Objectives. Purpose Monitoring of acidic impurities in the atmospheric air of residential areas of settlements is one of the areas of ensuring their environmental safety and is officially carried out at 221 stations in the Russian Federation in the study of atmospheric precipitation. Method. In areas where they are minimal, the author proposes an alternative method for assessing environmental pollution based on the preparation of aerosol suspensions. The purpose of this work was to study the acidity index (pH) of aerosol suspensions (washing off aerosols from the leaves of apricot trees (Prunus armeniaca) obtained in the Srednyaya Akhtuba region (Sredneakhtubinsky district of the Volgograd region) in the spring-summer of 2020. Result. The results of the research demonstrated acidic aerosols ( pH = 5.32 + 0.01) in the atmospheric air rp Srednyaya Akhtuba in comparison with the conditionally clean zone (SNT "Oroshenets", "Shelf"), (pH = 6.39 + 0.02) The data indicate environmental pollution and on environmental risks for the population. Conclusion. Acidic impurities in the atmosphere of the middle Akhtuba region in comparison with the conditionally clean zone (SNT "Oroshenets", "Shelf"), which indicates environmental risks for the population. sources of pollution in residential areas of the settlement of Srednyaya Akhtuba and to develop environmental measures to protect the population from acidic impurities contained in aerosols, which requires further study of the territory.
