dioxins (polychlorinated/brominated dibenzo- p -dioxins (PCDDs/PBDDs)), and furans (polychlorinated/brominated dibenzofurans (PCDFs/PBDFs)) are known for their distribution in the global environment, bioaccumulation and biomagnifications in the food chain, and toxic effects in wildlife and humans. ...
Different dioxin and furan compounds vary greatly in their demonstrated ability to cause adverse health effects in laboratory animals. The most toxic of the chlorinated dioxin and furan molecules in laboratory animals is 2,3,7,8-tetachlorodibenzo-p-dioxin (TCDD). Even among different species of ...

Dioxin exposure at significant dose levels has been linked to a large number of adverse health effects. Large acute exposures, resulting from chemical accidents or occupational exposure to dioxins, have caused a severe skin condition known aschloracne. A variety of other skin effects,...
Dioxins and furans were mostly below 20 ng total toxic equivalence per kilogram (TEQ kg−1), with the highest level of 113 ng TEQ kg−1 found in over 100 samples of different char types. The most toxic products were hydrochars produced from sewage sludge. Processing temperature and ...

The toxicity of dioxins is mediated through the aryl hydrocarbon receptor; a toxic equivalency factor (TEF) is used, assuming that the effects are additive and act via a common mechanism to cause toxicity (Boening, 1998, Kerkvliet, 2002). The TEF system was initiated for dioxins and furans ...
