NEW DELHI: Delhi’s air quality remained in the ‘severe’ category on Sunday because of the large influx of stubble-related pollutants, apparently, from a much higher effective fire count, authorities said.
According to the Central Pollution Control Board (CPCB) data, the city’s air quality index (AQI) stood at 416 (severe) at 8 pm. Chief Minister Arvind Kejriwal also tweeted about the air pollution situation and shared data.
“Nov 7 – AQI – 428 (401 to 500 – Severe) PM10 – 450 (Above 430 – Severe) PM2.5 – 309 (Above 250 – Severe),” he tweeted.
Strong surface winds had slightly improved Delhi’s air quality on Saturday but it had remained in the ‘severe’ category as the contribution of farm fires in the city’s PM2.5 pollution had reached the season’s highest of 41 per cent.
