Abstract
The first results of studies of the elemental composition of atmospheric aerosol and soils of Northern Tajikistan by the method of inductively coupled plasma mass spectrometry (ICP-MS) made it possible to identify high values of substances in some samples. A brief overview of the main directions and results of the study of the content of substances in the composition of aerosol particles and soils in the territory of Northern Tajikistan for the period 2020-2022 is given. Enrichment factors for heavy metals and arsenic in aerosol particles are calculated. The main source of aerosol pollution in the Northern Tajikistan are emissions from the construction industry, motor vehicles, and human economic activity. Heavy metals and arsenic contained in man-made particles are transported by air currents over longer distances.
