Delhi wakes up to 'Severe' air on morning after Diwali, AQI crosses 400 in several areas

Delhi woke up to a toxic haze on Diwali morning, with the capital's overall Air Quality Index (AQI) at 384, just short of the "severe" category, according to Central Pollution Control Board (CPCB) data. The 6 am update showed the picture was worse at many individual stations. Eleven of the 23 monitoring stations listed crossed 400, the threshold for "severe" air. The other 12 were in the "very poor" band of 301 to 400. Punjabi Bagh recorded the city's highest reading at 450, followed by RK Puram at 449 and IIT Delhi at 446. Chandni Chowk and Delhi University's North Campus both logged 423, Pusa 415, Burari Crossing 411 and NSUT Jaffarpur 409. The deterioration began before the festival. Saturday's 24-hour average of 369 made it Delhi's most polluted Diwali eve in a decade, though it was slightly below Friday's 382.

Delhi's AQI crosses 400 ahead of Diwali, toxic haze engulfs parts of NCR

In order to tackle the winter pollution and improve air quality over the coming months in the national capital, new rules regarding the entry of vehicles and construction work kicked in on Sunday, Nov 1. The Delhi government authorities also imposed penalties and environmental compensation totalling Rs 68.4 lakh on the first day of the Winter Action Plan. Also, several vehicles were turned back at border points and 566 challans were issued for violation of Pollution Under Control Certificate (PUCC) norms. But all the effort seems to have gone in vain as pollution levels intensified on Monday.&nbsp;The Air Quality Index (AQI) at ITO was 349, which is in the ‘very poor’ category, according to the Central Pollution Control Board (CPCB).

In order to tackle the winter pollution and improve air quality over the coming months in the national capital, new rules regarding the entry of vehicles and construction work kicked in on Sunday, Nov 1. The Delhi government authorities also imposed penalties and environmental compensation totalling Rs 68.4 lakh on the first day of the Winter Action Plan. Also, several vehicles were turned back at border points and 566 challans were issued for violation of Pollution Under Control Certificate (PUCC) norms. But all the effort seems to have gone in vain as pollution levels intensified on Monday. The Air Quality Index (AQI) at ITO was 349, which is in the ‘very poor’ category, according to the Central Pollution Control Board (CPCB).

Delhi's air turns 'very poor', AQI hits 349 despite Winter Action Plan

Delhi air quality has always been a concern, particularly during winters. And the burning of farm stubble in neighbouring Haryana and parts of Uttar Pradesh adds up to the woes. On Saturday (Oct 24), Delhi’s air quality remained in the ‘poor’ category, with an overall Air Quality Index (AQI) of 180, according to the latest data.&nbsp;It is for the third consecutive day that national capital is witnessing poor air quality.

Delhi witnesses poor air quality for third consecutive day, immediate relief unlikely

With winter approaching, Delhiites are preparing for pollution and dangerous AQI levels that plague the Indian national capital every year. In an attempt to keep the AQI levels in check, older goods vehicles carrying essential commodities will no longer be exempt from Delhi-NCR's pollution curbs once the two strictest stages of the Graded Response Action Plan (GRAP) are imposed. The Commission for Air Quality Management (CAQM) has removed the exemption for BS-IV and below vehicles under GRAP Stages III and IV as part of a revised schedule approved by the CAQM Full Commission on Monday.The change means light and medium goods vehicles (LGVs and MGVs) will face restrictions under Stage III, while trucks and heavy goods vehicles (HGVs) will be covered by the stricter Stage IV measures.Also read | <a href="https://www.wionews.com/india-news/delhi-pollution-plan-government-announces-50-wfh-higher-parking-charges-from-november-1-and-construction-ban-1790588775443">Delhi pollution plan: Government announces 50% WFH, higher parking charges from November 1 and construction ban</a><h2>Older goods vehicles face tighter entry rules</h2>Notably, the restrictions are not entirely new.

Delhi tightens pollution rules ahead of winter, BS-IV and older goods vehicles face fresh curbs: All you need to know

Delhi achieved a rare environmental milestone on the afternoon of July 9, recording a daily average Air Quality Index (AQI) of 48. According to the Commission for Air Quality Management, this marks the capital's lowest daily average AQI of 2026 and its very first "good" air day of the year. The last time the city witnessed such clean air was nearly three years ago, on September 10, 2023. The Central Pollution Control Board classifies an AQI between 0 and 50 as “good”, the cleanest category on India's scale, which Delhi seldom sees. The respite was brief, as the AQI stood at 54 on Friday and recorded 99 on Saturday. Meanwhile, Delhi was the most polluted capital on Earth in 2024, marking an average of 108 micrograms of these particles per cubic metre, over 20 times the recommended ceiling of 5 micrograms per cubic metre, marked by the World Health Organisation (WHO), according to the IQAir World Air Quality Report.&nbsp;Also read: <a href="https://www.wionews.com/india-news/why-are-indians-being-forced-to-buy-e20-and-can-t-choose-normal-petrol-e10-government-finally-answers-1783731750234">Why are Indians being forced to buy E20 petrol?

