Most polluted cities, week of March 13, 2023
1,170 cities ranked by their average PM2.5 over the 7 days; the worst was Banja Luka, Bosnia and Herzegovina, at 33.6 µg/m³. A city needs measurements on 70% of the days to be ranked.
OpenAQ's archive, where our readings come from, has almost none for 6 of these 7 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; many cities elsewhere are missing from this board, not clean. Why.
