Delhi's air quality worsens to near severe levels after Diwali

Delhi's air quality worsened on Sunday, with an Air Quality Index (AQI) of 382, nearing the 'severe' category. This decline follows a brief improvement after Diwali, attributed to falling temperatures and increased pollution from various sources. Other northern states, including Haryana and Punjab, also reported poor air quality. Cities like Bahadurpura, Muzaffarnagar, Noida, and Sonipat recorded AQI levels between 302 and 335, still below Delhi's levels. Overall, six cities, including Delhi and Noida, fell into the 'very poor' category, while over 50 cities remained in the 'poor' category, according to the Central Pollution Control Board.
