The results of analysis of the spatio-temporal distribution of ecotoxicant concentrations in the atmosphere of Russian regions were obtained on the basis of satellite observations of nitrogen and sulfur dioxide, formaldehyde, carbon monoxide and aerosol concentrations in the period from 2004 to 2023. As a result of the study, subjects of the Russian Federation characterized by different values of pollutant concentrations were identified, and the regions were ranked in accordance with these indicators, taking into account the hazard classes of ecotoxicants. Using cluster analysis, territories with a similar structure of air pollution by various ecotoxicants were also identified. An assessment of trends in average annual concentrations of ecotoxicants made it possible to identify regions in which statistically significant changes in the concentrations of various pollutants in the lower troposphere are observed. The obtained data can be useful for analyzing the environmental situation in large areas and developing proposals for its improvement in specific regions, taking into account the identification of the most negative factors that determine the place of the region in the overall rating.
Keywords: concentrations of ecotoxicants, nitrogen dioxide, sulfur dioxide, formaldehyde, carbon monoxide, aerosol, ranking of subjects of the Russian Federation, zoning of the territory
