title: Numerical evaluation of the PCBs transport over the Northern Hemisphere.
abstract: The numerical evaluation of selected PCB congener (28, 118, 153, 180) transport over the Northern Hemisphere is carried out for 1996 using MSCE-POP model. This model is a multicompartment three-dimensional one and includes various environmental media such as the atmosphere, soil, vegetation, seawater, and sea ice. The spatial resolution is 2.5 degrees x2.5 degrees for all media except marine one (1.25 degrees x1.25 degrees ). The main model output information is deposition fluxes, spatial distribution of concentrations in environmental media, pathways and source-receptor relationships. Calculation results are analysed for the whole hemisphere and the Arctic region. In particular, this gives an opportunity to estimate the contributions of individual emission source groups to the Arctic pollution. The reliability of the model assessment is analysed by comparison between calculated and observed data.
