Delhi followed closely with a PM2.5 level of 215 µg/m³ after a significant rise from October. Uttar Pradesh dominated the list overall, with six of the top ten polluted cities, while Haryana contributed three and Delhi one. According to the Centre for Research on Energy and Clean Air, the region experienced almost no ‘safe AQI day’.
