SmogRank / World / Slovakia / March 2023

Most polluted cities in Slovakia, March 2023

20 cities in Slovakia ranked by their average PM2.5 over the 31 days. Worst: Spišská Nová Ves at 20.2 µg/m³, #21 of 948 cities in the world. Cleanest: Poprad at 8.4. 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.
