The article analyzes changes in atmospheric pollution levels in Kazakhstan's largest industrial cities based on data from state environmental monitoring over the past several years. It examines the concentrations of major pollutants, including sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and PM2.5 and PM10 particulate matter. The use of a comprehensive approach combining the results of stationary observations, statistical data processing, and spatiotemporal analysis made it possible to identify trends in air quality and determine the most problematic regions with increased environmental stress. The results obtained make it possible to assess the effectiveness of the environmental protection measures being implemented and form the basis for improving the system of monitoring and managing atmospheric air quality in Kazakhstan. The practical significance of the study lies in the possibility of using the identified patterns to forecast and plan environmental policy at the regional level.
