On November 12, IIT Delhi recorded an AQI of 414, pushing the capital's overall air quality index beyond 321, the highest levels this winter.
IIT Delhi's air‑quality monitoring station logged an Air Quality Index (AQI) of 414 on November 12, driving the city's overall AQI past the 321 mark. The reading represents the highest pollution level recorded in Delhi this winter season.
The surge places the capital in the "severe" health‑risk category, prompting the Delhi Pollution Control Committee to issue advisories for vulnerable groups, including children, the elderly and those with respiratory conditions.
Experts note that such spikes are typical during the post‑monsoon to winter transition, when stagnant air and lower temperatures trap pollutants. Authorities continue to monitor the situation and have urged residents to limit outdoor activities while the AQI remains elevated.
