The article evaluates the state of the city's air environment using bioindication. The purpose of the work is to determine the level of atmospheric air pollution on the territory of the Leninsky district of the city of Vladivostok. With the development of industry, energy and means of transport, anthropogenic pollution of the biosphere caused by human activity is continuously increasing. Emissions of industrial pollution, energy systems, vehicles into the atmosphere have a direct impact on all living things. The study of the consequences of anthropogenic impact on the environment, considered in the work, was carried out with the use of biological indication methods. For this purpose, living organisms were used as bioindicators reflecting the state of the environment. The optimal bioindicators in the city are birch leaves, since these are trees with high absorption abilities. During the formation of a leaf plate, as toxic substances accumulate, growth processes are inhibited and the leaf is deformed. The most accessible and widely used morphogenetic measure of developmental instability
is fluctuating asymmetry. Assessment of the atmospheric air quality of the Leninsky district of Vladivostok by the fluctuating asymmetry of the leaves of the fluffy birch (Vetula Pubescens Ehrn.), allowed us to determine the quality of the environment by studying the asymmetry of birch leaves. The
scientific significance of the work consists in assessing the suitability of using the biological indication technique in areas with specific natural and climatic characteristics that will affect the aeration regime of the territory. Practical significance of the work: as a result of the study of birch trees near
highways, data were obtained that indicate that the quality of the environment in the Leninsky district is assessed as "extremely unfavorable", which is the result of negative anthropogenic impact on the environment.
Keywords: atmosphere, air, emissions, Vladivostok city, air quality, asymmetry, leaves.
