PCB contamination

PCB contamination refers to the presence of polychlorinated biphenyls (PCBs) in the environment, typically resulting from improper disposal or leaks from industrial products. PCBs are harmful chemicals that were once widely used in electrical equipment and other applications due to their stability and resistance to fire. However, they are toxic and can accumulate in living organisms, leading to health risks such as cancer and hormonal disruption. Contaminated soil, water, or air can pose significant threats to wildlife and human health, prompting efforts to clean up and regulate PCB use to safeguard ecosystems and communities.
