Polychlorinated Biphenyls (PCBs)

Polychlorinated biphenyls (PCBs) are a group of synthetic organic chemicals that are used in various industrial and commercial applications, known to be used with electrical equipment, coolants and lubricants. Polychlorinated biphenyls are persistent in the environment and can accumulate in the food chain and are a type or organic contaminant that can be found in water, especially in areas where they were heavily used or disposed of improperly. Polychlorinated biphenyls are toxic to human health and wellbeing and can cause a range of health effects, including cancer, immune system dysfunction, and developmental problems. The production and usage of polychlorinated biphenyls have been banned in many countries, but they are known to still be found in the environment and may contaminate water sources.
