Abstract
The main physicochemical properties (content of chemical elements, mineralogical and granulometric composition) of suspended solids in the atmosphere of Yakutsk sampled in the summer of 2019 were determined on the territory of the city, a geochemical study of suspended solids (SS) in the surface atmosphere, soil and snow cover was carried out. SS entering the surface atmosphere are polydisperse and comprise a combination of solid particles of different sizes. About 70 % of the amount of SS in the atmosphere is related to dust itself, aerosuspensions account for 20 %, and medium-finely dispersed suspended particles accout for about 10%. Polydisperse SS contain toxic elements: Mn, Co, Cu, Cd, Pb, Zn. The most environmentally hazardous particles are medium-finely dispersed ones with a high content of elements of the 1st and 2nd classes of toxicity: Cd, Pb, and Cu. The average annual concentration of SS in the air of the city is 1.8 times higher than the sanitary standards. Suspended substances (dust and aerosols) adversely affect human health.
