exposed" veterans and control subjects who had not served in Vietnam. Additional tissue was taken from three U.S. Air Force officers with several years experience in TCDD research. Particular care was exercised, even in tissue removal, to avoid any potential contamination. The samples were placed in rigorously cleaned glass �- 4 - vessels, f r o z e n , shipped in dry ice, and stored in a f r o z e n state (20 C) . No disinfectants containing hexachlorophene or other trichlorophenol-based materials were used.

Three of five samples of tissue from veterans having "light exposure" were found to contain TCDD, as were tissue from two of the three Air Force officers who have done extensive research environmental and biological samples containing 2,3,7, 8-TCDD. with Seven of thirteen tissue samples from other Vietnam veterans were found to contain 2,3,7,8-TCDD or coeluting isomers at levels between 3 and 13 �- 6- parts-per-trill ion. Samples taken from veterans who had no service in Vietnam (controls) also showed low levels of TCDD (four of ten were judged to be "positive" at levels between 4 and 8 parts-per-trillion). In view of the limited isomer specificity 14 of the methodology used at the University of Nebraska (UN-L) certainty by interlaboratory validation these low levels, a subset of and/or reanalyzed at other the and the need to increase of reported detections tissue samples was reextracted laboratories (see interlaboratory validation was done in two ways. the first stage of analyses at at UN-L were Table 3) . The First, extracts from reanalyzed at the Environmental Protection Agency laboratory at Research Triangle Park (RTP) using capillary column gas chromatography/high resolution mass spectrometry (reported as UN-L/RTP in Table 3) . the tissues stored in the University of Nebraska transmitted to the EPA Toxicant Analysis Center and clean-up. The extracts were then Triangle Park laboratory for analysis 3) . Second, portions of laboratory were (TAG) for extraction forwarded to the Research (reported as TAC/RTP in Table All samples were coded at the University of Nebraska and their identities were not known to the workers at TAG or RTP. The tissues were extracted at TAG using methods similar to those employed at the University of Nebraska. the RTP laboratory made use of The quantitation conducted at capillary column GC and peak-top monitoring (rather than peak profiles) at a mass resolution of 600010,000, a method more specific for TCDD isomers than that employed at the University of Nebraska. All detections reported in Table 3 were for a material having an identical GC retention time as 2,3,7,8-TCDD �_ 7 — and no other isomers were detected at levels greater than 10% of the level corresponding to 2, 3,1, 8-TCDD. Some small degree of uncertainty remains that the material detected is the 2,3,7,8-TCDD isomer because standards for all 22 TCDD isomers were not available at the RTF laboratory. Based confirmed on the that interlaboratory two of three validation samples from studies,it veterans is now designated as having "heavy exposure" were found to contain measurable amounts of 2,3,7,8-TCDD at levels higher than any other participant's tissue in this study. is Adipose tissue from the third "heavily exposed" veteran a "possible positive"; i.e./ the positive detection made by RTF scientists was not validated by the group at Nebraska, presumably because of the problem with recovery. Both the TJSAF officers'" adipose tissues, which were examined in the interlaboratory validation, definitely contained 2,3,7,8-TCDD, but at lower levels than the tissue of "heavily exposed" veterans. Definite detections of 2,3,7,8-TCDD were made in the analyses of adipose tissue from other exposed veterans and veterans who never served in Vietnam (controls). The detection of 46 ppt for VA-21 is considered an aberrantly high value based on a comparison with four other analyses reported in Table 3. Ignoring this value, the highest level detected in these two groups (20 ppt) coincides with the 1owest detection made for the "heavily exposed" veterans. may signal base-line accumulation of TCDD in These observations some members of the general U.S. population. There is good agreement of the results obtained in both mass spectrometry laboratories particularly in terms of the assignments o£ �- 8 - whether the sample contains TCDD. Differences in concentrations were found for repeated analysis of samples containing the higher levels of TCDD.

A contingency table for the hypothesis of independence was used' to test the supposition that "concentration levels of TCDD in adipose tissue of test Herbicide Orange". were used except individuals is unrelated to exposure to The exposure classifications as previously listed the Air Force scientists were excluded. concentrations of TCDD were classified in four categories: The (1) "less than four parts-per-trillion or not detected", (2) "4 to 10 parts-pertrillion", (3) "11 to 20 parts-per-trillion", and (4) "greater than 20 parts-per~trill ion". statistical The concentrations test were averages of. all detected" having detection limits used in the in both We did not use reports of greater positive detection made in separate analyses The "not detected" TCDD determinations made laboratories with the following exceptions.

The chi-square test showed that the hypothesis of independence was false at the 95% confidence level, indicating a correlation between degree of exposure to Herbicide Orange and tissue levels of 2,3,7,8-TCDD.

The observations that the TCDD observed is a single isomer, and likely the 2,3,7,8-isomer found in 2,4,5-T, and that the levels in the "heavily exposed" group are higher than those observed in any of the other study cases are in accord with an interpretation that the exposure occurred in Vietnam. We emphasize that the confidence ascribed to this conclusion can'be increased (or decreased) by conducting a more thorough investigation which would include a larger Orange. sample of Vietnam veterans "heavily exposed" to Herbicide �- 10 REFERENCES i tion of Orange Herbicide by Incineration, Final^ ^ ^ Environmental Statement, 36 (Department of the Air Force, November 1974) . 2.

