Delhi’s air quality dipped again on Friday to the very-poor category after slight improvement over the last few days. The air quality index (AQI) went into ‘very-poor’ category at 35 out of 37 monitoring stations.

The AQI stood at 382 in Jahangirpuri, 377 in Nehru Nagar and 372 each in NSIT Dwarka and Bawana. According to the data of the Central Pollution Control Board (CPCB), the 24-hour average air quality index (AQI) worsened to reach 346 from 295 a day ago.

The Commission for Air Quality Management said restrictions under stage III of the graded response action plan (Grap) would continue to remain in place in the National Capital Region as the air pollution in the area was showing an upward trend. “Wind conditions have not been very favourable and accordingly dispersion of air pollutants has not been very effective,” it said in a statement.
