AQI up from 'very poor' to 'poor', experts say not for long

New Delhi: Delhi's air quality showed signs of improvement on Monday as it moved from 'very poor' to 'poor' category, but experts said it might deteriorate in the coming days due to the toxic air coming out of a fire at Bhalaswa landfill site.

The Central Pollution Control Board recorded the overall Air Quality Index (AQI) of Delhi at 272 in the evening.

However, a fire has been raging at the Bhalswa landfill site here since October 20.

Three fire tenders were working to douse the blaze, which was finally "almost" brought under control by 7.30 pm on Monday, a Delhi Fire Service official said.

On Sunday, the AQI had oscillated between "poor" and "very poor" categories.

Faridabad and Gurgaon recorded 'poor' air quality; Noida and Greater Noida too reported 'poor' air quality while Ghaziabad reported 'very poor' category. Saturday saw the season's worst air quality reading at 324.
