Abstract

This study investigates the changes in concentrations of key air pollutants - carbon monoxide (CO) - in Tashkent city over a 30-year period from 1994 to 2023 in summer. The aim of the research is to analyze quantitative trends in these pollutants, generate spatial distribution maps, and identify the primary sources of air contamination. Data were collected from 12 observation stations operated by the Hydrometeorological Service of the Republic of Uzbekistan. Spatial analysis was conducted using GIS technologies, particularly the Inverse Distance Weighting (IDW) interpolation method in ArcGIS Pro. Seasonal maps were created at five-year intervals. Additionally, graphical analysis and descriptive statistical methods were used to assess the trends in pollutant concentrations. Results indicate that concentrations of CO peaked between 1994 and 2003, followed by a significant decline starting in 2008. This research provides a scientific foundation for air quality monitoring and environmental safety initiatives in Tashkent city.
