Diwali: Delhi’s air quality very poor, likely to become ‘severe’ by night

Delhi’s air quality remained very poor on Saturday morning and emission from firecrackers and calm winds may push it to the severe zone. The Ministry of Earth Sciences’ air quality monitor, SAFAR, said the PM2.5 concentration in Delhi on Diwali is likely to be the lowest in the last four years.

Two factors smoke from farm fires and stagnant surface winds will keep the air quality in the higher end of the very poor category.
