Delhi's AQI crosses 300 for first time this season, more smog expected in coming days

Delhi's air quality plummeted to a "very poor" rating on Monday despite recent curbs, with the Air Quality Index (AQI) soaring above 300. The AQI in Delhi and neighboring Noida breached the "very poor" threshold, with readings of 310 and 311 respectively, according to the Central Pollution Control Board (CPCB). Visuals captured the smog enveloping the city, particularly around areas like Central Delhi and India Gate.

Ghaziabad and Gurugram, meanwhile, faced "poor" air quality with AQI levels of 278 and 230. Faridabad, however, recorded a comparatively better AQI of 116, placing it in the "moderate" category. The CPCB app issued health advisories, warning that prolonged exposure to such conditions could lead to respiratory illnesses. The deteriorating air quality in Delhi has been attributed to a combination of factors, including farm fires, weather conditions, and Diwali celebrations.

Despite Delhi tightening vehicle-entry restrictions under the revised Graded Response Action Plan (GRAP) from November 1, the air quality has continued to worsen. The GRAP measures aim to improve the situation by restricting non-compliant vehicles, including petrol and diesel cars and commercial goods vehicles, from entering the capital.
