Chemical Information

2,8-Dichlorodibenzo-p-dioxin

2,8-Dichlorodibenzo-p-dioxin is one of 75 chlorinated dibenzo-p-dioxin (CDD) congeners. CDDs are a class of manufactured chemicals that consist of dioxin skeletel structures with chlorine substituents. They are also persistent organic pollutants (POPs), thus their production is regulated in most areas. Dioxins occur as by-products from the manufacture of organochlorides, the bleaching of paper, chlorination by waste and drinking water treatment plants, municipal solid waste and industrial incinerators, and natural sources such as volcanoes and forest fires. (L177, L178)
