- Learn about Polychlorinated Biphenyls | US EPA
What Are PCBs? Polychlorinated biphenyls, or PCBs, are a group of man-made organic chemicals consisting of carbon, hydrogen and chlorine atoms The number of chlorine atoms and their location in a PCB molecule determine many of its physical and chemical properties
- Polychlorinated biphenyl - Wikipedia
PCBs are derived from biphenyl, which has the formula C 12 H 10, sometimes written (C 6 H 5) 2 In PCBs, some of the hydrogen atoms in biphenyl are replaced by chlorine atoms There are 209 different chemical compounds in which one to ten chlorine atoms can replace hydrogen atoms
