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.

In the December 2003 report, titled Dioxins and Dioxin-Like Compounds in the Food Supply: Strategies to Decrease Exposure, the IOM lays out a public strategy to reduce dioxine exposure, chiefly through programs designed to reduce saturated fat intake among the population. |
