Abstract
The concentrations of heavy metals (or metal oxides) and arsenic in samples of atmospheric aerosol and soil collected in northern Tajikistan in 2011 to 2019 are determined. Their local sources, mainly anthropogenic (automobile transport, metallurgical enterprises, open tailing dumps, etc.) are discussed. Possible sources of air transport of pollutants to the territory of the Sogd region are identified on the basis of the HYSPLIT back trajectory model
