This is a book about Dioxin, one of the most poisonous chemicals known to humanity. It was the toxic component of Agent Orange, used by the US military to defoliate huge tracts of Vietnam during the war in the 60s and 70s. It can be found in pesticides, plastics, solvents, detergents and cosmetics. Dioxin has been revealed as a human carcinogen, and has been associated with heart disease, liver damage, hormonal disruption, reproductive disorders, developmental destruction and neurological impairment.

The Dioxin War is the story of the people who fought to reveal the truth about dioxin. Huge multinationals Dow and Monsanto both manufactured Agent Orange. Robert Allen reveals the attempts by the chemical industry, in collusion with regulatory and health authorities, to cover up the true impact of dioxin on human health. He tells the remarkable story of how a small, dedicated group of people managed to bring the truth about dioxin into the public domain and into the courts - and win.
