   2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and DLCs are structurally and toxicologically related halogenated aromatic hydrocarbons. The EPA recommends that the toxicity equivalence factor (TEF) methodology, a component mixture method, be used to evaluate human health risks posed by these mixtures, using TCDD as the index chemical.
