In pictures | Delhi air quality improves further, but still ‘very poor’
The Hindu
Delhi’s air pollution levels ameliorated marginally to the lower end of the “very poor” category on Sunday primarily due to favourable wind speed and a drop in the contribution of stubble burning. The 24-hour average air quality index stood at 339 at 4 pm, dropping from 381 a day ago. It was 447 on Friday, according to the Central Pollution Control Board. It had jumped to 450 on Thursday, just a notch short of the ‘severe plus’ category, prompting authorities to invoke the final stage of anti-pollution curbs, including a ban on non-BS VI diesel light motor vehicles.
