Tuesday morning in Delhi saw the mercury level drop and air quality index rise with the Met department predicting a partly cloudy sky during the day.
Pollution levels rose again in the national capital with the AQI — a measure of pollutants in the air — climbing to a poor 274 (on a scale of 500) at 8.30am, from Monday’s 24-hour average of 234. Sunday’s promise of respite, when the AQI had dropped to a moderate 197, seems to have been short lived.
Areas close to Anand Vihar were the most polluted with an AQI of 356, categorised as very poor. The primary pollutant here was the finer and more dangerous particulate matter PM 2.5.
The Delhi Technical University, ITO, RK Puram, Siri Fort, Punjabi Bagh, and Netaji Subhash Institute of Technology in Dwarka, also had very poor air according to the data collated by the Central Pollution Control Board (CPCB).
