NEW DELHI: Delhi's air quality remained 'poor' on Monday (November 30) and is likely to deteriorate further amid a dip in the mercury and the wind speed.
The city's (AQI) on Monday stood at 259 at 7:00 am; whereas in Noida, the AQI was registered in 'very poor' category at 303. In Gurugram, the AQI was in 'poor' category in 225.
On November 29 (Sunday), the city's 24-hour average air quality index (AQI) in Delhi was 268. It was 231 on Saturday, 137 on Friday, 302 on Thursday and 413 on Wednesday.
An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.
The CPCB states that an AQI in the 'poor' category may cause breathing discomfort to most people on prolonged exposure.
The minimum temperature was seven degrees Celsius on Sunday and the maximum 26.4 degrees Celsius, the weather department said.
Calm winds and low temperatures trap pollutants close to the ground, while favourable wind speed helps in their dispersion.
The share of stubble burning in Delhi's pollution has also reduced significantly as the harvesting season has ended.
The contribution of stubble burning in neighbouring states to Delhi's PM2.5 levels was six per cent on Sunday, four per cent on Saturday, two percent on Friday and just one per cent on Thursday, according to the Ministry of Earth Sciences' air quality monitor, SAFAR.
