Most polluted cities in Virginia, United States, March 2024
11 cities in Virginia, United States ranked by their average PM2.5 over the 31 days. Worst: Harrisonburg at 7.1 µg/m³, #934 of 1,643 cities in the world. Cleanest: Hopewell at 4.8. A city needs measurements on 70% of the days to be ranked.
OpenAQ's archive, where our readings come from, has almost none from the United States for March 20, 2024: cities in the United States have it from the EPA's own records of the same monitors. Why.
About 0 people in this city breathed unhealthy air on an average day of March 2024.
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.
