Delhi records worst Diwali-eve air quality in a decade, AQI expected to worsen
• Delhi experienced its most polluted Diwali eve in the past decade, with the Air Quality Index (AQI) recorded at 369 on Saturday, categorised as 'very poor'. The Central Pollution Control Board (CPCB) data shows a worsening trend in pre-Diwali air quality over the years, with the highest AQI of 404 recorded in
• Experts predict that the AQI may enter the 'severe' category (above 400) due to emissions from firecrackers, stubble burning, and adverse weather conditions such as calm winds. The Supreme Court has allowed the use of green crackers during limited hours on 7th and 8th November, but reports suggest widespread availability of conventional firecrackers in markets. Meteorological conditions, including north-northwesterly winds, are expected to transport smoke from stubble burning in Punjab and Haryana to Delhi, further exacerbating pollution levels.
Impact & Risks
The deteriorating air quality poses significant health risks to Delhi residents, particularly vulnerable groups such as children, the elderly, and those with pre-existing respiratory or cardiovascular conditions. The AQI is expected to worsen post-Diwali due to increased emissions from firecrackers and stubble burning. Several areas in Delhi, including IIT-Delhi, Punjabi Bagh, and Jahangirpuri, have already recorded 'severe' air quality levels, with AQI readings exceeding 400. Prolonged exposure to such pollution can lead to respiratory distress, eye irritation, and other health complications.
