The air quality in Delhi remained in the severe category on Thursday morning, with a thick haze lingering over the national capital for the third consecutive day. At 8 am, the city's overall air quality index stood at 408, a tad better than 415 at 8 pm on Wednesday. Twenty-two of the 37 air quality monitoring stations across Delhi recorded the air quality in the severe category on Thursday morning. Anand Vihar continued to be the most-polluted area with an AQI of 466, followed by Wazirpur with an AQI of 453. According to SAFAR, the share of stubble burning in Delhi's pollution rose to 35% on Wednesday, the season's highest, and the hazardous haze shrouding the city could "purely" be attributed to it.
