Most people breathing unhealthy air in Tashkent Region, Uzbekistan, April 2023

1 city in Tashkent Region, Uzbekistan measured at 2 or more places, ranked by how many people breathed unhealthy air on an average day over the 30 days. The most people breathing unhealthy air: Salor, Uzbekistan, about 946 on an average day. A city needs measurements on 70% of the days to be ranked.

OpenAQ's archive, where our readings come from, has almost none for 3 of these 30 days. Cities in the United States and Europe have them from the EPA's and the European Environment Agency's own records of the same monitors; elsewhere a city's average is over its other days. Why.

About 946 people in this city breathed unhealthy air on an average day of April 2023.

Ranked by people: each city's population times its share of unhealthy days, those with a daily mean over 35.4 µg/m³ (US AQI 101+). That is how many people living there breathed unhealthy air on an average day. Only cities measured at 2 or more places at least 3 km apart are ranked: one monitor shouldn't speak for a whole city. Population is the city itself, not its wider metro area.
