Toxicity Equivalent TEQ
Toxicity Equivalent TEQ :
Contribution of a specified component (or components) to the toxicity of a mixture of related substances. The amount-of-substance (or substance concentration) of total toxicity equivalent is the sum of that for the components B, C.....N: S n(TEQ) = n(TEQ)B + n(TEQ)C + ... n(TEQ)N Toxicity equivalent is most commonly used in relation to the reference toxicant 2,3,7,8-tetrachlorodibenzo-p-dioxin, 2,3,7,8-TCDD by means of the toxicity equivalency factor (TEF, f) which is 1 for the reference substance, hence: S n(TEQ) = fBnB + fCnC + ... fNnN
