Abstract

Tashkent city is the capital of our country and a rapidly developing large city. Along with the growth of the city’s economy and population, the level of air pollution is also increasing. PM_2.5 and PM₁₀ particulate matter are indicators of air pollution. This article analyzes the level of pollution in Tashkent city from PM_2.5 and PM₁₀, examines its causes and negative effects. The dynamics of change was statistically analyzed based on the Mann-Kendal Test. According to the trend test results, significant changes were found for PM_2.5 in 2019 (Z=2.21), in 2020 (Z=2.11), in 2021 (Z=3.63), in 2022 (Z=2.31), and in 2023 (Z=3.21), with similar results for PM₁₀ (Z=2.02) and NO₂ (Z=2.26). Based on these results, necessary conclusions were drawn for future atmospheric air monitoring.
