A study of the small-dispersed dust chemical composition on the leaves of apricot trees (Prunus armeniaca) in the residential area of the Sredneakhtubinsky district of the Volgograd region was coducted. The aim of the study was to assess the environmental situation in low-rise buildings near functioning constructional and machinery enterprises. The leaves of apricot trees (Prunus armeniaca) , growing in the residential area, were used as passive biomonitors. Chemical analysis of dust particles was carried out with the usage of a scanning electron microscope Versa 3D Dual Beam. As a result of the studies, the chemical composition of small-dispersed dust (PM1, PM2,5, PM10) on the leaves of apricot trees (Prunus armeniaca) , which consisted of C,O, Mg, Al, Si, Cl, K, Ca, F, P, S, Fe, Mo. Chemical elements such as: F, P, S, Fe, Mo are not specific for leaf blades of apricot trees (Prunus armeniaca) and are environmental pollutants that have fallen on the leaves of apricot trees (Prunus armeniaca) from atmospheric air. In the future, it is necessary to find out the sources of atmospheric air pollution in the residential area by non-specific chemical elements and their compounds for this type of plant in the Sredneahtubinsky district of the Volgograd region, and to develop a set of environmental measures aimed to reduce pollutants emissions into the environment, and improving the quality of life of the population.
