Abstract
PM2.5 has grown to be a significant air quality concern in urban areas globally. Airborne particulate matter (PM) is a primary indicator of adverse health exposures, substantially contributes to disease burden, affecting both mortality and morbidity and acts as a climate-forcing agent, impacting visibility through the scattering and absorption of light in the atmosphere. In the field of PM2.5 sampling and source apportionment, there are still gaps and unsatisfactory in territorial and temporal coverage in Сentral Asia (CA). The rapid industrialization and industrial development of Kazakhstan have significantly increased urban air pollution indicators over the past few decades. One of the limitations of conducting such studies in Kazakhstan was the lack of measurements of PM in the fine fraction, short time series, and uneven data availability with the absence of pollutants at different types of measuring stations. At the moment, the capital сity of the country, Astana, has become one of the most polluted cities.
