What are Dioxins?
Dioxins are a family of polychlorinated dibenzo-p-dioxin compounds that are found everywhere in the environment, generally at low levels. These large, complex molecules do not easily biodegrade and are extremely persistent. The most toxic and readily found is 2,3,7,8-tetrachlorodibenzo-p-dioxin commonly known as TCCD. In addition, there are certain dioxin-like substances, brominated and chlorinated dibenzofurans (CDFs), and certain polychlorinated biphenyl (PCBs) that appear to have similar toxic effects. There are 219 possible chlorinated dibenzodioxins (CDDs) and dibenzofurans.
