Abstract
A comparative assessment of the concentrations of PM2.5 in the surface atmosphere over the territory of the city and over the water area of the Yenisei River was carried out. It is shown for time periods from several days to two years that, with rare exceptions, pollution over the river is lower than over the territory of the city. This pattern persists during periods of unfavorable meteorological conditions and during pollution of the urban atmosphere by the smoke of forest fires.