A number of method blanks (14) were extracted and analyzed with actual tissue samples so that one blank for approximately every three samples (including repeats) was examined. No TCDD was detected in the blanks at at an^average detection limit of 4 and a range of 1 to 11 parts-per-trillion. 12. The classification as to degree of exposure was made by the U . S . Veterans Administration (see reference 5) . 13. The packed column used in these studies has been evaluated by Dow Chemical Company scientists in terms of TCDD isomer specificity (see reference 15). In our hands 2, 3, 7, 8-TCDD, for example, could be separated from 1,3, 6, 8-TCDD with base line resolution. 14. Another interlaboratory study, TAC/RTP, was conducted prior to the two reported in table 3. Analysis of method blanks showed that the glassware in the TAG laboratory was contaminated w i t h 2 , 3 , 7 , 8 TCDD and other isomers at the time of the study. None of these results are reported h e r e . All glassware was replaced for the �- 11 later studies, which yielded the results given in table 3. Actual adipose samples VA-9 and 10 were presumably contaminated d u r i n g the time of the f i r s t extraction at TAG as they were found to contain 160 and 230 ppt respectively in the second TAC/RTP validation run (coded TCDD TAC/RTP ) . These results are also not reported in Table 3 because they are clearly not consistent w i t h results of other analyses of these samples. Samples VA-26 and VA31 were not present in the TAG laboratory at the time of contamination. They and additional portions of tissue samples for the t h i r d validation run (Coded TAC/RTP ) were transmitted to TAG after the laboratory contamination had been removed. 15. T. L. Nestrick, R. S.

A. ElYoung, Department of Medicine and Surgery, Veterans Administration, Washington, D.C. Few environmental or occupational health issues have received the sustained international attention that has been focused on the phenoxy herbicides and their associated chlorinated dibenzo-p-dioxin contaminants. Although much of tiie present concern centers around veterans of the Vietnam Conflict who believe they were exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), a contaminant of the military defoliant "Agent Orange", the potentially larger issue is whether human health has been significantly impacted because of the widespread use of dioxin-oontaminanted herbicides to enhance agricultural production. During the 5-year period from 1965 to 1970, the United States Air Force applied more than 40 million liters of Agent Orange in South Vietnam. Some two million American military personnel served 1-year tours during the same period. Recently, many veterans of that era have reported medical problems that possibly . 9*. stem from exposure to Agent Orange during their military assignments. 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 Agent Orange is the culprit. Similar health issues have been raised by citizen groups in areas where the phenoxy herbicides are commercially used. Tb conduct epidemiologic studies of human populations exposed to the phenoxy herbicides and the dioxin contaminant, it is necessary to first know what health outcomes should be selected for study. Secondly, one must be able to identify a study cohort with a high likelihood of exposure and a control group with a low or no probability of exposure. Lastly, a sufficient number of individuals in each cohort must be located, recruited and examined in order to give statistical �validity to the results. These three requirements, so important for the conduct of valid studies, are in themselves not clearly defined with respect to either the chemicals used or the populations at risk. Health studies of the effects of phenoxy herbicides and/or the dioxin contaminant are very difficult under conditions of normal agricultural use, but become immensely more complex when conducted with cohorts briefly exposed over a decade ago during the conditions of war in a tropical environment. The basis for resolving the phenoxy herbicide controversy must in large measure stem from the results of scientific inquiry. Accordingly, the Veterans Administration (VA) in cooperation with other Federal Agencies in the United States Government has initiated extensive health studies of veterans exposed to Agent Orange during the Vietnam Conflict. In addition, numerous studies of non-veteran populations exposed to the phenoxy herbicides and TCDD have been initiated. To date, more than 20 human health studies have been or are now being conducted by agencies of the Federal Government. The cost of these studies presently exceeds 80 million dollars. The results" «f many of these studies will be presented. �WEED SCIENCE SOCIETY OF AMERICA TWENTY-FOURTH MEETING 1984 PROGRAM Hyatt Regency Miami Miami, Florida February 8-10, 1984 Theme WEED SCIENCE AND HIGH TECHNOLOGY �1983-1984 Executive Committee of the WEED SCIENCE SOCIETY OF AMERICA C.

Smith Science Policy Research Division THE LIBRARY OF CONGRESS CONGRESSIONAL RESEARCH SERVICE MAJOR ISSUES SYSTEM DATE ORIGINATED 09/06/79 DATE UPDATED 04/20/82 FOR ADDITIONAL INFORMATION CALL 287-5700 0426 �CRS- 1 IB80040 UPDATE-04/20/82 ISSUE DEFINITION From 1962 to 1971, the United States Air Force (USAF) sprayed various herbicide mixtures (chemicals that kill plants) in South Vietnam. The purpose of the spraying was to defoliate jungle growth to deprive the Communist forces of ground cover, and to destroy enemy crops to restrict food supplies. The most extensively used of these herbicide mixtures was known as Agent Orange, a 50:50 mix of two common herbicides called 2,4,5-T and 2,4-D (2,4,5-trichlorophenoxyacetic' acid and 2,4-dichlorophenoxyacetic acid). A third chemical present in the mixture in small amounts was TCDD, an inevitable by-product of the manufacture of 2,4,5-T. This chemical, called tetrachlorodibenzo-para-dioxin or simply "dioxin," is highly toxic to laboratory animals when administered in its pure form. Acute (short-term) toxicity values in humans have not been established, although Gosselin et al., in the 1976 edition of Clinical Toxicology of Commercial Products, puts TCDD in a class of chemicals for which the "probable lethal dose" for humans would be less than 5 mg/kg, or about 7 drops for a 150 Ib (70 kg) person. CRS has been unable to locate any report of a human death from exposure to pure TCDD. The human health effect that has been most consistently documented following exposure to small amounts of TCDD as a contaminant in other compounds is a skin condition known as chloracne. There is other, less consistent, evidence of damage to the liver and the nervous system in humans. Extensive testing on laboratory animals has been done to determine possible long-term effects of exposure to TCDD. It can induce cancer in some strains of rats and mice (carcinogenicity) , cause fetal death in several species (fetotoxicity) and birth defects in developing mouse fetuses (teratogenicity), but has been found not to cause genetic changes in mammalian cells (mutagenicity). The American Medical Association's Council on Scientific Affairs concluded that "there is no scientific evidence that 2,4-D, 2,4,5-T or TCDD has caused reproductive difficulties or hazards in the human. " Congressional interest was triggered by receipt of reports from Vietnam veterans who believed they had been harmed by exposure to herbicides, particularly Agent Orange. The 96th Congress held numerous hearings on the use of herbicides in South Vietnam, and various initiatives to deal with the problem were introduced. P.L. 96-151 was enacted to direct the Veterans Administration (VA) to conduct an epidemiological study on Vietnam veterans to determine whether there may be adverse human health effects associated with exposure to phenoxy herbicides and/or dioxin. This