Bioaccumulation and biomagnification of persistent organic pollutants (POPs) in food chain

The study on risk assessment and effective pollution control is ecologically important to understand the bioaccumulation and biomagnification of persistent organic pollutants (POPs) in both aquatic and terrestrial food chains. This paper reviews the characters of POPs, the mechanism, impact factors and models of bioaccumulation and biomagnification of POPs in the food chain. Many researchers in foreign countries studied the bioaccumulation and biomagnification of POPs in aquatic food chain. However, only a few researchers focused their studies on terrestrial food chain, and even fewer researchers did on the both food chains. However, there is little information on the bioaccumulation and biomagnification of POPs in food chain in China. Therefore, it is necessary to study the bioaccumulation and biomagnification, as well as the related treatment models of POPs in food chain when the POPs are now becoming more and more harmful to the environment and human health.
