New Delhi: The city’s air quality deteriorated on Saturday and authorities have predicted a further dip in air quality in the days to come.

The AQI in different areas of Delhi on Saturday were: Bawana 258 (poor), Ashok Vihar 288 (poor), Dwarka Sector 8-303 (very poor), ITO 271 (poor).

AQI between 0-50 — good
AQI between 51-100 — satisfactory
AQI between 101-200 — moderate
AQI between 201-300 — poor
AQI between 301-400 — very poor
AQI between 401-500 — severe

According to the authorities, the change in direction of the wind has brought about the change. The wind, currently, is flowing from stubble-burning areas in Punjab and Haryana.

NASA satellites have picked-up several 'red spots' inside Delhi over the past couple of days, indicating that waste-burning in the open, despite a ban, is still rampant in the national capital.

Such incidents could worsen Delhi's already deteriorating air quality, and the EPCA has asked the Delhi Pollution Control Committee (DPCC) and other government agencies to step up their scrutiny.
