1. POLICHLOROWANE BIFENYLE (PCB) POLYCHLORINATED BIPHENYL (PCBS)

2. A polychlorinated biphenyl is a synthetic organic chemical compound of chlorine attached to biphenyl, which is a molecule composed of two benzene rings. There are 209 configurations of organochlorides with 1 to 10 chlorine atoms. The chemical formula for a PCB is C12H10-xClx. 130 of the different PCB arrangements and orientations are used commercially and known as Aroclor. CHARACTERISTICS

3. PRODUCTION Production of synthetic compounds on a large scale started in the 19th century. Nowadays on a global market there are about 100 000 suppliers of compounds. Some of them are very long-lasting PCBs, which is treated as a benefit.

5. Due to PCBs' environmental toxicity and classification as a persistent organic pollutant, PCB production was banned by the United States Congress in 1979 and by the Stockholm Convention on Persistent Organic Pollutants in 2001. According to the U.S. Environmental Protection Agency (EPA), PCBs cause cancer in animals and are probable human carcinogens. PRODUCTION STANDARDS
