Keywords: Krasnoyarsk forest-steppe snow cover mixed-grass pine forests man-made dust total fluorine pH of snowmelt water pollution zones of suburban area |
Summary: The article presents the results of six years of observations (2016–2022) of the accumulation of man-made dust in the snow cover. The studies were conducted in pine plantations of the Krasnoyarsk forest-steppe, along the main transport of industrial emissions in Krasnoyarsk. A comparison was made with pine forests growing in the background. Quantitative characteristics of the content of solid fluorides in the dust residue of snow waters are given. The results of comparing dust loads in the winter periods 2016–2022 with previously conducted long-term studies show that currently dust loads on pine forests have decreased by an average of 2 times. The contents of the total form of fluorine in solid sediment are insignificant in comparison with the clarke (percent abundance) of this element in the earth's crust. The acidity of snowmelt waters in the surveyed area ranges from 6.32 (slightly acidic) to 7.36 (slightly alkaline). The identified forms of snow cover pollution zones vary depending on the number of the South-westerly winds that carry industrial emissions from Krasnoyarsk to the studied massifs. Currently, the pine plantations under study grow in an area with moderate pollution. © Petrozavodsk State University |
