L. Young and B. C. Wolverton Air Force Armament Laboratory (ATMA) Eglin Air Force Base, Florida Determination of arsenic in soils by atomic absorption techniques does not differentiate organic arsenic (e.g., cacodylic acid) from an inorganic form of arsenic (e.g., arsenic trioxide). Since cereal crops arc more sensitive to organic forms of arsenic than to inorganic forms, a bioassay technique was developed. Cacodylic acid or arsenic trioxide, expressed as ppm elemental arsenic, was uniformly mixed (V/V) with soil at rates of 0, 5, 10, 20, 40, CO, 80, 100, 120, and 160 ppm, A Gulf Coast Flatwood soil consisting of 93.9-0 sand, 3.7% silt, 2.4% clay, and 0.3% organic matter was used for all bioassay determinations. Ten seeds of sorghum, Sorghum .vulgarc L. var. Mor-Su, were planted per cup and the experiment replicated five times. All cups were maintained under greenhouse conditions. Number of seeds germinated and height (cm) of all plants (soil surface to tip of longest blade) were obtained after 10 days. Statistical analysis of the data indicated that height (in cm on a per cup basis) responded to a concentration range of 5-20 ppm As from cacodylic acid and 20-120 ppm As from arsenic trioxide. The average height of sorghum at 20 ppm As from cacodylic acid was 0.2 cm, while average height for 20 ppm As from arsenic trioxide was 5.2 cm. Average height of control plants was 6.2 cm. The multiple regression coefficients were .96 and .89, respectively. Equations for predicting concentration of arsenic Were as follows: 1.331 - O.QSh Where T » ppm As from cacodylic acid h = average height (cm) of sorghum (per treatment) Std, Error of Bst. • 0,076 AND Log10T = 2.041 - 0.093h Where T - ppm As from As^O, h = average height (Cm) of sorghum (per treatment) Std. Error of Est. = 0.123 Since there was virtually no overlap in the effective concentration range of the two arsenicals, an approximate value (ppm) could be obtained for the form of arsenic present when combined with data for total arsenic from atomic absorption analysis. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Young Office of Science and Technology Policy Executive Office of the President Washington, D.C. 20506 The environmental contaminants polychlorodibenzo-p-dioxins (PCDDs), and especially the 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), have received extensive public attention for more than 12 years. Dioxins are contaminants formed during the synthesis of chlorophenols and during low temperature combustion of wastes containing chlorinated precursors. Dioxins are at the center of controversies over (1) the use of Agent Orange in Vietnam and the health of veterans, (2) the use of trichloro-and pentachlorophenolic-derived products and (3) the development of technology for the incineration of municipal and industrial wastes. In response to the concerns over dioxins, and especially TCDD, mobilizations of resources have occurred within the private sector, academic community and state and federal governments. Many of the early efforts dealt with identifying sources of the contamination and elucidating the toxicology. More recently, the focus has been on understanding the chemistry, environmental fate and the mechanisms of toxic action of the dioxins. Industry scientists have been primarily responsible for conducting health studies of industrial populations exposed to TCDD and other dioxins as well as sponsoring many of the early toxicologic studies. The response of the Federal government has been through the coordination and funding of much of the basic long-term research including an impressive commitment to evaluating the human risk of exposure to TCDD. Indeed, this latter program encompasses scientific and financial resources from ten Federal agencies and includes White House oversight of 15 ongoing major human studies including five health surveillance studies and ten epidprniologic studies. The science policy implications of the massive research and remedial programs underway on dioxin are disturbing. To date, the Federal government has committed hundreds of millions of dollars and thousands of man-years to confirm that actual human exposure to dioxins is minimal and occurs primarily in "hot spots," and that the number of individuals exposed is very low. Moreover, the data collected to date are not able to associate chemical exposure to carcinogenesis, teratogenesis, or mutagenesis in man, yet these data neither impact proposed actions on clean-up (e.g. Times Beach) nor impedes Congressional action to legislate presumptive compensation. Finally, data obtained from combustion studies show that the production of dioxin is minimal and easily controlled with present technology, yet the fear of dioxin has paralyzed incineration technology and its application. The need for realistic risk assessments and the assignment of priorities for the allocation of resources are indicated. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Young, Office of Science and Technology Policy, Executive Office of the President, Washington, D.C. 20506 The highly toxic chemical 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD or dioxin) is a contaminant of products made from trichlorophenol and from low temperature incineration of wastes containing chlorinated precursors. Dioxin is at the center of controversies over (1) the use of Agent Orange in Vietnam and the health of veterans, (2) the use of 2,4,5-T herbicide in Agriculture, and (3) the development of technology for the incineration of muncipal and industrial wastes. It has been associated with the evacuation of human populations in Seveso, Italy; Times Beach, Missouri; and Love Canal, New York. The United States Government has initiated an extensive long-term research program to evaluate the impact of dioxin on human health. This program encompasses scientific resources from ten federal agencies. Risk assessments on dioxin are predicated on laboratory animal toxicologic data and on estimated bioavailability, but the reality of actual human exposure suggests that these assessments are too conservative. Moreover, questions remain as to whether science alone can resolve an issue that has attracted enormous societal interest. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Young Agent Orange Projects Office (1QA7B) Department of Medicine and Surgery Veterans Administration Washington, D.C. 20420 Long-term studies on the fate of TCDD have been conducted in five geographically different field locations throughout the United States. These studies have confirmed that although TCDD is very persistent in the soil environment, its movement is associated with wind and water movement of oontaminanted particles. Organisms, including man, that come in direct and intimate contact with contaminant particles become contaminated. A relationship exists between body burden levels of TCDD and the bioavailability of the environmental contamination. The significance of these observations to man is illustrated through the environmental toxicologic studies of the beachmouse, Peromyscus polionotus, a dominant inhabitant of an ecosystem that has been contaminated with TCDD for more than 15 years. * Abstract of a presentation to the Symposium "DIOXINS IN THE ENVIRONMENT", December 6, 1983, Michigan State University, East Lansing, Michigan. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

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.

Young * Department of Medicine and Surgery Veterans Administration Washington, D.C. 20420 Abstract of Presentation Weed Science Society of America Hyatt Regency Miami Miami, Florida February 8, 1984 *Current Address: Senior Policy Analyst for Life Sciences Office of Science and Technology Policy New Executive Office Building Room 5005 Washington, D.C. 20506 �Health Assessments of Herbicidest A Case Study of the Phenoxy Herbicides. 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.

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. For more about this collection, <a href="/exhibits/speccoll/exhibits/show/alvin-l--young-collection-on-a">view the Agent Orange Exhibit.</a> Text A resource consisting primarily of words for reading.
