Prospects for Future Application of Fugacity Model to Fate Studying of POPs in China

POPs can stay long enough to diffuse and transfer sufficiently in the environment. Researches indicate that it‘s inadequate to study POPs‘ fate and environmental behavior, in order to get comprehensive knowledge of the POPs‘‘ fate and transfer processes in an area, experiment should be combined with model simulation. Recently multimedia models have become the primary choice in simulating organic pollutant‘‘s fate and assessing exposure risk to ecosystem for they can nearly represent the real environment. Among all models,with simple structure, less required parameters, fngacity model has been an efficient tool used widely on simulating the fate and transport of POPs and put into practice in many countries and areas successfully. On the basis of achievements in scientific research, this paper will emphatically take up the following three questions one by one that consist of fngacity model‘‘s principle, pivotal questions and application prospects in China,
