Analysis of the impact of economic activity on atmospheric air quality in Ulan-Ude

[摘要] The growth of negative environmental impact requires increased attention to the processes of air protection. In recent years, significant imbalance of the biosphere has been clearly observed. This study proved a significant excess of negative environmental impact of Ulan-Ude in comparison with assimilation potential of the environment. Ulan-Ude, which is annually included in the list of the most polluted cities in Russia in terms of the level of atmospheric pollution, this problem is mainly due to the processes associated with the generation of electricity and motor transport. Very high concentrations of benzo[a]pyrene (hazard class 1), formaldehyde (hazard class 1) and particulate matter in Ulan-Ude contribute to an increase in the incidence of children and adults. High depreciation of environmental protection equipment, insufficient expenditures on atmospheric protection measures, and comparability of payments for normative and excessive pollution determine the inefficiency of the existing environmental policy.
