Most polluted cities in Tuscany, Italy

No city in Tuscany, Italy has enough readings to rank so far this year.

25 monitors in Italy haven't reported for more than two days. Cities that rely on them are missing from the 24-hour board and may drop from the longer ones; that isn't clean air, and they return when the data does.

A city joins this ranking with enough days of readings so far this year; none here has that right now, so there is nothing to map or chart.

Estimated: cities without a monitor

Tuscany cities we can't measure, with model estimates for the last 7 days. Listed by population, not ranked: estimates aren't precise enough to rank. Model estimates from the Copernicus Atmosphere Monitoring Service (CAMS), adjusted to measured cities nearby where there are any. Adjusted, a single day lands within ×1.5 of what a monitor would read about two times in three; unadjusted, it can be off by half or double. Treat them as a guide, not a measurement.
