Air pollution in urban areas contributes to the development of various diseases among the population. In this connection, its environmental monitoring is relevant. Goals and objectives. The aim of the study was to study the redox potential of aerosols in the residential area of the village. Kuporosny (Volgograd, Sovetsky district) (experimental area) in comparison with the conditionally clean zone. The objectives of the study were to select aerosol particles in the leaves of apricot trees (Prunus armeniaca L.); preparation of aerosol suspensions from the leaves of apricot trees; study of the ORP of aerosol suspensions when they are infused for 5 minutes in distilled water; discussion of the obtained results. Methods. Leaves of apricot trees (Prunus armeniaca L.) in the amount of 10 pcs. placed in a glass dish, added 100 ml. distilled water, stirred them for several minutes with a glass rod to wash the particles from the surface of the leaves. As a result, aerosol suspensions were obtained, in which the ORP was studied. The ORP value was measured using electrochemical equipment (SevenCompact pH meter S220, manufacturer: Mettler-Toledo GmbH, Switzerland). Results. Established air pollution residential area in the village. Vitriol based on low values of the redox potential (Eh=30.03+0.27 (mV)) compared to the conditionally clean zone (Eh=140.83+0.81 (mV)). Conclusion. The results obtained indicate the predominance of recovery processes in the atmosphere of the residential zone of the village. Vitriol, the deterioration of its oxygen regime and the development of environmental risks for the population living there. In this connection, it is required to establish sources of pollution and develop appropriate environmental measures.
