SmogRank / World / Italy / January 2023

Most polluted cities in Italy, January 2023

7 cities in Italy ranked by their average PM2.5 over the 31 days. Worst: Turin at 26.1 µg/m³, #48 of 993 cities in the world. Cleanest: La Spezia at 9.4. A city needs measurements on 70% of the days to be ranked.

OpenAQ's archive, where our readings come from, has almost none for 7 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; elsewhere a city's average is over its other days. Why.
