Abstract:	The statistical characteristics of the weight concentrations of aerosols (particulate matter PM2.5 and PM10) in three points of Tbilisi city (A. Kazbegi av., A. Tsereteli av. and Varketili) from January 2017 to May 2020 are represented. The data of National Environmental Agency of Georgia about the mean monthly values of PM2.5 and PM10 are used. In particular, it is obtained that the greatest average values of PM2.5 during entire period of observations on the A. Tsereteli av. were observed (23.2 mcg/m³), smallest - on A. Kazbegi av. (16,8 mcg/m³). The greatest average values of PM10 during entire period of observations also on. A. Tsereteli av. were observed (50,5 mcg/m³), smallest - in Varketili (37,4mcg/m³). It is obtained, that the value of the linear correlation coefficient between the mean monthly values of PM2.5 and PM10 on all points changes from 0.52 to 0.95. The annual mean of PM2.5 and PM10 for all of measurements points are higher, that maximum permissible concentration according to the standards of the World Health Organization. The influence of limitation on the movement of truck transport in Georgia during April and May 2020 in connection with the pandemic of coronavirus COVID-19 to the decrease of the level of aerosol pollution of atmosphere is studied
