Simulation of POPs behavior in soil compartment

To make adequate environmental policies concerning a reduction of the emission of POPs, the risks resulting from the deposition of POPs should be estimated. For that purpose some models to assess the risks of POPs in terrestrial ecosystems have been created (Bakker et al., 1998). The most important step of the approaches is developing models for computation of POP concentrations in soil from the data of their load on the land surface (see section 1). Based on these results, the estimating environmental risk from POPs accumulation in the soil compartment was carried out (Vasilyeva and Shatalov, 2004). 

Priority POPs and Their Permissible Levels in Soil 

Current characteristic of POP levels in background soils are considerably different (Table 1). In some soils their concentrations exceed their permissible levels, which also deviate substantially depending on country and land use.