study and other studies planned will help elicit answers to the scientific questions posed by the Veterans Administration in determining whether or not the veterans' medical problems, allegedly due to exposure to Agent Orange and associated herbicides used in Vietnam, are compensable. Following recommendations made by the Interagency Work Group on Phenoxy Herbicides (now the Agent Orange Working Group), legislation was introduced in the 97th Congress to expand the scope of the VA's epidemiological study of the health effects of Agent Orange to include other factors related to military service in Vietnam. The legislation also allows veterans with medically certifiable conditions that might possibly have been caused by exposure to Agent Orange to receive medical care in VA facilities. The bill (H.R. 3499) was considered by the House and Senate in June 1981, put into final form in October, and signed by the President Nov. 3, 1981. Its title is the Veterans' Health Care, Training, and -Small Business Loan Act of 1981 (P.L. 97-72). �CRS- 2 IB80040 UPDATE-04/20/82 BACKGROUND AND POLICY ANALYSIS History During the summer of 1969, the first reports of human birth defects allegedly attributed to Agent Orange appeared in Vietnamese newspapers. Based on these allegations and the results of a study sponsored by the National Cancer Institute that showed that 2,4,5-T contaminated with TCDD caused birth defects in laboratory animals, the USAF stopped spraying 2,4,5-T in South Vietnam by early 1971. Although the Department of Defense maintains that only a limited number of U.S. military personnel can be positively identified as having been exposed to 2,4,5-T in South Vietnam (i.e., crews of aircraft that were used to spray herbicides), it is theoretically possible that large numbers of both military personnel (from the United States, South Vietnam, North Vietnam, Australia, and New Zealand) and civilians (especially South Vietnamese peasants) were exposed to 2,4,5-T through the USAF spraying program. A growing number of U.S. veterans who served in South Vietnam have begun to attribute the cause of various chronic ailments which they are now experiencing (especially nervous disorders, cancers, and birth defects in their offspring) to exposure to 2,4,5-T in South Vietnam, and many have filed claims with the VA for compensation. The VA has not yet awarded compensation to veterans for any claims related to 2,4,5-T exposure because of the lack of valid human data to prove a cause and effect relationship between exposure to 2,4,5-T and/or TCDD and specific health effects (except for chloracne). TCDD Contamination The industrial production "of 2,4,5-T always results in some TCDD contamination although TCDD levels can be reduced to about 0.01 parts per million (ppm) with current technology. Because it was not widely recognized until the late 1960s that 2,4,5-T could contain hazardous amounts of TCDD, manufacturers did not start reducing the level of TCDD in 2,4,5-T until the USAF was already winding down its herbicide spraying program. The average TCDD levels in the 2,4,5-T - containing herbicide mixtures used in South Vietnam were approximately 2 ppm in Agent Orange (which accounted for approximately 96% of the 2,4,5-T used in South Vietnam), approximately 32.8 ppm in Agent Purple, and 65.6 ppm in Agents Pink and Green (Agents Purple, Pink, and Green contained the remaining 2,4,5-T used in South Vietnam). The herbicides procured by the USAF were code named after the colored band that was placed around each 55 gallon drum in order to identify the contents. / Health Effects — Animal Data Although TCDD is well established as one of the most toxic chemicals known for acute (short-term) effects, there is no consensus in the scientific community over the -Chronic (long-term) effects on humans of exposure to low levels of TCDD (such as those levels found in the herbicides used in South Vietnam) . Statistically significant animal experiments have demonstrated that �CRS- 3 IB80040 UPDATE-04/20/82 2,4,5-T containing low levels of TCDD and/or TCDD alone have caused various tumors in mice and rats. A recently-released National Toxicology Program bioassay of TCDD confirms these earlier reports that TCDD is carcinogenic in some laboratory animals. Thymic atrophy (without a corresponding loss in immune function) and severe weight loss have been observed in many species after TCDD exposure. In some species, acute exposure to TCDD can cause liver damage. Birth defects such as cleft palate and kidney abnormalities have been reported in baby mice when the mothers were exposed during pregnancy. A National Toxicology Program animal study of male reproductive effects of exposure to TCDD, however, has failed to reveal a statistically significant increase in reproductive abnormalities in TCDD-exposed animals or birth defects in the TCDD-exposed male animals' offspring. Although there is some experimental evidence that TCDD may cause mutations (changes in the cell's genetic material that may produce birth defects in as-yet-unconceived offspring), these experiments have been few, they have been done mainly on non-mammalian species or in vitro (in test tubes), and they have basically been inconclusive. Some investigators feel that humans are less sensitive than animals to the toxic effects of TCDD. There is wide variation of" responses to TCDD among different species, and the mechanisms of its toxicity and metabolism are not understood. More work needs to be done to clarify whether human exposure to TCDD can produce the same health effects with the same potency as those observed in animal studies. Health Effects. -- Human.TData. If a cause and effect relationship is to be scientifically established between human exposure to a chemical and chronic health effects, a study which meets the following minimum criteria must be conducted to prove that such a relationship exists: a group of people (the "study group") must be identified that has already been exposed to the chemical under study (it would help to know the level of exposure); this study group must be large enough to detect chronic effects with statistical significance (to find an effect that occurred in 1 out of 100 people, one would need to examine at least 100 people); a control group must be found that ideally would differ from the study group only by never having been exposed to the chemical under study (thus, any differences in chronic health effects between the study and control groups could be attributed only to exposure to the chemical under study); and, due to the long latency period for many chronic effects, the study and control groups must be followed for as many years after exposure as it takes for the chronic effects to show up (i.e., in carcinogenicity studies, subjects must be followed for a minimum of 10 to 20 years after exposure to the suspect carcinogen). These exacting criteria are not met by most of the studies that have explored the relationship between human exposure to TCDD and/or 2,4,5,-T and subsequent health effects. Only for chloracne has such a cause and effect relationship been well established. Workers who have been exposed to TCDD and/or 2,4,5-T in industrial explosions or who have had other occupational exposure are frequently found to have a skin condition known as chloracne — which resembles normal acne except that it is caused by chemical exposure. Chloracne can appear from weeks to months after initial exposure and while mild cases (blackheads) may clear in a matter of months, severe cases (inflammatory lesions and scars) may last up to 30 years after exposure has ceased. While the severity of chloracne is not thought to correlate precisely with the intensity or duration of exposure to TCDD and/or 2,4,5-T, chloracne is associated so �CRS- 4 IB80040 UPDATE-04/2'0/82 closely