The work is devoted to the assessment of the atmospheric air on urbanized territories of Karaganda. This work determines the content of 11 pollutants. Measurements were carried out at 14 route posts with the maximum coverage of the entire city territory in June and January in order to obtain seasonal dynamics of atmospheric air pollution. As a result of measurements in July, the maximum single-time content of carbon monoxide, phenol, formaldehyde, hydrogen sulfide, and methyl mercaptans was recorded. In January, carbon monoxide predominates in the city’s air from pollutants, and increased concentrations of hydrogen sulfide are also observed in most parts of the city. Based on the results obtained, the atmospheric pollution index was calculated for 5 substances. Measurements of the pollutants were carried out at different times of the day. It was found, that contamination in almost all analyzed substances is higher in the daytime and in the evening. The main harmful impurities in the air of Karaganda are ozone, carbon monoxide, hydrogen sulfide, phenol, formaldehyde and methyl mercaptans. Ammonia was detected periodically. Based on the results the suggestions for improvement of the atmospheric air condition in the research territory were developed and adopted.
