Presented are the results of investigations made as part of the R&D program «Investigation of the negative impact of emissions and discharges of harmful (polluting) substances on the Baikal natural territory, and working-out of scientifically groun­ded recommendations for their regulation». An assessment is made of changes in the amount of emissions from the organized stationary sources in the settlements of the Baikal natural territory. Motor transport emissions are calculated for settlements and along the federal Irkutsk — Ulan-Ude motor road. It is determined that the, in general, study territory does not show any substantial increase in pollutants emissions from stationary sources; motor transport emissions tend to increase because of an increase of the automobile fleet. Pollutions are assessed for the types of economic activity affecting the state of the atmospheric air of Baikal’s ecosystem. It is established that the largest contribution to pollutants emissions on the Baikal natural territory is made by the production and distribution of electric energy, gas and water as well as by transport and communication lines, manufacturing industries, and mining of minerals. We calculated the emissions from stove heating in settlements located in the central ecological zone of the Baikal natural territory. Mathematical models and snow survey data have been used in assessing the volumes of main pollutants depositing on the lake surface.

Keywords: atmospheric emissions, motor transport, deposition, pollution sources, Baikal natural territory.
