Distribution of minor gas pollutants in the atmosphere over Lake Baikal

An analysis is made of the data obtained by means of the gas analyzer in comparison with meteorological conditions. The values of sulfur and nitrogen dioxide concentrations in the layer above water of Lake Baikal varied from 1 to 10 micrograms. The largest values of SO2 concentration were observed in the area of the Baikalsk Pulp and Paper Mill (Southern Baikal) under the plume. The calculated and measured values of sulfur dioxide and nitrogen oxide concentrations were compared to provide a good qualitative agreement.