with exposure that some scientists argue that patients who have not exhibited chloracne are unlikely to have suffered other toxic effects of TCDD and/or 2,4,5-T exposure. Studies of these exposed workers have also indicated a variety of other health problems. For example, the United States Air Force Technical Report on the Toxicology, Environmental Fate, and Human Risk of Herbicide Orange and its associated Dioxin (1978) listed a number of symptoms, signs, or disorders that had been reported after occupational exposure to TCP (trichlorophenol, 2,4,5-T's precursor), 2,4,5-T, or TCDD (see Appendix). As noted, these studies, which reported symptoms associated with human exposure to dioxin, were not conducted in such a way as to prove a cause-and-effect relationship between exposure to TCDD and/or 2,4,5-T and any of these effects, but they may be indicative of such a relationship. Several of the above studies have focused on investigating cancer rates among exposed workers. These studies do not show a clear cause/effect relationship between carcinogenicity associated with exposure to TCDD and/or 2,4,5-T because very few exposed workers (with the exception of those in Nitro, West Virginia) have been followed for more than ten years (the latency period for most cancers being 15 to 40 years after exposure) and the results have been equivocal. However, they support a continuing suspicion and indicate a need for further study. When the scientific panel of the Interagency Work Group on Phenoxy Herbicides reviewed five research papers by European scientists, it concluded that despite the studies' limitations, they do "show a correlation between exposure to phenoxy acid herbicides and an increased risk of some forms of cancer." A soft-tissue "sarcoma study has been proposed that will be conducted jointly by the Armed Forces Institute of Pathology and the National Cancer Institute. Studies that have been conducted in non-industrial settings have not been able to prove a cause and effect relationship between exposure to TCDD and/or 2,4,5-T and specific health effects. The National Academy of Sciences (NAS) was directed by Congress P.L. 91-441, sec. 506 (c) to conduct a study on the effects of herbicides in South Vietnam, including health effects. This NAS study, as well as at least three other similar studies that were conducted in South Vietnam during the early 1970s, were unable to find adequate data upon which to reach any conclusions concerning a causal effect between exposure to herbicides and any health effects, including birth defects. An explosion in a Hoffman-LaRoche chemical plant in Seveso, Italy in July 1976 caused thousands of people to be exposed to varying doses of TCDD as a toxic cloud drifted across the Italian countryside in a cone-shaped pattern about a mile long and half a mile wide. Some 5400 people lived in the two zones most directly affected, with an additional 40,000 people potentially exposed. Animals began to die 2 to 3 days after the incident with over 1,100 animals killed by direct exposure to TCDD. Over 700 people were evacuated from their homes. Chloracne was reported in 187 people, mostly children, and it tended to heal rapidly. Long-term human health effects of exposure to TCDD at Seveso are still being studied. Preliminary findings reported in 1979 by Hoffman-LaRoche revealed that Seveso residents had suffered liver damage but that there was no permanent breakdown in liver function. They also reported that rates of spontaneous abortions, fetal malformations, congenital defects, chromosome aberrations, reactions to infectious disease, and morbidity and mortality were not affected by TCDD exposure. As reported by the American Medical Association's Council on Scientific Affairs, "The most recent progress report on the long-term epidemiologic survey of the residents of the Seveso area emphasizes the preliminary nature of their �. . CRS- 5 IB80040 UPDATE-04/20/82 findings and reiterates the conclusions of prior investigators. Except for the skin, no organs or body functions were impaired. No derangement of gestation, no fetal lethality and loss, no gross malformations-, no growth retardation at term and no cytogenetic abnormalities have yet occurred." Health effects of domestic use of 2,4,5-T have been kept under surveillance by various Government agencies for some years. In April 1970, the Departments of Agriculture, Interior, and Health, Education and Welfare jointly announced the suspension of certain uses of 2,4,5-T following studies indicating that it was a teratogen. On Apr. 21, 1978, the Environmental Protection Agency (EPA) issued a Rebuttable Presumption Against Registration (RPAR) on 2,4,5-T, finding that the herbicide had exceeded certain risk criteria and inviting comments from interested parties. The RPAR was based on toxicological data from animal studies showing a correlation between 2,4,5-T exposure and cancer and birth defects. One of the comments received was from Alsea, Oregon, claiming that there was a high incidence of miscarriage among area women following spraying of the local forests with 2,4,5-T. EPA investigated this claim and reported its conclusion that the incidence of spontaneous abortion over a 6-year period in Alsea was higher than the rates in two other regions of Oregon that had lower rates of 2,4,5-T usage. Based on the combination of evidence from the animal studies and the Alsea study, EPA announced the emergency suspension of the domestic use of 2,4,5-T on forests, pastures, and rights-of-way on Feb. 28, 1979. The Alsea study has been criticized on methodological grounds by various groups, and its results are rejected by a number of writers. EPA hearings on cancellation of 2,4,5-T began in June 1979. On Mar. 24, 1981, EPA and Dow Chemical requested a recess in the hearing to discuss the possiblity of negotiating a settlement. The recess has been extended while the negotiations continue. Herbicide Spraying in Vietnam Approximately 107 million pounds of herbicides were aerially disseminated on 6 million acres of South Vietnam (an area about the size of Connecticut) from January 1962 to February 1971. Approximately 276,000 gallons of Agents Green, Pink, and Purple were sprayed in South Vietnam prior to 1965 when they were replaced by Agent Orange. Approximately 11 million gallo.ns of Agent Orange were then sprayed in South Vietnam — making it the most widely used herbicide of the war. Ninety percent of Agent Orange was sprayed on 2.9 million acres of inland forests and mangrove forests for defoliation, 8% was sprayed on enemy crops for crop destruction, and the remaining 2% was sprayed around base perimeters, cache sites, waterways, and communications lines. The Air Force continued to operate its herbicide spraying program in South Vietnam until the late 1960s when the National Cancer Institute released results of an animal bioassay that showed 2,4,5-T to be teratogenic and/or fetotoxic in rodents, and newspapers in South Vietnam started reporting health problems among the rural populations who had been exposed to such herbicides. The Air Force first restricted the use of Agent Orange to areas remote from populations in October of 1969, then stopped all airplane spraying of Agent Orange in early 1970 and all helicopter spraying of Agent Orange by 1971. All remaining herbicide stocks were gathered and stored at either Gulfport, Mississippi or Johnston Island in the Pacific until they were incinerated at sea in 1977. The following table outlines major military projects involving handling of Agents Orange, Purple, Pink, or Green in South Vietnam. the �CRS-6 IB80040 UPDATE-04/2'0/82 MILITARY PROJECTS INVOLVING AGENTS ORANGE, PURPLE, PINK, OR GREEN PROJECT DATES DESCRIPTION AGILE 1960-68 Selection of herbicides., and development and evaluation of defoliation techniques.

