Polychlorinated Biphenyls (PCBs) are still being produced and we are still coming in direct contact with them. They pose a real threat to human health and the environment.
What are PCBs?
PCBs are a group of manmade chemicals that have been manufactured since 1929 because they don't burn easily and are good insulating materials and plasticizers. They were banned from manufacture and use in the United States in 1979 due to health risks, however, they are still found in everyday products due to Congress allowing exceptions such as being produced as an inadvertent contaminant in things like caulk, paint, dyes, and pigments.
Where are PCBs found?
PCBs are currently allowed to be used in hundreds of industrial and commercial applications. The regulations allowing use and distribution are discussed at NTTC's Potential PCB Regulatory Revisions page.
