Dioxin

Dioxins are highly toxic, persistent, and bioaccumulative compounds found in the environment. They occur naturally at trace levels, but are also a byproduct of a number of industrial processes, including combustion (commercial, medical or municipal waste incineration), burning fuels, chlorine bleaching of pulp and paper, herbicide and pesticide manufacturing, chemical manufacturing, refining and processing, electrical power generation, and iron and steel production. Studies demonstrate that 90% of human dioxin exposure occurs through diet, from the consumption of fish, meat, or dairy products, and that the compound accumulates in food chains through atmospheric deposition. Dioxins can cause a number of adverse health effects to humans and animals, including impacts on reproduction and development; suppression of the immune system, endocrine system and nervous system; skin disorders, such as chloracne; liver damage; elevated incidence of diabetes; heart and kidney disease; and cancer.
