Delhi’s air quality remains ‘severe’ for second day after Diwali; likely to improve by Saturday say agencies
The overall air quality index (AQI) was recorded at 426 which falls in the 'severe' category, according to data by the Central Pollution Control Board (CPCB).
The Centre-run System of Air Quality and Weather Forecasting And Research (SAFAR) said the city's air quality has "improved significantly" since Thursday, but the recovery was slow due to low surface wind speed.
