SPATIO-TEMPORAL VARIATION OF THE ELEMENTAL COMPOSITION OF ATMOSPHERIC AEROSOL IN TAJIKISTAN

The article presents the results of a study of the elemental composition of atmospheric aerosol in Dushanbe during dust invasions. The spatiotemporal distribution of chemical elements in atmospheric aerosol and soil in Tajikistan is also considered. Southern and Central Tajikistan is subject to dust invasions every year from April to November. In addition to this, enterprises in this region, such as a cement plant, thermal power plant and housing and communal services, constantly use coal as a raw material, so the increase in the content of chemical elements in the atmosphere is apparently associated with the chemical composition of burned coal, and it makes a certain contribution to atmospheric pollution.
