Abstract
This study presents the research results of chemical composition of the snow cover in the Baikal region exposed to aerotechnogenic emissions from pollution sources located in the Irkutsk region and the Republic of Buryatia. The samples of snow cover taken along the Irkutsk–Listvyanka route, in the Selenga River delta and in the territory of the Baikal State Natural Biosphere Reserve were analyzed. The features of the spatial distribution of tracers from large industrial centers in the southern Irkutsk region and the Republic of Buryatia along the prevailing air mass transfers were studied. The percentage of unfavorable meteorological situations in which emissions from regional anthropogenic pollution sources could reach the coast of Lake Baikal was determined based on the calculations of spatial distribution of anthropogenic impurities from large cities being sources of pollution (HYSPLIT). The model of spatial distribution of anthropogenic substances from the large industrial centers of the Baikal region along the prevailing air mass transfers was shown.
