| polychlorinated biphenyls |
A group of toxic, carcinogenic organic compounds containing more than one chlorine atom. PCB's were used in the manufacture of plastics and as insulating fluids in electrical transformers and capacitors. They behave much like DDT in the environment in that they are very stable compounds and are also fat-soluble; therefore, they accumulate in ever-higher concentrations as they move up the food chain. The use of PCB's was banned in the United States in 1979.

PCBs are chemicals used primarily, as flame-retardants, as coolants in industrial processes and in electrical transformers. PCBs were widely used between 1950 and 1970 in the United States, and are still used in many other nations. They resemble the dioxins and furans in their structure and environmental properties. They accumulate in fat and are probable human carcinogens. PCBs mimic estrogen and interfere with thyroid hormone. ...