Each of these projects involved some human exposure to the herbicide 2,4,5-T and its contaminant, TCDD. The difficulty lies in determining who may have been exposed and at what level. �CRS-7 IB80040 UPDATE-04/20/82 Personnel Exposed The early trials that were conducted in South Vietnam to improve aircraft spray systems (1960 to early 1962) were conducted by USAF personnel assigned to the Special Aerial Spray Flight Division, Langley AFB, Va. (USAF personnel engaged in the herbicide program did not receive permanent change of station assignments to South Vietnam until 1964 -- thus making it more difficult to track personnel who may have been exposed to herbicides). During late 1962 and early 1963, the Crops Division at Fort Detrick and the USAF Armament Laboratory at Eglin Air Force Base, Florida were involved in efforts to provide improvements in spray system components in support of Operation RANCH HAND. Most of the personnel involved in the actual handling of herbicide drums were Vietnamese. However, a USAF flight mechanic or crew chief was responsible for ensuring that the aircraft were properly loaded and that the spray systems were functional. Each herbicide aircrew consisted of a pilot and a copilot (both usually officers) and a flight mechanic/spray unit operator (usually enlisted). The aircrews were frequently joined by South Vietnamese and U.S. observers. As noted in a USAF report, "within the aircraft, it was not uncommon to have herbicide leakage from around the numerous hose connections joining the spray tank and pumps with the wing and aft spray booms. In hot weather, the odor of herbicide within the aircraft was decidedly noticeable." The USAF has data on 6,542 herbicide spraying missions that took place between August 1965 and February 1971 on its "HERBS" computer tape. These data were compiled on a mission-by-mission basis from reports and files in various commands and offices in South Vietnam and the United States. The HERBS tape contains the following data for each mission: date; mission number; location; province and UTM coordinates; type of herbicide (basically, Agents Orange, White, or Blue); quantity of herbicide; area covered; purpose of mission (defoliation, crop destruction, etc.); and type of aircraft (plane or helicopter). The NAS used the HERBS tape in its evaluation of the effects of herbicides on South Vietnam. After evaluating the HERBS data, the NAS concluded that the HERBS tape accounted for approximately 86% of all herbicide operations in South Vietnam and that "despite certain recognized deficiencies," the HERBS tape is "a reliable source for an assessment of the major part of the herbicide operation in South Vietnam" and "is the best and in fact the only available comprehensive computation of the major part of the herbicide operations conducted in the Vietnam war." When the DOD suspended all use of 2,4,5-T in South Vietnam, the USAF was left with an inventory of 2.22 million gallons of unused Agent Orange (1.37 million gallons which had been shipped to South Vietnam and 0.85 million gallons which were waiting to be shipped at the Naval Construction Battalion Center at Gulfport, Mississippi). In April 1972, the 1.37 million gallons of Agent Orange were moved from South Vietnam to Johnston Island in the Pacific Ocean for storage. The total amount of TCDD in the remaining Agent Orange stock was approximately 44.1 pounds. Problems began to arise in both locations as drums reportedly began to leak and the USAF expressed concern over further leakage problems that could occur if a tornado hit the Mississippi site or if a typhoon hit the Pacific site. After exploring a number of options, the USAF decided to dispose of the Agent Orange by burning it at high temperatures at sea on the Dutch incinerator ship named the "Vulcanus." The Agent Orange was drained from the drums at each site and �CRS- 8 IB80040 UPDATE-04/20/82 transferred to the Vulcanus. The empty drums were then rinsed with diesel fuel and crushed. The rinse fluid was combined with the Agent Orange for incineration at sea. A total of 15,480 drums of Agent Orange were processed at the Mississippi site between May 24, 1977, and June 10, 1977, by approximately 110 USAF officers/technicians from the five Air Logistics Centers of the Air Force Logistics Command (located at Kelly AFB Texas; Hill AFB, Utah; Warner Robbins AFB, Georgia; Tinker AFB, Oklahoma; and McCellan AFB, California). A total of 24,795 drums of Agent Orange were processed at the Johnston Island site between July 27, 1977, and Aug. 23, 1977. Approximately 100 civilian employees hired by a contractor performed the dedrumming process. At both the Johnston Island and Mississippi sites, workers were provided with daily changes of work clothes and some with protective clothing. The Agent Orange was incinerated at sea in the period from July to September 1977. Results of industrial hygiene studies conducted at the time of the disposal operation by the U.S. Air Force (Gulfport) and the Battelle Memorial Institute (Johnston Island) revealed no immediate adverse health effects among the personnel involved in the operation. Department of Defense, Efforts The USAF has stated that it can now identify 1,264 servicemen who were directly exposed to Agent Orange as they handled herbicide., containers and flew spraying missions in South Vietnam. The Air Force has initiated a health effects study of Air Force personnel involved in operation "Ranch Hand," who sprayed Agent Orange in Vietnam. The Department of Defense (DOD) believes that these individuals had at least 1000 ti-mes more exposure .to Agent Orange than the average ground troops. The epidemiological study will try to determine whether a causal relationship can be established between exposure to the 2,4-D/2,4,5-T mixture and long-term health effects. Although the study was originally scheduled to begin in October 1979, peer review of its protocols forced delays. The University of Texas School of Public Health, the U.S. Air Force Scientific Advisory Board and the Armed Forces Epidemiological Board reviewed the study protocols and recommended modifications. Then the Air Force asked the National Academy of Sciences (NAS) to review the protocols. On May 6, 1980, the NAS announced recommendations that the scope and duration of the study be expanded to increase the likelihood of obtaining definitive data. NAS also expressed concern about the public perception of credibility and impartiality of a study conducted internally by the Air Force. The Interagency Work Group's Scientific Panel, however, has recommended that the study, as designed by the Air Force, be conducted because, despite its limitations, it provides "a focus as to the type of health effects that may possibly occur in other (ground troop) personnel." The Ranch Hand study