The International Agency for Research on Cancer (IARC) recently published its monograph on polychlorinated biphenyls (PCBs) and polybrominated biphenyls (PBBs). Based on their evaluation, the IARC Working Group classified PCBs as Group 1 (carcinogenic to humans). Dioxin-like PCBs were also placed into Group 1 have a peek at this website. PBBs were categorized as Group 2A compounds (probably carcinogenic to humans).
ToxStrategies scientists have extensive experience working with PCBs. Our work has included evaluating the human health and ecological effects of PCBs, conducting risk assessments on sites associated with PCB contamination, as well as evaluating and deriving safe levels of exposures for PCB compounds.
