New Delhi, Oct 30 (PTI): Delhi recorded its air quality in the 'very poor' category on Sunday morning and forecasters said slow wind speed and an increase in stubble burning, especially in Punjab, may push it to the 'severe' zone.
With pollution levels worsening, the Centre's air quality panel on Saturday directed authorities to impose a ban on construction and demolition activities in Delhi-NCR, except in essential projects, and other curbs under stage III of the Graded Response Action Plan.
Delhi's overall air quality index (AQI) stood at 367 at 9 am. The 24-hour average AQI on Saturday was 397, the worst since January. It was 354 on Thursday, 271 on Wednesday, 302 on Tuesday and 312 on Monday (Diwali).
