    PCBs (polychlorinated biphenyls) are synthetic organic chemicals once widely used in industrial applications for their chemical stability, non-flammability, and excellent insulating properties. They are toxic because they persist in the environment, bioaccumulate in living organisms, and have been linked to adverse health effects such as cancer and endocrine disruption.