is proceeding in several phases and will continue for 20 years. The first phase consists of a detailed medical history questionnaire, which has been administered to the Ranch Handers in their homes by trained interviewers from Louis Harris and Associates. A carefully matched control group, selected from military records held by the Air Force, has also been interviewed. The first data from the questionnaire should be available by mid-summer 1982. Also underway is the second phase of the study, a 3-day series of physical examinations, including a battery of psychological tests, which will be given to both the study group and the controls. The contractor for this phase is Kelsey-Seabold of Houston. The exams are scheduled to be completed by September 1982, with preliminary findings available 2 to 3 months later. Follow-up exams will be conducted at 1, 3, 5, 10, and 20 years. A mortality analysis on the Ranch Hand group is �, , , CRS- 9 IB80040 UPDATE-04/20/82 in progress at the Air Force School of Aerospace Medicine, with data anticipated around August 1982, and a mortality tracking program will be continued throughout the study. Information on the health status of the veterans, as shown by the questionnaires and the physical examinations, will provide data for a morbidity analysis. Many of the veterans who have filed claims with the VA for compensation for health effects caused by exposure to TCDD in South Vietnam did not hold jobs that caused direct exposure to 2,4,5-T. They claim that their exposure occurred indirectly either by being sprayed with overhead planes (although substances other than herbicides were also sprayed from planes) or by being exposed to 2,4,5-T in the environment. According to the DOD, military personnel did not usually enter areas sprayed with Agent Orange until 4 to 6 weeks after treatment. However, a recent General Accounting Office investigation concluded that a large number of Marines in the I Corps section of Vietnam from 1966-1969 were in, or close to, areas sprayed with Agent Orange on both the day of spraying and within 4 weeks afterward. Some Army units were also close to Agent Orange spraying. The Department of Defense has recently made progress in identifying ground troops that may have been exposed to Agent Orange. Two Army and one Marine battalion - 31st Engineer Battalion, 2050 troops; 1st Squadron, 9th Calvary (Air Mobil), 2300 troops and 3rd Battalion, 1st Marines, have been identified as being in areas of Agent Orange operations. Exact numbers, locations, and identities of individuals who may have been sprayed are impossible to determine. Veterans' Problems and Veterans^ .Administration E_f_fO'rts The first reports of veterans' concerns over health effects of exposure to 2,4,5-T began to appear in late 1977 and early 1978, following media coverage of several veterans' claims. Veterans have associated a number of illnesses with exposure to 2,4,5-T, including skin conditions, fatague, nervousness, numbness in extremities, vision and/or hearing impairments, birth d'efects in offspring, reduced libido, miscarriages, impotency, respiratory problems, gastro-intestinal tract disturbances, and various cancers, as well as a variety of other illnesses. As of Apr. 1, 1982, the VA had received 13064 claims for damage reportedly related to in-service exposure to herbicides? 2986 claims have been made due only to exposure to the herbicides and not for any specific condition; 10078 claims have been filed for specific conditions related to herbicide exposure, but 3469 of these have not had the diagnosis con-firmed by medical authority. Of the 6609 claims with a confirmed diagnosis, 923 (13.7%) have been allowed for reasons other than Agent Orange exposures and 5686 (86.3%) have been denied. Approximately 93% or 858 of the total 923 claims allowed were for service-connected skin conditions, and the remaining 7% or 65 claims were allowed for cancer, psychiatric and neurological conditions, and various other miscellaneous disabilities. The 5686 claims denied fall into the following categories (many claims have more than one claimed diagnosis): 3055 for various skin conditions; 2335 for nervousness, headache, or fatigue; 886 for paralysis or numbness; 751 for gastro-intestinal or genito-urinary conditions; 399 for various malignancies; 356 for impaired sexual activity; 394 for eye, ear, nose, and throat conditions; 274 for lung conditions; 227 for cardiovascular conditions; and 137 for miscellaneous conditions. The VA has not awarded compensation for the claims of chronic illnesses related to Agent Orange exposure because of the lack of valid human data to prove a �CRS-10 IB80040 UPDATE-04/20/82 cause and effect relationship between exposure to a 2,4,5-T/2,4-D mixture and/or TCDD and specific chronic health effects. Previously, the difficulty of determining which veterans' were or were not exposed to Agent Orange was also a factor in denying compensation, but more recently the VA has conceded exposure for all veterans who were in Vietnam. The VA is maintaining a registry of all Vietnam veterans who have come to VA hospitals and health care facilities expressing concern about possible herbicide-related health problems. Each such veteran, whether experiencing any health problems or not, is given a physical examination; currently, some 2700-2800 exams are being conducted each month. Data from all the exams is being computerized into a central Agent Orange Registry in addition to the individual records being maintained at the local VA facilities. As of Mar. 25, 1982, 81,670 veterans had received the initial exam, and about 61,000 of the records had been coded into the computer. Information from the registry is being analyzed to determine if the veterans have an increased rate of any particular diseases. Thus far, nothing unusual or unexpected has turned up. Treatment of any health problems uncovered by the exams is handled under normal VA procedures regarding service-connection, ability to pay for medical care, etc., with the exception that special guidelines have been issued for the handling of conditions possibly related to Agent orange. In the Federal Register of Dec. 2, 1981, pursuant to Public Law 97-72, the VA issued guidelines for use by its physicians to "assist them in making determinations in individual cases as to whether a disability may have been caused" by exposure to Agent Orange. Even though treatment may be given for some conditions, the VA specified that "In accordance with congressional intent, a determination to furnish care under this authority does not establish that the condition for which medical care is provided is service-connected" for purposes of compensation or vocational rehabilitation eligibility. Three additional VA activities on Agent Orange include participation in the