Abstract

The results on monitoring of chemical structure of atmospheric precipitation at Lake Baikal region are presented. The factors influencing on acidity and mineralization of wet deposition at different sites of the region (background, rural and urban) are considered. The special attention is given to dynamics of pH value, contents sulfates and nitrates. It is shown, that an acidity of precipitation is influenced not by absolute amount of strong acids anions, but by ratios of anions and cations in wet deposition. The fluxes of acidifying ions on an underlying surface of considered region are evaluated. With the help of mathematical simulation the possible contribution of regional anthropogeneous sources to acid loads (sulfuric and nitric acids) on water area of Southern Baikal with wet deposition is estimated.
