Atmospheric transport of heavy metals (Ni, Cu, Pb) over Siberia from two large industrial areas (Norilsk and Ural) is under consideration. The 5-day trajectories of air mass transport for each day of January, April, July, and October, 1981-2000, are analyzed. The model HYSPLIT 4 with reanalysis database NOAA (NCEP/NCAR Reanalysis Data Files) has been applied. The seasonal and long-term variations in average concentrations of anthropogenic heavy metals (from the above sources) in air and precipitations are estimated along with average fluxes of pollutants onto the surface for different regions of Siberia. The obtained results are in agreement with the published data measured at background regions. Long-range atmospheric transport contributes only a negligible portion of pollutants to the environment of the Baikal region as compared with local industrial sources.