tissue registry, the Chloracne Task Force, and investigations into TCDD residues in body fat tissue of veterans. When VA facilities perform surgery or autopsies on Vietnam veterans, tissue samples are taken and sent to the Armed Forces Institute of Pathology where a special tissue registry is being maintained. Examination of approximately 800 specimens has so far shown no significant clustering of tumors or other particular disease features. The Chloracne Task Force was established in response to a congressional request to sift out those cases of skin conditions that either resemble or are truly Chloracne. Those veterans whose medical records show a definite possibility of Chloracne will be invited to come to non-VA clinics for re-examination by dermatologists who have an expert knowledge of the disease. The VA has conducted a study to determine if TCDD can be detected in the body fat tissues of Vietnam veterans at any higher levels than in veterans who were not in Vietnam. Dioxin in body fat is measured in parts per trillion, levels which are at the technological limits of available detection methods. The test requires surgical removal of tissue from the abdomen and chemical analysis of the sample on gas chromatography/high resolution mass spectrometry instruments. The results of the study were inconclusive, and the VA has decided that the reliability of the procedure is not sufficient to warran-t its use in attempting to verify dioxin exposure. An additional problem is that dioxin contamination is so ubiquitous (from domestic herbicide use and from its formation in municipal incinerators) that it may likely be found in everyone's fat tissue. As mandated in P.L. 96-151, the Veterans' Affairs Amendments, the VA is currently preparing to perform an epidemiological study of Vietnam veterans exposed to Agent Orange. Although the study's protocol has been developed �CRS- 11 IB80040 UPDATE-04/20/82 and validated by an independent group, the VA will perform the testing and collect the data, with oversight by a non-VA scientific committee. Procurement of an independent contractor for the study's protocol was delayed for 14 months by a protest filed by the National Veterans Law Center (NVLC) . The NVLC alleged that not only was the .VA violating procurement law, but also the study as currently contemplated did not comply with the requirements of P.L. 96-151. On Feb. 2, 1981, the General Accounting Office concluded its investigation and denied the NVLC protest. On May 5, 1981, the VA announced the awarding of a contract to the University of California at Los Angeles (UCLA) School of Public Health for the design of the epidemiological study. UCLA submitted its first draft of the protocol to the VA in August 1981; it was peer-reviewed by the VA Advisory Committee on Health-Related Effects of Herbicides, by the Office of Technology Assessment, and by the Science Panel of the Agent Orange Working Group. All the review groups judged the draft protocol to be inadequate and not in compliance with the contract. UCLA has since modified the protocol, expanding on problem areas and incorporating the suggestions of the review groups; its final submission to the VA is due April 29, 1982. As with the Ranch Hand study, this epidemiological study will have two main parts: a questionnaire on health status and medical and occupational history, and a physical exam with laboratory workup. The study group will be 18,000 veterans, divided into 3 cohorts of 6000 each. Two of the cohorts will have had Vietnam service, and will be distinguished as having a high or a low likelihood of herbicide exposure. The third cohort will be veterans with non-Vietnam military service. Inclusion of the third group will generate data about the health effects of Vietnam service in addition to the information expected about herbicide-related health effects. The study will commence with a pilot project to field test its procedures.and the questionnaire. P.L. 96-151 also mandated the VA to conduct a comprehensive review and scientific analysis of the worldwide literature on Agent Orange and other phenoxy herbicides. JRB Associates prepared the review under contract, and the VA published the 2-volume study in October 1981. The VA is now preparing to contract for an update to the literature review, to reflect new reports and data -that have appeared. The Interagency Work Group on Phenoxy Herbicides and Contaminants, established in December 1979, recommended that the Centers for Disease Control (CDC) perform a case-control study to see if there is an increased incidence of specific malformations in children of Vietnam veterans. The population to be studied is a group of 7500 children who have birth defects and who are registered in CDC's Birth Defects Program (in operation since the late 1960s). Information on the families of these children, gained by extensive interviews and questionnaires, will be compared with that for 300 normal controls. The data will be analyzed to see what risk factors in the parents' lives, including military service in Vietnam, may be related to increased incidence of malformations in their children. CDC has completed a pilot study on a representative sample of the two groups to test the questionnaire and the procedures for finding the families. The main study will be started in late April 1982, and a preliminary report on the issue of Vietnam service is expected in the fall of 1983. Detailed analysis of the data on all risk factors will take several years to complete. On Sept. 22, 1980, the Work Group held its first public meeting to discuss problems and proposals related to exposure to herbicides. On Jan. 19, 1981, the Secretary of Health and Human Services established the "Advisory Committee on Special Studies Relating to the Possible Long-Term Health Effects of Phenoxy Herbicides and Contaminants" to advise the Secretary and �CRS- 12 IB80040 UPDATE-0'4/20/82 the Chair of the Interagency Work Group on Herbicides concerning the Advisory Committee's oversight of the conduct of the Ranch Hand Study being conducted by the Air Force. In its seventh report to the White House, the Work Group's Scientific Panel concluded that: While it is difficult to accept logically that a single causative factor -- Herbicide Orange -- could be responsible for such a diverse set of health effects as alleged by Vietnam veteran claims to the VA , there is no definitive evidence that permits selective exclusion of some of these illnesses. Further, it is possible that some of these health effects are occurring as a consequence of Vietnam^ service but not due to exposure to Herbicide Orange. The Science Panel is not aware of any data that suggest a modification of its previous recommendation that the •focus of a study of Vietnam veterans should be broadened to consider Vietnam