Most polluted cities in Pakistan, April 2023

4 cities in Pakistan ranked by their average PM2.5 over the 30 days. Worst: Peshawar at 67.4 µg/m³, #4 of 1,316 cities in the world. Cleanest: Karachi at 22.7. A city needs measurements on 70% of the days to be ranked.

OpenAQ's archive, where our readings come from, has almost none for 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.
