PCB (Polychlorinated Biphenyls)

Polychlorinated Biphenyls (PCBs) are chemical compounds once used in various industrial applications, such as electrical transformers and coolants, due to their non-flammability and stability. They are composed of two interconnected benzene rings with chlorine atoms attached. Despite their usefulness, PCBs are now known to be environmentally persistent and potentially harmful to human health, as they can accumulate in the food chain and may cause cancer, immune, and neurological issues. Most countries have banned or regulated their production and use, emphasizing the importance of proper disposal and cleanup of PCB-contaminated materials.
