Delhi woke up to a thick blanket of smog on Sunday morning, with air quality levels plunging to severe levels, leaving residents grappling with poor visibility and health risks, reported ANI.

The dense haze, caused by a mix of local pollution and the seasonal crop burning in neighbouring states, choked the city's skies, triggering widespread concerns over Delhi's ongoing battle with air pollution.

According to the Central Pollution Control Board (CPCB), the national capital recorded an Air Quality Index (AQI) at 428 as of 8 am, placing it in the 'severe' category, reported ANI.

Visuals from around the New Delhi Railway Station show a thick layer of smog blanketing the entire area.

Likewise, drone visuals from the AIIMS area at 7.10 am show high-rise buildings in the area covered with smog, reducing visibility to the bare eyes, reported ANI.

Drone shots from Mayur Vihar at 7.30 am show a smog-filled atmosphere engulfing the area as pollution levels continue to remain high.

In Patparganj, the AQI was recorded at 439, categorized as 'severe' by the CPCB.

Meanwhile, the Delhi airport took to its official handle to inform the flyers that low-visibility procedures are currently underway, reported ANI.

"Low-visibility procedures are in progress at the Delhi airport. All flight operations are presently normal. Passengers are to contact the airline concerned for updated information," posted the handle on X.

As the pollution level continues to remain high, a thick froth of toxic foam primarily caused by untreated industrial effluents, sewage discharge, and high phosphate levels from detergents, was observed in sections of the river near Kalindi Kunj and Okhla Barrage.

The residents of Delhi continue to raise alarms as air quality levels in many areas remain in the "severe" category in multiple areas.

The AQI for Anand Vihar was recorded at 457, Bawana at 471, CRRI Mathura Road at 471, DTU at 386, Dwarka Sector-8 at 445, ITO at 411, Jahangirpuri at 466, Lodhi Road at 374, Mundka at 463, Narela 444, North Campus at 427, Punjabi bagh at 447, RK Puram at 434, Shadipur at 457 and Wazipur at 463, according to SAFAR-India (System of Air Quality and Weather Forecasting and Research), reported ANI.

The Delhi government implemented a ban on BS-III petrol and BS-IV diesel four-wheelers from plying under the Graded Response Action Plan (GRAP-III) in the national capital from Friday to combat deteriorating air quality, reported ANI.

As per the government order, violators will face prosecution under Section 194(1) of the Motor Vehicle Act, 1988, and a Rs 20,000 fine.

This comes after the Commission for Air Quality Management (CAQM) ordered the implementation of the Graded Response Action Plan (GRAP-III) in Delhi-NCR from Friday at 8 am to prevent further deterioration of air quality in the national capital region after the Air Quality Index (AQI) in Delhi worsened and reached the severe category, reported ANI.

GRAP III (Graded Response Action Plan) measures to mitigate the effects of air pollution in Delhi NCR include intensifying the frequency of mechanised sweeping of roads, daily water sprinkling along with dust suppressants, before peak traffic hours, on roads and right of ways including hotspots, heavy traffic corridors and proper disposal of the collected dust in designated sites, landfills.

Additionally, all demolition works, earthwork for excavation and filling including boring & drilling works, and any transportation of demolition waste are banned with the implementation of GRAP III measures to fight air pollution.

The Graded Response Action Plan (GRAP) for the National Capital Region (NCR) is classified into four different stages of adverse air quality in Delhi: Stage I -- 'poor' (AQI 201-300); Stage II -- 'very poor' (AQI 301-400); Stage III -- 'severe' (AQI 401-450); and Stage IV -- 'severe plus' (AQI >450).

This year, Stage III has been invoked much later than in 2023, when it was activated on November 2nd. The action plan, effective across the entire NCR, will supplement ongoing Stage-I and Stage-II measures already in place, reported ANI.

The 11-point action plan under Stage III includes increased road sweeping, intensified water sprinkling with dust suppressants in high-traffic areas, and enhanced public transport services with differential pricing to encourage off-peak travel.
