SmogRank / World / Romania / March 2023

Most polluted cities in Romania, March 2023

4 cities in Romania ranked by their average PM2.5 over the 31 days. Worst: Bucharest at 19.1 µg/m³, #32 of 948 cities in the world. Cleanest: Craiova at 14.7. A city needs measurements on 70% of the days to be ranked.

OpenAQ's archive, where our readings come from, has almost none for 20 of these 31 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.
