Aerotoxicants — air pollutants (aerosols, nitrogen and sulfur dioxides, formaldehyde and carbon monoxide) have a significant impact on the health of people and ecosystems. Analysis of ecotoxicant content is important for understanding processes in the surface layer of the atmosphere and monitoring air quality. In recent decades, a system of remote methods for obtaining information on atmospheric pollution has been developed, based on Earth remote sensing devices. Based on satellite observations, the study analyzed long-term data on the content of aerotoxicants, as well as water vapor and the intensity of solar radiation in the atmosphere of 89 subjects of the Russian Federation. Statistical processing of the data was carried out. Trends in the concentrations of aerotoxicants were calculated and their statistical significance was determined. As a result of image processing, maps of average long-term values and standard deviations of aerotoxicant concentrations, as well as maps of concentration trends for all regions of Russia and adjacent territories, were compiled. Data analysis showed a clear connection between high concentrations of nitrogen and sulfur dioxides and urban and industrial agglomerations. High concentrations of aerosol and carbon monoxide are most likely related to emissions from forest fires. For most regions, an increase in nitrogen dioxide and sulfur dioxide, aerosol and solar radiation was noted, although in regions with high concentrations of nitrogen dioxide such as Moscow, Saint Petersburg, Moscow and Leningrad regions, a decrease in concentrations was observed. Decreases in average annual values of formaldehyde, carbon monoxide, and water vapor were observed for most regions. Satellite imaging capabilities for determining airborne toxicant concentrations are continually improving, and the availability of materials is growing. All this makes satellite observations, in combination with ground measurements, a useful tool for analyzing the environmental situation over large areas.
