Agent Orange was one of the weed-killing chemicals used by the U.S. military in the Vietnam War. It was sprayed to remove leaves from trees that enemy troops hid behind. Agent Orange and similar chemicals were known as “herbicides.” Agent Orange was applied by airplanes, helicopters, trucks and backpack sprayers.
In the 1970’s some veterans became concerned that exposure to Agent Orange might cause delayed health effects. One of the chemicals in Agent Orange contained small amounts of dioxin (also known as “TCDD”), which had been found to cause a variety of illnesses in laboratory animals. More recent studies have suggested that dioxin may be related to several types of cancer and other disorders.
