Most polluted cities in Grand Est, France, 2024

No city in Grand Est, France had measurements on 70% of the days, so 2024 has no board for Grand Est, France.

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.

Grand Est has 10 cities ranked over the last 30 days, but none here: most of its monitors have no readings for 2024 in OpenAQ's archive, where ours come from, or too few to rank. Cities missing from this board weren't clean, just not measured.
