Abstract
The content of particulate matter PM2.5 and PM10 in the surface air layer of the city of Tyumen in June 2020 is estimated. The measurements were made using a hand-held portable particle counter AIR TESTER CW-HAT 200. The content of PM2.5 and PM10 in the city air is not highly variable; their average values are several times less than the one-time maximum permissible concentrations. This allows us to conclude that the surface air in Tyumen is moderately polluted with suspended particles. With the help of ArcGIS 10.6.1 software, schemes of the distribution of particles over the city territory are constructed; two highly polluted regions are identified caused by high traffic and wind pattern, respectively. The correlations between the content and distribution of PM2.5 and PM10 with air temperature and relative humidity are analyzed.
