Abstract
Monitoring of acidic impurities in the atmosphere of urbanized areas and forecasting environmental risks for the population
Incoming article date: 29.09.2021Monitoring of atmospheric air in settlements allows you to control the environmental situation there and predict environmental risks for the population. It is known that acidic impurities in the atmospheric air of urban areas affect the human respiratory system. The proven relationship between acidic aerosols from the atmospheric air and the functioning of the human respiratory system indicates the relevance of studies of monitoring acidic impurities in the atmospheric air in order to predict environmental risks for the population. In this regard, the purpose of the study was to monitor the aerosol acidity indicator in the residential area of the Svetly Yar Republic (Svetloyarsk district of the Volgograd region) for the spring-summer period in 2019 and predict environmental risks for the population. The material for the study was aerosol particles from the leaves of apricot trees (Prunus armeniaca) from the village of Svetly Yar (Svetloyarsk district of the Volgograd region), from which aerosol suspensions were prepared and which were studied in terms of acidity (pH). The studies carried out made it possible to identify acidic impurities in aerosols in the village. Light Yar (pH = 4.56 + 0.028). This fact indicates the environmental risks for the population associated with the acidic environment of aerosols, since it is known that acidic air pollution can aggravate asthma, promote the development of bronchospasms, and inhibit the respiratory system. It is required to identify sources of pollution in order to develop environmental measures to protect the population from acidic impurities in the atmosphere.
