Sunlight converts household anti-bacterial agent to dioxin

Sunlight can convert triclosan, a common disinfectant used in anti-bacterial soaps, into a form of dioxin, and this process may produce some of the dioxin found in the environment, according to research at the University of Minnesota. The researchers said that although the dioxin was a relatively benign form, treating wastewater with chlorine could possibly lead to the production of a much more toxic species of dioxin.
