Most polluted cities in Gyeonggi-do, South Korea, May 2024
26 cities in Gyeonggi-do, South Korea ranked by their average PM2.5 over the 31 days. Worst: Yeoju at 22.0 µg/m³, #123 of 2,641 cities in the world. Cleanest: Gapyeong at 12.3. A city needs measurements on 70% of the days to be ranked.
About 87.8K people in these 20 cities breathed unhealthy air on an average day of May 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.
