Analysis of aerotechnogenic pollution of the Vinnytsia using phytoindication methods

Abstract

Today, the anthropogenic impact on the environment is increasing, especially in urbanized areas and territories where active hostilities are taking place. Among a number of urgent environmental problems, it is possible to single out atmospheric air pollution, which occurs as a result of the concentration of road transport and industry in safe areas. The article presents the results of research into the state of atmospheric air pollution in the city of Vinnytsia using phytoindication methods, namely the degree of fluctuating asymmetry of warty birch leaves, and established the dependence of the fluctuating asymmetry on the level of traffic load. The research was conducted at the end of July in 2021 and 2022, after the end of the growing season of warty birch (Betula pendula). In the city of Vinnytsia, six representative experimental sites with different levels of anthropogenic load were identified. Fluctuation asymmetry coefficients of warty birch leaves were calculated for each experimental site and indicators of the asymmetry coefficient were determined. The level of motor vehicle load on experimental sites was established and a correlation-regression model of the dependence of the coefficient of fluctuation asymmetry of the leaves of the warty birch on the level of motor vehicle load was calculated. Conducting biomonitoring of aerotechnogenic pollution of urban ecosystems is necessary for finding ways to optimize its quality.
