Abstract. The atmosphere is the environment into which human, animal and plant waste is discharged. Industry and transport are the main sources of these emissions. The protection of atmospheric air begins with enterprises: with environmental monitoring at the enterprise and with the determination of the maximum permissible norms for the impact on the natural environment, which guarantee the ecological safety of the population. The purpose of this scientific work is to determine the level of atmospheric pollution by harmful substances contained in the emissions of the Novospassky cement plant JSC "Spasskcement". The methodological basis of the work is the author's assess-ment of
the impact of pollutant emissions on the air using measurement methods and comparative analysis. The main attention in the work is paid to the quantitative assessment of the impact of emissions of pollutants on the at-mospheric air from 112 sources located on the territory of the Novospassky cement plant JSC "Spasskcement". Emissions were assessed by hazard classes. The calculation of the dispersion of pollutants in the atmospheric air of the area where the enterprise is located was carried out, taking into account the background for 34 pollutants and 5 groups of summation for the winter and summer periods. A comparative analysis of the calculated air pollution with the assessment of
pollution by the FGBU "Primorskoe UGMS" has been carried out. The results of the study indi-cate that the predicted level of atmospheric pollution, obtained by calculation, is assessed as "low", which coincides with the assessment of the FSBI "Primorskoe UGMS".
The scientific novelty of the research lies in the application of the calculation method to confirm instrumental measurements.
