Comparative Analysis of Atmospheric Air Monitoring Systems Data

Abstract

Purpose. To analyze the international experience in determining the state of atmospheric air, to conduct a comparative analysis of integrated indicators of atmospheric air quality on the example of the city of Mariupol. Methods. Processing and analysis of atmospheric air monitoring data were performed by calculation, statistical and graphical methods. Results. The study of the air quality of the city of Mariupol is carried out at 2 posts of the Automated Environmental Monitoring System in the Donetsk region and 13 automatic monitoring posts (AMP) at the borders of sanitary protection zones (SPZ) of the city enterprises. As a result of data analysis, the average percentage of pollutants, sub-indices and air quality indices according to the standards of Ukraine, EEA, EPA in 2020 were calculated. The obtained results differ in quantitative values, but on the scale of air quality are similar. Using the data of the Automated Environmental Monitoring System of Donetsk region, the average monthly concentrations of pollutants were calculated according to the data of regional posts and automatic monitoring posts on the border of sanitary protection zones. To assess the quality of atmospheric air, a data set was used: suspended particles, ozone, nitrogen and sulfur dioxide, which are used to calculate global air quality indicators. There is a tendency to increase the change in the concentration of formaldehyde in the atmosphere of the city during 2017 - 2020. Conclusions. The average percentage of pollutants, sub-indices and indices of air quality in Mariupol according to the standards of Ukraine, EEA, EPA are calculated. The obtained results differ in quantitative values, but on the scale of air quality are similar.
