Abstract : We attempted to quantify potential individual exposures to Agent Orange (to include its trace dioxin contaminant) experienced by persons (e.g., aircrew, passengers) who worked on or travelled in UC-123 aircraft between 1972 and 1982. After an extensive search of the scientific and technical literature, review of the available sampling data, an attempt to employ modeling to extrapolate exposures, and an assessment of the feasibility of conducting epidemiological studies, we concluded the existing information and data are inadequate to allow for accurate quantitative estimates of individual exposures. We then considered the probability of harmful exposures in UC-123 exposure groups (i.e., occupational and general populations) based on the nature and environment of the material sampled, the expected characteristics of dried Agent Orange residue, and the conditions of general exposure. At this time, we conclude that the discernable information suggests the potential Agent Orange exposures for both groups (who were in contact with the UC-123 aircraft between 1972 and 1982) were unlikely to have exceeded acceptable regulatory standards or to have predisposed persons in either group to experience future adverse outcomes.
