Tashkent air quality improves as good days increase from three to 14

The National Committee on Ecology and Climate Change in Uzbekistan reported that the average Air Quality Index in Tashkent improved during October.

The committee found that the monthly average Air Quality Index fell from 138 in October 2025 to 115 this year. The number of days with good air quality rose from three to 14, while the number of days with orange or red air quality levels decreased from 16 to four.

While the air remained cleaner for most of the month, quality declined between October 25 and 31. Experts linked the late-month pollution to falling temperatures, weak winds, and a lack of rainfall, which trapped pollutants near the ground. Laboratory analysis of 60 PM2.5 samples showed that industrial and transport fuel combustion caused 44.4% of particulate matter, while natural dust accounted for 42.6%.

Rainfall in the capital stayed nearly six times below the monthly average, which prevented dust from being washed out of the atmosphere.
