dioxinAromatic 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. How to thank TFD for its existence?
