Most polluted cities in Alberta, Canada, February 2024
14 cities in Alberta, Canada ranked by their average PM2.5 over the 29 days. Worst: Grande Prairie at 9.5 µg/m³, #728 of 2,437 cities in the world. Cleanest: Lethbridge at 5.0. 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.
Ranked by unhealthy days: the share of each city's measured days with a daily mean over 35.4 µg/m³ (US AQI 101+), Unhealthy for Sensitive Groups or worse on the US EPA's scale. Ties go to the higher average.
