# The toxic equivalents of the 17 toxicologically significant PCDD and PCDF congeners are calculated using the following formula:
where TEFi is the WHO 2005 value of the toxicological equivalence factor for congener i of the 17 PCDD and PCDF congeners of toxicological significance listed below, Ci is the concentration of congener i in µg/kg (ppb) and the summation (TEQ, µg/kg) is performed over all 17 congeners.
The 17 toxicologically significant polychlorinated dibenzodioxin (PCDD) and polychlorinated dibenzofuran (PCDF) congeners:
