Environmental impact

4.Persistent Organic Pollutants : Persistent organic pollutants (POPs) such as PCBs and dioxins are chemical compounds that resist biodegradation and therefore “persist” in the environment. As such, they tend to bioaccumulate up the food chain and can cause significant health concerns for both humans and the environment, associated with       increasing the risk of cancer, disrupting the endocrine system, and contributing to developmental and reproductive problems.
