NEW DELHI: Delhi’s air quality was recorded in the ‘poor’ category on Saturday (November 21) and is likely to deteriorate further amid a dip in the minimum temperature. A change in the wind direction has also increased the share of stubble burning in the city’s pollution slightly.

The overall Air Quality Index (AQI) soared to 313 in the morning and stood at 309 in the noon, as per the System of Air Quality and Weather Forecasting And Research (SAFAR).

According to Central Pollution Control Board data, the AQI was at 265 in Anand Vihar, 296 in Ashok Vihar, 271 in Old Delhi’s popular marketplace Chandni Chowk, 303 in Dwarka Sector 8 and 290 in RK Puram, all falling under the ‘poor’ category.

Temperatures were appreciably below normal at many places in Punjab, Haryana and Delhi on Nov 20, with the national capital recording a minimum of 7.5 degrees Celsius, the lowest in the month of November in 14 years.
