Most polluted cities in Punjab, Pakistan, September 2025
7 cities in Punjab, Pakistan ranked by their average PM2.5 over the 30 days. Worst: Gujranwala at 67.9 µg/m³, #4 of 3,052 cities in the world. Cleanest: Bahawalpur at 35.3. A city needs measurements on 70% of the days to be ranked.
About 22.3M people in these 7 cities breathed unhealthy air on an average day of September 2025.
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.
