The data showed that nine of the 12 listed cities recorded AQI levels of 350 or above, indicating a significant deterioration in air quality across parts of northern India.
The concentration of highly polluted cities across Haryana, Uttar Pradesh, Punjab, Rajasthan and Delhi highlights the growing air-quality problem in northern India. According to an official, several cities across north India reported a spike in air pollution following , with air quality deteriorating amid increased emissions from firecrackers and other pollution sources. The rise in pollution levels has renewed concerns over the region’s air quality and the need for stricter enforcement of pollution-control measures.
Meanwhile, Delhi recorded one of its most polluted Diwalis, with the average AQI touching 376 on 8 November.
On Monday, several localities in Delhi recorded AQI levels above 350, indicating very poor to severe air quality. Areas with high pollution levels included Delhi Technical University (409), Narela (399), Chandni Chowk (394), Bawana (392), Burari crossing (390) and Lodhi Road (384).
Under CPCB’s classification, an AQI between 0 and 50 falls is considered ‘good’, indicating minimal health impact. A reading between 51 and 100 is classified as ‘satisfactory’, while an AQI of 101-200 falls under the ‘moderate’ category. An AQI between 201 and 300 is categorised as ‘poor’, and may cause breathing discomfort to people with prolonged exposure, particularly those with respiratory conditions. The ‘very poor’ cetegory covers AQI readings between 301 and 400 and is associated with respiratory illness on prolonged exposure, even among healthy people. The highest category, ‘severe’, applies to AQI levels between 401 and 500. At these pollution levels, even healthy people may experience cts, while those with existing health conditions may face more serious impacts.
Stage 3 of the Graded Response Action Plan (GRAP), an emergency framework designed to prevent air quality from deteriorating once pollution crosses specific thresholds, is currently active across Delhi-NCR, alongside special vehicle and dust-control rules that took effect on 1 November.
Imposed on 6 November, GRAP Stage 3 bans BS-III petrol and BS-IV diesel (or older) four-wheelers from plying in Delhi and the NCR districts of Gurugram, Faridabad, Sonipat, Ghaziabad, and Gautam Buddha Nagar.
