Novokuznetsk and Kemerovo, major industrial centers in Kuzbass, participate in the "Clean Air" federal project. Since 2018 and 2023, respectively, they have been implementing Comprehensive Action Plans devised to decrease contaminating emissions and thus improve the quality of the air and the quality of life of the population. The Plans are part of the "Ecology" national project. This study aimed to hygienically assess the quality of atmospheric air as part of the implementation of the "Clean Air" federal project, which involves improving the air monitoring system in the industrial centers of Kuzbass. Hazard identification and assessment of exposure levels were performed using the methodology provided in MR (methodological recommendations) 2.1.6.0157-19. In Novokuznetsk, air pollutant emissions decreased by 18.1%, while in Kemerovo they increased by 12.4%. The atmospheric pollution index was rated as "extremely high" and "high", respectively. As part of the study, we evaluated the spatial relationship between stationary and route air quality monitoring stations, identified emission impact zones for major industrial complexes, assessed the rationality of observation point locations, and implemented the necessary adjustments. Improving air quality monitoring will make it possible to obtain adequate and timely information on air quality and develop measures to improve the living environment and public health.
