Most polluted cities in Luxembourg, July 2023

1 city in Luxembourg ranked by their average PM2.5 over the 31 days. Worst: Luxembourg at 7.8 µg/m³, #731 of 1,157 cities in the world. A city needs measurements on 70% of the days to be ranked.

OpenAQ's archive, where our readings come from, has almost none for one of these days. Cities in the United States and Europe have it 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.
