The air quality in the national capital improved from the 'severe' to the 'very poor' category on Sunday morning.


At 8 am, the Air Quality Index (AQI) was recorded at 357, falling under the 'very poor' category, compared to the 24-hour average AQI of 412 at 4 pm on Saturday, according to the Central Pollution Control Board.


However, Anand Vihar remained in the 'severe' category with an AQI of 404.


Delhi's air quality has remained hazardous for nearly a month. On October 30, it first slipped into the 'very poor' category and stayed there for 15 days. It worsened further last Sunday as Delhi recorded 'severe' air quality and stayed so on Monday and Tuesday.

By Wednesday, the air quality was in the 'severe plus' category. Favorable wind conditions brought slight relief on Thursday but the air quality began deteriorating again, nearing the 'severe' category, on Friday. Delhi's air quality slipped back to the 'severe' category on Saturday.

The 'severe' category poses serious health risks, especially due to fine particulate matter (PM2.5), which can penetrate deep into the lungs and enter the bloodstream, causing long-term health issues.

The weather office said the minimum temperature was recorded at 12 degrees Celsius. It has forecast shallow fog during the morning or night hours, with the maximum temperature expected to hover around 28 degrees Celsius.

The humidity level at 8:30 am stood at a high 75 percent.

Earlier this week, the Supreme Court directed the Delhi government and Police to immediately set up checkpoints on all 113 entry points to Delhi to check the entry of trucks in the national capital. It appointed 13 members of the Bar as court commissioners to visit the entry points to Delhi and verify whether entry of trucks is being stopped.

The apex court expressed dissatisfaction with the compliance of GRAP IV measures saying despite orders passed by the apex court and CAQM, there is a failure on the part of the Delhi government and Police to comply with clauses under GRAP stage IV.

"So far as complaince is concerned, we are not satisfied. Government has not stated clearly as to at how many entry points there are officers present to comply with measures of GRAP IV," it said.

"We direct the Delhi Government and Delhi Police to ensure that checkposts are immediately set up at all 113 entry points," the bench ordered.

As per the GRAP-IV restrictions imposed by the Commission for Air Quality Management (CAQM), the entry of trucks is prohibited to Delhi-NCR to combat air pollution.

Keeping in view the rising level of pollution, the Commission for Air Quality Management (CAQM) activated Stage-IV of the Graded Response Action Plan (GRAP), imposing restrictions like bans on truck entry and a halt to public construction projects.

Delhi Environment Minister Gopal Rai has urged Chief Secretary Dharmendra for strict enforcement of the Graded Response Action Plan (GRAP) to address the worsening air quality in the national capital. The minister highlighted the need for coordinated efforts in all departments to implement the Winter Action Plan-2024 and achieve sustained improvements in air quality.

Rai directed that all departments should also submit daily reports on actions taken and the progress made in implementing GRAP. He stressed the importance of strict enforcement mechanisms to penalize violators of air pollution norms.
