It breaks down very slowly and still persists in the environment. Small particles stick to soil and remain in sediments in the bottoms of water bodies; it accumulates in plants, grasses, fish, marine animals, birds and animals.
A federal law called the Emergency Planning and Community Right to Know Act (EPCRA) requires facilities in certain industries, which manufacture, process, or use significant amounts of toxic chemicals, to report annually on their releases of these chemicals.
