POP transformations in soil compartments

The concept of equilibrium distribution of organic chemicals between medium components is widely used for the mathematical description of their degradation and migration processes in soil and other environmental compartments. This is also useful 

POPs Concentrations in background soils (Vasilyeva and Shatalov, 2004) MPC or IAL (Bakker et al., 1998) 

The following physical-chemical properties and related partition coefficients affect the distribution of a persistent organic chemical in soil  

in according to the concept of equilibrium distribution, the relation of an organic pollutant concentration in the soil solid and liquid phase is constant at any moment (Vasilyeva and Shatalov, 2004). The example of such an approach application for assessing exposure pathways of POPs to living biota is shown in Box 1.
