Polychlorinated Biphenyls
Polychlorinated Biphenyls (PCBs) are a group of man-made chemical compounds that were widely used from the 1920s until the late 1970s in products like electrical equipment, paints, and plastics due to their stability and resistance to heat. However, PCBs are environmentally persistent and can accumulate in the food chain, posing health risks to humans and wildlife, including cancer and immune issues. Although banned in many countries, PCBs still exist in older equipment and can be found in the environment, making their management and proper disposal important for health and safety.