service as the exposure factor rather than focus solely on Herbicide Orange exposure.... The Science Panel is in receipt of data which indicate that there is at best a remote chance of accurate identification of specific ground troops who were exposed to Herbicide Orange.... The Panel is therefore of the opinion that design of a scientifically valid Herbicide Orange study of ground troops may not be possible. If the focus of a study of Vietnam veterans is broadened to consider Vietnam service as the exposure factor, a study of ground troops is necessary and a scientifically valid study can be designed. On July 17, 1981, the Interagency Work Group was renamed and its membership expanded. Now called the Agent Orange Working Group, it is part of the Cabinet Council on Human Resources. The Department of Health and Human Services is the lead agency. Because the VA currently recognizes only chloracne as a human health effect that can be proven to be caused by exposure to 2,4,5-T, veterans may have difficulty being compensated for even those effects for which there is strong animal evidence (i.e., cancer and birth defects caused in utero which are those birth defects that cannot be caused by the father and require the mother and fetus to be exposed during the actual pregnancy). Veterans who claim compensation for health effects which are not supported by strong animal data (i.e., mutations -- which could cause genetic defects in the father's sperm that would affect children conceived after exposure) may have an even tougher case to argue. The veteran's question then becomes: How much evidence is required to prove the right to compensation? On whom does the burden of proof lie (the veteran or the VA)? .If more evidence is needed, who will generate it? And finally, what constitutes fair treatment of veterans while the necessary data are being gathered? Congressional Action of the 96th Congress The 96th Congress responded to the problems of establishing a cause and effect relationship between veterans' exposure to herbicides in South Vietnam and the various health problems they are now experiencing by holding hearings and enacting legislation. �CRS- 13 IB80040 UPDATE-04/20/82 The Subcommittee on Oversight and Investigations, of the House Committee on Interstate and Foreign Commerce held hearings on June 24 and 25, 1979, to hear testimony from veterans who allegedly have been affected by herbicide exposure and from the Veterans Administration regarding its efforts to unequivocally determine the relationship between herbicide exposure and health effects. The Subcommittee on Medical Benefits and Facilities of the House Committee on Veterans' Affairs held two sets of hearings on the hazards associated with TCDD, veterans' complaints of health effects associated with Agent Orange exposure, and Veterans Administration's efforts to resolve the Agent Orange problem. The Senate Veterans' Affairs Committee also held hearings to Agent Orange problem. examine the As a step to gain access to records to locate veterans who may have been exposed to herbicides in-service, Title V of H.R. 2282, the Veterans' Disability Compensation and Survivors' Benefits Amendments of 1979, requires the Director of the National Institute for Occupational Safety and Health, upon request by the VA (or other appropriate agency) to request the current mailing address from the Internal Revenue Service of persons whom the VA certifies may have been exposed to occupational hazards. H.R. 2282 was passed in lieu of its companion bill, S. 689, and became Public Law 96-128 on Nov. 28, 1979. Title III of H.R. 3892, the Veterans' Affairs amendments, directs the Veterans Administration to conduct an epidemiological study of the long-term health effects on individuals from exposure to dioxins in Vietnam, upon the Office of Technology Assessment's (OTA) approval of its protocol. Its companion bill, S. 1039, was incorporated in H.R. 3892 as an amendment, and the measure was enacted by Congress and signed by the President on Dec. 20, 1979 (P.L. 96-151) . If enacted, S. 2096 would have directed the Secretary of Health, Education, and Welfare (now, Health and Human Services) to undertake an epidemiological study to determine the long-term adverse human health effects associated with exposure to dioxins produced during the manufacture of phenoxy herbicides. This bill proposed to investigate the long-term health effects of exposure to dioxins, in general, not just to Agent Orange. As similarly incorporated in H.R. 3892, S. 2096 would have required that the study's protocol be approved by the Congressional Office of Technology Assessment. This bill was presented to the President on Dec. 21, 1979, and vetoed by him on Jan. 2, 1980. President Carter vetoed the bill because the White House counsel believed that such a procedure violated the separation of power between the legislative branch and the executive branch. He did not feel that the Department of Health and Human Services' study protocol should be subject to approval by a congressional agency. Title X of H.R. 5288, the Veterans' Rehabilitation Program and Veterans' Educational Assistance Program would have directed the Secretary of Health and Human Services to conduct a study of veterans and other groups exposed to the herbicide known as "Agent Orange" to determine if there may be adverse health effects associated with such exposure. Like H.R. 3892 (P.L. 96-151) and S. 2096, the bill called for OTA approval of the study's protocol. The bill also would have required the Secretary of Health and Human Services to coordinate its efforts with other studies in the Federal Government. During the debate on S. 1188, its companion bill, the Disabled Veterans' Rehabilitation Act, the Senate adopted an amendment offered by Senator �CRS-14 IB80040 UPDATE-04/20/82 Cranston to expand the study on health effects of exposure to Agent Orange to include other factors related to service in Vietnam. The Senate also adopted an amendment offered by Senator Heinz requiring the VA to promulgate regulations regarding guidelines to resolve veterans' disability claims based on exposure to Agent Orange. The ' amendments were striken by the House because they were considered to be "non-germane" to the primary focus of the bill.

H.R. 8238 (Independent Agent Orange Study) would have directed the Veterans Administrator to request the National Academy of Sciences to conduct a study on veterans exposed to Agent Orange. H.R. 8300 would have expanded the scope of the Agent Orange study currently being coordinated by the VA and would have established deadlines for promulgating regulations related to Agent Orange exposure claims. These bills received no action. LEGISLATION P.L. 97-72, H.R. 3499 Veterans' Health Care, Training and Small Business Loan Act of 1981.
