Abstract

Using the example of mercury and lead, we discuss the results of the calculations of the distribution and deposition of hazardous substances of the first hazard class in the atmosphere of the Angara and Baikal regions, which were obtained through a mathematical model. We indicate that the enterprises in Slyudyanka and Baikalsk mainly contribute to the pollution of Southern Baikal with mercury; their contribution is 72 %. The remaining mercury input comes from the Irkutsk-Cheremkhovo industrial complex. The enterprises in Slyudyanka and Baikalsk also mainly contribute to the pollution of Lake Baikal with lead (59-79 %). The contribution of the Irkutsk-Cheremkhovo industrial complex and the sources located in the valley of the Selenga River is much lower due to their remoteness.
