This article examines the relationship between environmental pollution and health problems affecting human and non-human species. Specifically, it reviews existing evidence on Persistent Organic Pollutants (POPs) - a class of synthetic organo-chlorine chemicals and products introduced after World War II - and their adverse health effects on society and wildlife. Their fundamental characteristics, including toxicity, persistence, ability to migrate long distances, and bioaccumulation within the food chain, are presented. The reactions of international community, especially the U.N. Stockholm Convention on POPs recently signed by 122 countries, are discussed. The future needs of substitutes to harmful chemicals and mitigation of health problems already caused are discussed as well. The use of precautionary principles as a guide to public health and environmental policies is emphasized.
