In the Republic of Buryatia, due to long winters, there is a high demand for heat energy. The production of electricity and water has the most significant impact on emissions of pollutants into the atmosphere in the region. In this article, we studied snow precipitation sampled during or immediately after the snowfall in four settlements of the Republic of Buryatia (Ulan-Ude, Kyakhta, Gusinoozersk, and Selenginsk), in order to analyze air pollution. Analysis methods included particle size analysis and chemical analysis. In four samples collected in the capital city and in towns, there is an increased proportion (more than 14.8%) of particles smaller than 1 µm. According to the results of chemical analysis of water extracts from snow samples, concentrations of several elements from the 1st, 2nd, and 3rd hazard classes exceeded the threshold values of the 24-hour concentration standard in all the analyzed samples.
