toxicity equivalency factor (in risk assessment) (TEF)
Ratio of the toxicity of a chemical to that of another structurally related chemical (or index compound) chosen as a reference. Factor used to estimate the toxicity of a complex mixture, commonly a mixture of chlorinated dibenzo-p-dioxins (oxanthrenes), furans, and biphenyls: in this case, TEF is based on relative toxicity to 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-tetrachlorooxanthrene) for which the f = 1.
