Abstract

In order to obtain a reliable assessment of the state of the urban environment, it is necessary to analyze the quality of atmospheric air in the process of monitoring. Currently, geoinformation analysis allows identifying spatial patterns of atmospheric air pollution. The purpose of the study is to analyze the level of chemical pollution of atmospheric air in the cities of Stavropol, Nevinnomyssk, Pyatigorsk using geoinformation technologies. Space images and vector data were used to prepare the map basis for residential and industrial settlements zones. A geodatabase was created to build geoinformation models of maximum concentration of substances and complex index of atmospheric pollution. The geodatabase includes attribute data on concentration of substances in the vector layer of “sampling points”. It has been processed in QGIS program, using the weighted distances method. For the integrated analysis, a map of the index dynamics was created and mapping work was carried out in order to assess the integrated air pollution index for each year under study. The article presents the analysis of priority contaminants for 2019–2021 in large and actively developing industrial centers of Stavropol Region, including Stavropol, Nevinnomyssk and Pyatigorsk. As a result of the study, it was established that between 2019 and 2021 the level of chemical pollution of atmospheric air in the cities of Stavropol, Nevinnomyssk, Pyatigorsk was assessed as low. At the same time, a steady trend towards an annual increase in the complex atmospheric pollution index was registered. In Stavropol, phenol and nitrogen dioxide make the major contribution to the chemical pollution of the city’s atmosphere. Increased concentrations of substances were noted in the industrial zone of the city as well as along main transportation routes. In Nevinnomyssk, the main contaminants are: carbon oxide, nitrogen oxide, nitrogen dioxide, ammonia and phenol. Phenol and nitrogen dioxide make the greatest contribution to the chemical pollution of the atmosphere of Pyatigorsk. The resulting geoinformation models allow clearly identifying the main areas of air pollution and providing a basis for calculating indicators of the quality of life in cities.
