Crackers, farm fires may push Delhi's air quality to 'severe' zone on Diwali

Delhi's air quality may enter the 'severe' zone on Diwali if there are any firecracker-related emissions on the occassion and stubble burning might contribute to the lower air quality too.

Delhi's air quality is likely to enter the 'severe' zone on Diwali night and the share of stubble burning in its PM2.5 pollution may go up to 40 per cent the day after, according to the Ministry of Earth Sciences' air quality forecast agency SAFAR.

Under the zero firecracker emission scenario, Delhi's PM2.5 concentration is predicted to be in the upper end of the 'very poor' category from November 4 to November 6.
