SmogRank / World / Slovakia / February 2023

Most polluted cities in Slovakia, February 2023

33 cities in Slovakia ranked by their average PM2.5 over the 28 days. Worst: Spišská Nová Ves at 35.2 µg/m³, #12 of 1,175 cities in the world. Cleanest: Poprad at 12.1. A city needs measurements on 70% of the days to be ranked.

OpenAQ's archive, where our readings come from, has almost none for 25 of these 28 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.
