Persistent organic pollutants (POPs) encompass an array of anthropogenic organic and elemental substances and their degradation and metabolic by-products that have been found in the tissues of exposed animals.
As a consequence of bioaccumulation by, bio magnification of legacy and emerging, POPs are found in biota and humans. The potential biological effects of these contaminants on exposed plants, wildlife and fish and the people who harvest them are extremely important.
Highly dissolved in fat -this enables CDDs and CDFs to bio-accumulate in fatty tissues of living organisms, which results in higher levels in an individual than levels in the environment or in food The most vulnerable are the young who are exposed in-utero and post-partum (breast feeding) Although human exposure from food can be small, organochlorines do not break down easily and can build up in the body over time Affect human health at very low levels in terms of:
