Polychlorinated biphenyls (PCBs) are probable human carcinogens, classified as weight-of-evidence Group B2 under the EPA Guidelines for Carcinogen Risk Assessment. Evidence on potential carcinogenicity from animal studies is 'Sufficient', and the evidence from human studies is suggestive but 'Inadequate'. The potency factor (F) for PCBs, including each of the specific Aroclors, is estimated to be 50.47 (mg/kg/day)-1 based on data from a study using Aroclor 1260, placing it in potency group 2 according to the CAG's methodology for evaluating potential carcinogens. Combining the weight-of-evidence group and the potency group, PCBs, including each of the specific Aroclors, are assigned a 'MEDIUM' hazard ranking.
