In particular, on the evening of September 29, the concentration of fine particles RM2.5 in Tashkent amounted to 166 micrograms/m3, and Tashkent was marked the second most polluted city in the world in the international IQAir database.

Dust pollution in our republic is associated with natural (dry climate, sandy loam, and loamy soils) and anthropogenic (transport, industrial, construction waste) factors. Also, conditions for natural air pollution are created by such causes as weak winds, temperature inversion, and stagnation of atmospheric air.

In addition, low ventilation of the atmospheric layers in cities, a large amount of urban traffic, congestion, large-scale construction, a lack of green spaces - all these meteorological conditions and anthropogenic loads lead to high air pollution.

For information: there are more than 638.8 thousand cars in the city of Tashkent. In addition, on average, 150 to 300 thousand cars enter the capital in one day. In Tashkent, the number of emissions of pollutants into the atmosphere from motor vehicles in 2021 amounted to 212.4 thousand tons, and in 2022, it was 403 thousand tons, with an increase in harmful emissions of 190.6 thousand tons (47.3%).
