Advance in Spatially Explicit Environmental Multimedia Fate Models of POPs

Spatially explicit environmental multimedia fate models are used to give an accurate, detailed and distinct description of the transport, transformation and partition of POPs in multimedia. They are important tools in simulating the fate and assessing the risk of POPs. The spatial explicit multimedia models were divided into mass balance models and atmospheric transport models. Several currently available spatial explicit multimedia models such as GLOBO|POP, CliMoChem, BETR, IMPACT 2002, G|CIEMS, MSCE|POP and DEHM|POPs were compared based on the literature research. Development and the applications in domestic and abroad over the past decade of the models are reviewed, and the present situations in the development of this kind of models in China are analyzed. It is pointed out that the lack of measurable data and environmental parameters is a major factor restricting the development of the models. And the prospects of spatial explicit multimedia models are also proposed.
