Abstract

The influence of smoke from Siberian forest fires on the pollution of the surface layer of the atmosphere of Krasnoyarsk by PM_2,5 particulate matter is analyzed. The average daily maximum permissible concentration (35 μg/m³ ) was used as a pollution criterion. The pollution period was 12 days when calculating the average daily concentrations of PM_2,5 and 9.5 days when calculating the average hourly concentrations of PM_2,5. In the first case, the maximum concentration of PM_2,5 was 77.9 μg/m³ , and in the second case 164.5 μg/m³ . At a wind speed of about 6 m/s, the cleaning time for the city’s atmosphere was approximately 80 minutes.
