The article presents the results of an analysis of snow cover pollution in different parts of the Kirovsky district of Saratov. A comparison of the obtained data with the 1992 indicators was carried out. The connection between transport hubs with the highest dust load values and an increase in the number of cars was determined. Current spatial and temporal trends in snow cover pollution have been identified. The fact was confirmed that the highest concentration of dust in the snow cover is detected in areas with high traffic load. Determining the relationship between the increase in dust load in the study areas and the increase in the number of cars over a period of 30 years confirms the significant impact of transport on the ecological state of the environment in urbanized areas.
