Problem statement. Active human economic activity can significantly degrade the quality of the air environment. As a result of anthropogenic impact, numerous harmful impurities are released into the atmosphere, which negatively affect not only human health but also crop yields, soil conditions, aquatic ecosystems, etc. Geoinformation technologies can be an effective tool for assessing the volume and spatial distribution of emissions, as they integrate spatial and statistical data, create thematic maps, and interpret relevant indicators.
Analysis of the latest research and publications. This topic is widely covered in the scientific literature by domestic and foreign scholars who consider certain aspects of the problem, analyze specific situations and apply various assessment methods. The purpose of the research is to study, map, and analyze the density of pollutant and greenhouse gas emissions into the atmosphere by stationary sources within the territorial communities of Rivne district of Rivne region, with further identification of areas with the most pronounced environmental stress.
Material and methods of research. The research was based on official data for 2024 provided by the Main Department of Statistics in Rivne Oblast. The primary data set is presented in the form of a spreadsheet (Microsoft Excel file), which shows the total emissions (tons per year) and their distribution by type of pollutant and greenhouse gas by territorial community. The study combines methods of statistical processing, geographic information modeling, and spatial analysis.
Results. Using special ArcMap software, the authors developed thematic maps showing the distribution of pollutant and greenhouse gas emissions both in general and by individual groups (metals and their compounds, substances in the form of suspended solids, nitrogen compounds, sulfur dioxide and other sulfur compounds, carbon monoxide, carbon dioxide, non-methane volatile organic compounds). Cartograms were chosen as the main way to display information on maps. For each map, a color scale with appropriate gradations was used, which makes it easy to identify areas with the highest or lowest emission densities. All mapping materials were created using a single methodology. This ensures their consistency and allows for a correct comparison of relevant information between different territorial communities. The mapping modeling allowed us to identify potentially problematic areas with unfavorable environmental conditions and establish spatial patterns of their distribution. The air quality in the Horodok and Zdolbuniv communities, which are home to large-scale production of mineral fertilizers and cement, is of the greatest concern.
Scientific novelty and practical significance. Scientific novelty and practical significance. The geospatial analysis of pollutant and greenhouse gas emissions into the atmosphere by stationary sources within the territorial communities of Rivne district of Rivne region was performed on the basis of cartographic modeling. The results are of practical value for local governments, environmental services, and think tanks. They can serve as a basis for making informed management decisions, forming an effective regional environmental policy, and planning targeted measures aimed at reducing the technogenic load on the environment within the Rivne region.
