Abstract
The purpose of the workshop was to examine the existing toxicity and exposure database on polychlorinated biphenyls (PCBs) to ascertain the feasibility of developing toxicity equivalency factors (TEFs) for PCB congeners. Given the widespread acceptance and acknowledged utility of the TEF method for assessing risks associated with exposures to complex mixtures of chlorinated dibenzo-p-dioxins and dibenzofurans, some experts have urged development of comparable TEF schemes for other structurally related chemicals, such as PCBs. Information from the workshop will contribute to Risk Assessment Forum recommendations on whether to pursue development of a TEF scheme for PCBs.
