Abstract
At present, the study of atmospheric air in urbanized areas is a highly topical issue in the Russian Federation and many worldwide countries. The article studies the existing system for monitoring the state of atmospheric air in Ulan-Ude. The analysis of air pollution in Ulan-Ude for the period 2010–2019 has been implemented. The role of autonomous heating sources, thermal power plants, and vehicles as air pollution sources in the city has been determined. The dynamics of changes in the primary pollutants are given: sulfur dioxide, carbon monoxide, nitrogen oxides, and other impurities. As a result of the study, the primary sources of pollutants were identified that affect the state of the atmospheric air in Ulan-Ude, characterized by a seasonal increase in the concentration of pollutants emitted into the surface layer of the atmosphere. The influence of vehicles on air pollution in Ulan-Ude is revealed. The authors proposed a systematic approach to the control of atmospheric air pollution for Ulan-Ude.
