Most polluted cities in Ilfov, Romania, 2023
1 city in Ilfov, Romania ranked by their average PM2.5 over the 365 days; 1 above the WHO annual guideline (5.0 µg/m³). The only one: Baloteşti at 12.0 µg/m³, #201 of 1,302 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 56 of these 365 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.
Ilfov has 8 cities ranked over the last 30 days, but only 1 here: most of its monitors have no readings for 2023 in OpenAQ's archive, where ours come from, or too few to rank. Cities missing from this board weren't clean, just not measured.
