dioxin

Aromatic compound, any of a group of contaminants produced in making herbicides (e.g., Agent Orange), disinfectants, and other agents. Their basic chemical structure consists of two benzene rings connected by a pair of oxygen atoms; when substituents on the rings are chlorine atoms, the molecules are particularly toxic. The best-known, usually called simply dioxin, is 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD). It is extremely stable chemically; it does not dissolve in water but dissolves in oils (and thus accumulates in body fat). The extent of its human toxicity is disputed and the subject of continuing research.


dioxin [dī′äk·sən]
(organic chemistry)
A member of a family of highly toxic chlorinated aromatic hydrocarbons; found in a number of chemical products as lipophilic contaminants. Also known as polychlorinated dibenzo-para-dioxin.

Exposure to polychlorinated biphenyls (PCBs) or 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is known to increase atherogenic serum lipid levels in both animals and humans (Bombick et al.
At the time it was sprayed, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) was an unintended contaminant from the production of 2,4,5-T, and was present in Agent Orange and other formulations sprayed in Vietnam.
The present study investigated the effects of the dioxin, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on steroid-dependent development of amphibian gonaducts.
