While the AQI continues to remain in the 'severe' category, Stage 2 of the GRAP is in effect. In response to the situation, the BJP recently urged the Delhi government to urgently close all schools up to Class 5, a condition covered under GRAP 3
Delhi continued to experience ‘severe’ air quality on Thursday, a day after the national capital recorded the worst Air Quality Index (AQI) in the country. The AQI level stood at 432 in the morning on Thursday, according to the Central Pollution Control Board (CPCB).
In response to the situation, the Bharatiya Janata Party recently urged the Delhi government to urgently close all schools up to Class 5. The party also criticised the Aam Aadmi Party (AAP) for failing to manage the situation effectively.
Despite these alarming AQI levels, Stage 3 of the Graded Response Action Plan (GRAP) has not yet been implemented. According to the Commission for Air Quality Management in NCR and adjoining areas, Delhi's AQI must fall between 401-450 to trigger GRAP 3.
Stage 3 of GRAP allows states to conduct online classes by suspending in-person classes for students up to Class 5 and promotes enhanced public transportation.
Currently, GRAP Stage 2 is in effect, which recommends mechanical sweeping and water sprinkling on identified roads. Other measures, such as implementing dust control at construction and demolition sites, are also part of the plan.
The AQI was categorised as 'severe' for the first time this season on Wednesday. The central pollution watchdog attributed the deterioration to an “unprecedentedly dense” fog, describing it as an “episodic event”.
Together, PM 2.5 and PM 10 — two predominant microscopic pollutants — mix with the fog to form dense smog, causing life-threatening respiratory issues currently being experienced by the city.
As a result of the smog and reduced visibility, about 10 flights were diverted from Delhi Airport on Wednesday. However, all flight operations are normal according to the Delhi Airport's advisory shared on Thursday.
Delhi has been battling pollution for the past 14 days following Diwali, without any signs of improvement.
Meanwhile, data from IQAir shows Lahore as the most polluted city, with an AQI of 1537. UNICEF has urged Pakistan to take urgent action in response.
