Use of traditional foods in a healthy diet in Alaska: Risks in perspective. Second Edition: Volume 1. Polychlorinated biphenyls (PCBs) and related compounds
Polychlorinated biphenyls (PCBs), dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and polybrominated diphenyl ethers (PBDEs) are lipophilic, persistent, usually man-made chemicals. Due to concerns over potential adverse ecological and human health effects, the manufacture of PCBs was banned several decades ago by many industrial nations. However, trace amounts of PCDDs and PCDFs continue to be unintentionally produced during some industrial processes.
