Dioxin causes disease and reproductive problems across generations, study finds

Dioxin causes disease and reproductive problems across generations, study finds: Since the 1960s, when the defoliant Agent Orange was widely used in Vietnam, military, industry and environmental groups have debated the toxicity of its main ingredient, the chemical dioxin, and how it should be regulated. But even if all the dioxin were eliminated from the planet, researchers say its legacy will live on in the way it turns genes on and off in the descendants of people exposed over the past half century.
