AGENT ORANGE

mixture of herbicides that U.S. military forces sprayed in Vietnam from 1962 to 1971 during the Vietnam War for the dual purpose of (1) defoliating forest areas that might conceal Viet Cong and North Vietnamese forces and (2) destroying crops that might feed the enemy. The defoliant, sprayed from low-flying aircraft, consisted of approximately equal amounts of the unpurified butyl esters of 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T). Agent Orange also contained small, variable proportions of 2,3,7,8-tetrachlorodibenzo-p-dioxincommonly called dioxinwhich is a by-product of the manufacture of 2,4,5-T and is toxic even in minute quantities. About 50 million litres (13 million gallons) of Agent Orangecontaining about 170 kg (375 pounds) of dioxinwere dropped on Vietnam. Among the Vietnamese, exposure to Agent Orange is considered to be the cause of an abnormally high incidence of miscarriages, skin diseases, cancers, birth defects, and congenital malformations (often extreme and grotesque) from the 1970s to the '90s. Many U.S., Australian, and New Zealand servicemen who suffered long exposure to Agent Orange in Vietnam later developed a number of cancers and other health disorders. Despite the difficulty of establishing conclusive proof that their claims were valid, U.S. veterans brought a class-action lawsuit against seven herbicide makers that produced Agent Orange for the U.S. military. The suit was settled out of court with the establishment of a $180,000,000 fund to compensate some 250,000 claimants and their families. Separately, the U.S. Department of Veterans Affairs awarded compensation to about 1,800 veterans.
