What are PCBs?
Polychlorinated biphenyls, commonly known as PCBs, are industrial chemicals which were synthesized and manufactured in the United States beginning in 1929. They were used in many different types of products including hydraulic fluid, casting wax, pigments, carbonless copy paper, plasticizer, vacuum pumps, compressors and heat transfer systems. Because of their stability and resistance to thermal breakdown their primary use was as a dielectric fluid in electrical equipment. They are most commonly found in transformers and capacitors. While never manufactured in Canada, PCBs were widely used in this country.
