Purpose of the work. The purpose of this study is a comprehensive analysis of the dynamics of aerosol air pollution in a metropolis, taking into account the spatiaal characteristics of PM2.5 and PM10 concentrations, relationships with weather conditions, and the impact on the condition of urban green spaces.
Methodology. The methodology combined field, laboratory, statistical and geoinformation approaches. Data sources included SaveEcoBot (seven automatic stations), Sentinel‑2 satellite imagery, QGIS vector layers, real‑time information on missile strikes, dust storms and fires, as well leaf samples from Acer platanoides, Acer negundo, Tilia cordata, Populus nigra and Robinia pseudoacacia trees collected at the observation sites.
Scientific novelty. The study is a comprehensive analysis of the dynamics and spatial distribution of PM2.5 and PM10 concentrations in Kyiv in 2024, taking into account factors of military influence, dust storms and fires. For the first time, data from automated monitoring, satellite observations, and geoinformation analysis were combined. New empirical data were obtained on the level of damage of leaves under aerosol loading conditions.
Conclusions. The level of aerosol air pollution in Kyiv in 2024 demonstrated numerous short-term exceedances of the maximum permissible concentrations (MPC), caused by military shelling, dust storms and fires. Observations of urban plantations at the monitoring station sites revealed signs of stress in tree species, including chlorosis, necrosis, and pathogen-induced leaf damage. A relationship was found between the level of pollution and the morpho-physiological state of trees. The results emphasize the need for active monitoring of air quality, adaptive greening of the city and taking into account the impact of war in environmental policy. The applied approach is an effective tool for diagnosing urban ecosystems under conditions of multifactorial stress.
