Persistent Organic Pollutants (POPs) are toxic chemicals that remain in the environment for long periods. They can travel long distances through air and water, accumulating in the food chain and posing risks to human health and wildlife. Common examples of POPs include DDT, PCBs, and dioxins. These substances are resistant to degradation, meaning they do not break down easily in nature. As a result, they can persist in soil, water, and living organisms for years. Efforts to manage and reduce POPs are essential for protecting ecosystems and public health, leading to international agreements like the Stockholm Convention.
