Environmental monitoring of metallic impurities in fine dust (PM2.5) of settlements
Objective. The aim of the study is to identify metallic impurities in fine dust (PM2.5) in the residential area of Srednyaya Akhtuba (Sredneakhtubinsky rayon, Volgogradskaya oblast) exposed to the anthropogenic factor (expanded clay production) in a comparative characteristic with a relatively clean...

| description | Objective. The aim of the study is to identify metallic impurities in fine dust (PM2.5) in the residential area of Srednyaya Akhtuba (Sredneakhtubinsky rayon, Volgogradskaya oblast) exposed to the anthropogenic factor (expanded clay production) in a comparative characteristic with a relatively clean zone (garden non-profit partnership (SNT)) by indicators the number of particles (NPM2.5, %) and their mass fraction (D (dPM2.5), %).Method. The selection of particles (PM2.5) from the leaves of apricot trees and the preparation of aerosol suspensions was carried out according to international methods. The identification of the number and mass fraction of particles was carried out on the basis of the optical method according to GOST R 56929-2016.Result. The obtained values for the studied parameters were checked by the Wilcoxon T-test and were found at a significance level of p <0.05. In the residential area of Srednyaya Akhtuba, 35 times the mass fraction (D (dPM2.5), % of particles (PM2.5) exceeded the conditionally clean zone) and a slight increase in the number of particles (2 times) were found.Conclusion. Based on the results obtained metal impurities in fine dust (PM2.5) in the residential area of Srednyaya Akhtuba and environmental risks for the population living there are predicted. It is necessary to improve the system of protection of the urban economy at the enterprises for the production of expanded clay, etc., located in the industrial zone of Srednyaya Akhtuba. |
