The research aimed to study the oxygen production and the dynamics of the leaf blade dust-collecting ability of hawthorns growing in contrasting ecological and climatic areas. Hawthorns in urban green spaces are a fairly common tree species and play an important hygienic role in purifying the atmospheric air from dust and harmful impurities and have sufficient oxygen productivity. Hawthorn trunks ensure 70% of all oxygen productivity and gas absorption. Meteorological conditions of the ecological regions under study have a huge impact on the amount of dust adsorbed on the tree surface. The dust-holding capacity of hawthorns, which, according to research, have rough lamina, increases towards the end of the growing season. The maximum dust deposition is observed in July, with the least amount of precipitation. Hawthorns that grow along highways experience the greatest environmental pressure. The difference is on average 1.8-1.9 times in comparison with the reference area. The maximum dust accumulation was found within the near-highway plantations characterized by an average density and vertical structure, as well as ventilation capacity. Two regions selected for research represent the technogenic environment of a large city. Therefore, to improve the quality of life and contribute to the improvement of the environmental situation, it is necessary to plant sustainable trees and shrubs within the city boundaries, which serve as a protective barrier to the deteriorating environmental situation.
