PollutionTracker Fact Sheet Dioxins and Furans

Polychlorinated dibenzo-p-dioxins (PCDDs or dioxins) and polychorinated dibenzofurans (PCDFs or furans) are produced unintentionally as by-products of industrial processes such as the combustion of waste products and the manufacture of pesticides and other chlorinated substances. They are also emitted from vehicles, the burning of salt-laden wood in coastal pulp and paper boilers, and in wood treatment.
