Abstract:

With the aid of environmental models, transfer, fate, bioaccumulation and biomagnification of contaminants in a multi-compartment environment was simulated, which is not only a basis for evaluating ecological and health risks of persistent organic pollutants (POPs) in food chain, but also an important approach to and means of studying environmental processes of the pollutants. It is of great significance to use bio-accumulation models in studying bioaccumulation and biomagnification of POPs in food chain to the evaluation of ecological and health risks of the POPs. A review is presented with emphasis on various bioaccumulation models available at home and abroad to simulate POPs bioaccumulation and biomagnification in the terrestrial food-chain, including principles, features, merits and shortcomings of the models and some case studies of their applications. Moreover, modifications of the models were recommended. Obviously the lack of basic environment parameters, shortage of experimental data, and plant species peculiarities are the major causes hindering development of this kind of models.

Key words: POPs, terrestrial food-chain, bioaccumulation models
