The POPCYCLING-Baltic Model. A non-steady state multicompartment mass balance model of the fate of persistent organic pollutants in the Baltic Sea environment.

The POPCYCLING-Baltic model, typical multi-media mass balance model, divides the environment in 85 boxes or compartments, which are considered well-mixed and homogeneous, both with respect to the environmental characteristics and chemical contamination. These environmental phases are then linked by a variety of intercompartmental transfer processes.
