Geoenvironmental studies of urban centers of the Baikal region are aimed at identifying the details of human impacts on the environment in this area in order to then find rational solutions to environmental problems of the region and improve the quality of life of its population. This article characterizes the environmental condition of the cities of Ulaanbaatar, Ulan-Ude, and Irkutsk and analyzes the relationship between socio-economic conditions and environmental problems of the territories. The data used in the study consists of statistical and archival materials, cartographic and literary works, and data from experimental observations. The urban centers of the Baikal region are characterized by different socio-economic conditions, but share some common features of modern agglomerations: an intense population concentration in capital cities, problems with utility lines, and increased environmental tension and discomfort. The analysis revealed a heavy environmental burden of the fuel and energy complex and motor transport. The environmental situation in the cities is also significantly influenced by factors, such as atmospheric circulation, the condition of natural waters, and the conditions for migration of chemical elements through the soil. An assessment of the level of human impact on components of the environment revealed extremely unfavorable conditions for self-purification of the atmosphere in Ulan-Ude and Ulaanbaatar, with the highest level of air pollution recorded in Ulaanbaatar. The highest level of soil pollution is observed in Irkutsk; it is due to large-scale industrial emissions and the fact that the soil of the territory has characteristics favorable for accumulation of pollutants. Ulaanbaatar is experiencing problems with the quality of water resources and the drinking water supply. Anthropogenic pressures on the environment of the cities create health risks for the population due to the entry of toxic pollutants into the air and into water bodies. [ABSTRACT FROM AUTHOR] |
