SmogRank / World / Kazakhstan / July 2023
Most polluted cities in Kazakhstan, July 2023
2 cities in Kazakhstan ranked by their average PM2.5 over the 31 days. Worst: Astana at 11.4 µg/m³, #401 of 1,157 cities in the world. Cleanest: Almaty at 10.7. A city needs measurements on 70% of the days to be ranked.
OpenAQ's archive, where our readings come from, has almost none for one of these days. Cities in the United States and Europe have it 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.
The US EPA's Air Quality Index for PM2.5 (2024 breakpoints). Show values as: µg/m³ · US AQI · India AQI · China AQI · European AQI · UK DAQI · Canada AQHI+. About the scales
