Abstract

Eulerian three-dimensional model ASIMD (Asymmetric Improved Model) in version with 50- km spatial resolution was used for calculations of Pb and Cd depositions and concentrations for the period 1990-95. The main uncertainty of model results is related to emission data for which estimates of the ESQUAD project and TNO-emission prepared for UBA project were used. The TNO total emission is lower for Pb by 25% and for Cd - in 3 times. The comparison with measurement data provided by the PARCOM/ATMOS and EMEP network on mean annual wet deposition and concentrations in air and precipitations was made for the whole set (PARCOM/ATMOS+EMEP) and separately for PARCOM/ATMOS measurements supposing that the region of the North Sea is well conditioned by relatively