This mid-air capture of the fine particles is known as below-cloud scavenging. Basically, rain effectively chokes off dust at its source by soaking roadways and construction sites, while powerful monsoon winds disperse any remaining pollutants rather than allowing them to settle over the city. A study published in the Journal of Environmental Sciences highlights that heavy and sustained downpours drastically improve pollutant removal, whereas a light drizzle can actually increase PM2.5 concentrations. In damp air, fine particles swell and multiply, so weak rain adds moisture without sweeping anything away. A separate analysis of Delhi's own weather, published in Environmental Monitoring and Assessment, confirmed that only moderate to heavy rainfall lands a real cleansing blow.&nbsp;

The Commission for Air Quality Management (CAQM) on Tuesday (May 19) invoked Stage I of the Graded Response Action Plan (GRAP) in Delhi-NCR after the air quality in the national capital worsened to the “poor” category. This comes as Delhi recorded a daily average Air Quality Index (AQI) of 208 on Tuesday. It added that the forecasts by the India Meteorological Department/Indian Institute of Tropical Meteorology have indicated that the air quality in the city is likely to remain in the “poor” category in the coming days.“The Commission for Air Quality Management (CAQM) on Tuesday invoked Stage-I of the Graded Response Action Plan (GRAP) across the National Capital Region (NCR) with immediate effect after Delhi’s daily average Air Quality Index (AQI) rose to 208, falling in the ‘Poor’ category,” the Ministry of Environment, Forest and Climate Change said in a statement.It added, “The decision was taken by the CAQM Sub-Committee on GRAP following a review of the current air quality scenario in Delhi-NCR and forecasts by IMD/IITM indicating that air quality is likely to remain in the ‘Poor’ category in the coming days.”The CAQM said all agencies concerned in Delhi-NCR must intensify monitoring and maintain high vigilance over dust pollution, vehicular emissions and industrial activities. The Commission also urged citizens to cooperate by reducing activities that contribute to air pollution.<h2>What’s under GRAP I measures?</h2>Under Stage I of GRAP, dust mitigation measures are implemented, and periodic mechanised sweeping and water sprinkling on roads is conducted. It also includes no illegal waste dumping in open areas and regular lifting of municipal construction and hazardous waste from dump sites.Additional measures include increased deployment of anti-smog guns and stricter dust-control efforts, along with a crackdown on open burning of biomass and municipal waste. Authorities will also intensify checks on vehicle pollution norms. The plan further enforces a complete ban on the use of coal and firewood in tandoors at hotels, restaurants and roadside eateries, allowing only electric or clean fuel-based cooking systems.

Delhi breathes a little easier: AQI improves to 221, remains in 'poor' category; GRAP IV revoked

Union Minister for Road Transport and Highways Nitin Gadkari on Tuesday acknowledged that the transport sector is a significant contributor to pollution and emphasised the urgent need to reduce India's dependence on fossil fuels. Gadkari’s comments came against the backdrop of a sharp deterioration in Delhi’s air quality, as a thick blanket of toxic smog engulfed the national capital.&nbsp;"If there is any true nationalism today, it is reducing imports and increasing exports. But look at our situation. I stayed in Delhi for two days and developed a throat infection. Delhi is troubled by pollution. I am the Road Transport Minister, and around 40 per cent of pollution is linked to our sector," Nitin Gadkari said, NDTV reported.&nbsp;He also highlighted the country’s heavy reliance on fossil fuels, noting that India spends nearly Rs 22 lakh crore annually on importing them. "What kind of nationalism is this? Fossil fuels are limited, and pollution is increasing. Can't we reduce fossil fuel usage? Why can't we promote electric vehicles and hydrogen-powered vehicles, which can lead to zero pollution?" he questioned.<h3>Delhi AQI stood at a ‘hazardous' level</h3>Meanwhile, the Air Quality Index (AQI) of Delhi stood at a hazardous level of 413 at around 8 am on Tuesday, severely impacting visibility and raising public health concerns. The Central Pollution Control Board (CPCB) showed 'severe' air quality levels across several parts of the National Capital Region (NCR).&nbsp;Anand Vihar emerged as one of the worst-affected areas with an AQI of 466, followed by Ashok Vihar at 444 and Chandni Chowk at 425. Areas around India Gate, Kartavya Path and Rashtrapati Bhavan were also shrouded in toxic smog, recording an AQI of 384, classified as 'Very Poor'.&nbsp;In response, the Commission for Air Quality Management (CAQM) invoked all measures under GRAP Stage-IV across Delhi-NCR. In addition, truck-mounted water sprinklers were positioned to suppress dust and curb particulate pollution as part of emergency steps.&nbsp;&nbsp;
