Abstract
Snow cover is an effective accumulator of dust fallout and provides objective information on the level of pollution. Pollution is among key factors that determine life quality in a city and is seriously considered when it comes to people’s residence preferences, house building policy, migration, and other aspects of urban environment management. Accurate pollution estimation and town zoning by pollution level based on these estimates are, therefore, challenges to be taken up in big cities with highly developed industries. This paper deals with the results of the 2018 study of the distribution of snow cover dust loading across Krasnoyarsk. Based on the norm, dust loading appeared to vary from low to high among the city districts. In winter 2018, dust loading dropped averagely 1.3 times as compared to the previous study. The northern and eastern industrial zones (Soviet and Lenin Districts, respectively) encompassing large industries were under the highest dust pollution. The dust pollution of snow cover was low in Krasnoyarsk in 2018.
