Most polluted cities in Gyeonggi-do, South Korea, July 2024

26 cities in Gyeonggi-do, South Korea ranked by their average PM2.5 over the 31 days. Worst: Yeoju at 14.2 µg/m³, #191 of 2,519 cities in the world. Cleanest: Anseong at 7.6. A city needs measurements on 70% of the days to be ranked.

About 153K people in these 20 cities breathed unhealthy air on an average day of July 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.
