Polychlorinated biphenyls (PCBs) are harmful to the environment due to their persistence and bioaccumulation in ecosystems. They can accumulate in the tissues of living organisms, leading to toxic effects on wildlife, including reproductive and developmental issues. PCBs contaminate soil and water, affecting food chains and posing risks to human health through consumption of contaminated fish and animals. Their chemical stability makes them resistant to degradation, prolonging their environmental impact.
