Agent Orange is a chemical defoliant and during the Vietnam War more than 20 million gallons (80 million litres) of it were sprayed by the US military on the forests that ran along the border between Vietnam and Cambodia. The US aim was to disrupt North Vietnamese supply lines on the Ho Chi Minh Trail that ran through these forests. Agent Orange, however, contains Dioxin, an extremely toxic chemical that has caused widespread cancer and appalling birth defects.
I followed the research of Vietnamese oncologist Professor Ton That Tung, who, while based at the Viet Duc Hospital in Hanoi, had identified families in the north with no previous history of genetic abnormalities, and where mothers had never left their villages – but the husbands had been on Ho Chi Minh Trail and had been exposed to Agent Orange.
Getting in to Vietnam in 1980, just five years after the end of the war, was not a simple process, and it would not have been possible without the help of Madame Louise Vidaud du Plaud, an intrepid Frenchwoman who had escaped to England from Vichy France during WW2. In the 1960s during the Vietnam War she worked with an underground organisation in Saigon, still had many contacts and was able to get me a visa and access.
American servicemen exposed to Agent Orange during the war later received some compensation from the US government for their ongoing health issues.
The US Environmental Protection Agency, in its submission to the US administrator, stated, “It is impossible to ascertain a safe level of human exposure to Dioxin. The quality, quantity and variety of data demonstrating that the continued use of 2,4,5-T contaminated with Dioxin presents a risk to human health is unprecedented and overwhelming”. However, none of the Vietnamese victims of the chemical have received anything from the US.
Meanwhile, in the UK, despite health concerns, 2,4,5-T was widely available at that time. It was manufactured in Britain by Coalite Oil and Chemicals Ltd, until an explosion at a similar plant in Sevaso, Italy in 1976 exploded sending out a contaminating cloud of Dioxin. Debris from a previous explosion at Coalite’s plant in 1968 had been secretly buried after the blast killed one chemist and gave 79 workers Chloracne, a disfiguring skin disease.
The National Union of Agricultural and Allied Workers (NUAAW), now part of Unite the Union, campaigned to have the chemical banned and in 1979 it was withdrawn.
I have followed some of the cases that the NUAAW had highlighted as part of this campaign.
