| In Delhi air pollution gone beyond expected as ongoing test cricket match between Sri Lanka and India. The national capital since last week has witnessed a crisp drop in temperature in the wake of the winter season in India, but unfortunately, the city's air pollution levels continue to rise. It has been learn that the air quality in Delhi continues to lounge in the 'very poor' category, with conspicuous pollutants remained above normal standards at most locations on Sunday. It must be noted that the Air Quality Index in the national capital had improved significantly after the AAP government imposed certain measures to curb the emergency situation declared by the Indian Medical Association earlier. However, the pollution levels are slowly rising again, in line with the predictions shared by the weather department on November 30.
While here in Delhi the rise in PM2.5 and PM10 levels were again ascertained on the last days of November, it again started to descend rapidly starting December. On December 1, the concentration of suspended particulate matter PM10 climbed to 412 micro grams per cubic metre (ug/m3) during the day. PM2.5 was recorded at 200 ug/m3. The last time the level of PM10 was this high was on November 14, when Delhi had just come out of a week-long spell of emergency levels of pollution. The 24-hour safe averages of these ultrafine particulates are 60 (PM2.5) and 100 (PM10).
The CPCB attributed the rise in the air pollution level to calm conditions marked by a fall in wind speed and the incursion of moisture in the air, conditions which favour accumulation of particulates. The air quality index (AQI) of CPCB for Delhi was in the 'very poor' category with a score of 343 on a scale of 500.
