Experimental studies of the industrial centers atmospheric pollution and modelling of its influence on the coast of Middle Baikal are summarized. Information on the mineral content of sulfur dioxide, sulfate, nitrogen oxides, nitrate in the atmosphere and atmospheric deposition (aerosol, precipitation, snow cover) is analyzed to determine the impact of regional sources on the composition of the atmosphere over the Middle Baikal. Quantity of sulfur oxides and nitrogen reaching to the Middle basin of Lake Baikal from big sources are estimated on the base of mathematical modeling

receptor modeling, identification of emission sources, monitoring snow cover, Delaunay triangulation
