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. How to thank TFD for its existence?

Source: Adapted from "Draft Exposure and Human Health
Reassessment of 2,3,7,8-Tetrachlorodibenzo-p-Dioxin (TCDD) and Related
Compounds," Volume 3, Chapter 3, Table 3-56, U. The most toxic and notorious member of the
family is 2,3,7,8-tetrachlorodibenzo-p-dioxin, or TCDD, widely known as
the contaminant in the Vietnam War herbicide Agent Orange. Exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is
associated with increased risk for cancer, diabetes, and reproductive
toxicities in numerous epidemiologic studies (Schecter and Gasiewicz
2003). |
