Abstract

From 1929 to 1978 polychlorinated biphenyls (PCBs) were widely used as dielectric fluids, hydraulic fluids, solvent extenders, and plasticizers. Several hundred million pounds of PCBs were released into the environment (Shiu and Mackay, 1986). It has been estimated that 50–80% of the PCBs in the environment have been deposited in the North Atlantic Ocean, and that the major continental sink for PCBs is freshwater sediment (NRC, 1979). PCBs tend to accumulate in biota and have been associated with potential health effects; consequently, their environmental fate is important.
