Air Force aircraft returned from Vietnam identified as postwar source of Agent Orange contamination

From 1971-1982 Air Force reservists, who flew in about 34 dioxin-contaminated aircraft used to spray Agent Orange and returned to the US following discontinuation of the herbicide spraying operations in the Vietnam War, were exposed greater levels of dioxin than previously acknowledged, according to a study published in Environmental Research."These findings are important because they describe a previously unrecognized source of exposure to dioxin that has health significance to those who engaged in the transport work using these aircraft," says lead investigator Peter A.
