Most polluted cities in Styria, Austria

10 measured cities, this year; 10 above the WHO annual guideline. Worst: Graz at 13.8 µg/m³, #622 in the world.

About 403 people in these 3 cities breathed unhealthy air on an average day so far this year.

Ranked by people: each city's population times its share of unhealthy days, those with a daily mean over 35.4 µg/m³ (US AQI 101+). That is how many people living there breathed unhealthy air on an average day. Only cities measured at 2 or more places at least 3 km apart are ranked: one monitor shouldn't speak for a whole city. Population is the city itself, not its wider metro area.
