Delhi’s air quality has been very bad till now and it continued to worsen through late Tuesday night, straying deeper into the ‘severe’ zone by Wednesday morning.
Central Pollution Control Board (CPCB) data shows that at 6.40am, the average air quality index (AQI) of Delhi reached 457. On Tuesday, the overall AQI of the city was recorded 425.
Scientists and weather experts said that low wind speed will continue to impact the national capital’s air quality till Thursday, with a possibility of the levels dipping further to reach ‘severe+’ category by tomorrow.
The change in wind direction from easterly to north-westerly in the last two days has also pushed toxic smoke from the neighbouring states of Punjab and Haryana, where crop stubble burning incidents are on a high.
