Pollutants and Carcinogens in the Atmosphere of Voronezh

Abstract

The purpose of the study is to provide a spatial and temporal analysis of the results of atmospheric air monitoring in the city of Voronezh. Materials and methods. The article presents the results of analysis of daily monitoring data of "Voronezh Regional Center for Hydrometeorology and Environmental Monitoring" for the content of pollutants in the atmospheric air of Voronezh at 5 stationary observation stations operating in accordance with Guidance Document 52.04.186-89 for the period from 2015 to 2019. The research methodology is based on a cartographic analysis of the distribution of the main pollutants and their comparison with the criterion values defined in the governing documents. Assessment of air pollution features was carried out using a comprehensive atmospheric pollution index (API) recommended by the requirements of hygienic standards HS 2.1.6.3492-17. Results and discussion. The result of the study was to establish the features of spatial and temporal distribution of pollution fields by various pollutants, as well as studied their dependence on the seasons of the year. Mapping of the pollutants under study on the territory of Voronezh was carried out and their seasonal dynamics was established. Conclusion. In the spatial distribution of the main pollutants on the territory of Voronezh there is a stable localization of pollution foci, due to the functional structure of the city. For some pollutants a strong dependence of concentration on the season of the year is expressed, which indicates the dependence of the concentration of pollutants on weather conditions and, above all, on the thermal regime.
