Smog cover over Delhi-NCR; air quality severe amid unhelpful meteorological conditions
New Delhi(PTI): A layer of smog shrouded Delhi-NCR on Thursday and partially blotted out the sun on Chhath Puja as the air quality slipped back into the severe zone with unfavourable meteorological conditions aiding accumulation of pollutants, authorities said.
Green think tank Centre for Science and Environment (CSE) said the ongoing smog episode is a public health emergency.
"This requires urgent emergency action on key combustion sources (vehicles, industry, waste burning) and dust sources (construction and roads) to prevent further trapping of pollution when there is no wind to blow this away," said Anumita Roychowdhury, executive director, research and advocacy, CSE.
At 10 am, Delhi recorded an Air Quality Index (AQI) of 407. Thirty-three of the 39 air quality monitoring stations in the national capital recorded air pollution levels in the severe category.
The 24-hour average AQI was 372 on Wednesday.
Ghaziabad (454), Greater Noida (404) and Noida (426) also recorded severe air quality at 10 am.
An AQI between zero and 50 is considered "good", 51 and 100 "satisfactory", 101 and 200 "moderate", 201 and 300 "poor", 301 and 400 "very poor", and 401 and 500 "severe".
An official from the India Meteorological Department (IMD) said shallow fog and low temperatures in the morning -- Delhi recorded the season's lowest temperature of 12.6 degrees Celsius on Thursday -- trapped pollutants close to the ground and calm winds led to stagnant conditions.
Visibility levels at the Indira Gandhi International Airport and the Safdarjung Airport dropped to 600-800 metres, he added.
The CSE said the current severe smog episode in Delhi-NCR is expected to last for two more days.
It also said the average daily contribution of smoke from farm fires from the middle of October to November 8 was the lowest in four years.
"Compared to the first smog episode of the previous four years, the current smog has matched the duration of the first smog of 2018 and 2020 season -- both lasted six days. If conditions do not improve, it might overtake the 2019 smog that lasted eight days," the CSE said.
The longer duration of this year's smog despite relatively windier local conditions might be due to a lack of pollution control measures in the city, the green think tank said.
On an average, the contribution of smoke to Delhi's daily PM2.5 from the middle of October to November 8 was the lowest in the last four years.
"So far, it has recorded an average of 12 per cent (farm fire share) per day in contrast to 17 per cent per day in 2020, 14 per cent per day in 2019 and 16 per cent per day in 2018 (as reported by SAFAR)," the CSE said.
The share of farm fires in Delhi's pollution rose to 48 per cent on Sunday, the highest since November 5, 2018, when it was recorded at 58 per cent.
Last year, the share of stubble burning in Delhi's pollution had peaked at 42 per cent on November 5. In 2019, crop residue burning accounted for 44 per cent of Delhi's PM2.5 pollution on November 1.

Passenger slapped during panic attack on IndiGo flight, sparks outrage on social media
Mumbai/Kolkata/Silchar: A shocking incident aboard IndiGo flight 6E138 from Mumbai to Kolkata has gone viral, sparking outrage after a video emerged showing a man being slapped mid-flight while reportedly suffering a panic attack. The victim, identified as Hossain Ahmed Mazumdar from Assam, has since gone missing, and his family is seeking urgent answers.
The video, widely circulated on social media, shows Hossain in visible distress, attempting to leave his seat and reportedly requesting to deboard. As flight attendants tried to calm him down, another passenger suddenly approached and slapped him. The incident triggered immediate protest from fellow travellers.
A young man suffers a panic attack, his co passenger slaps him. Indigo airlines says “All appropriate regulatory agencies have been duly informed, in line with protocol.”

This is a criminal case and the man needs to be on a No Fly List @DGCAIndia pic.twitter.com/dY1gQC6ze0
Hossain, a gym trainer based in Mumbai, was en route to his hometown Katigorah in Cachar district via a connecting flight from Kolkata to Silchar. However, he never boarded the Silchar flight, and his mobile phone remains unreachable. His family, who had gathered at the Silchar airport, are now in distress. Zubairul Islam Mazumdar, a relative, said, “We have no idea where he is. We’ve contacted the police and airport authorities but haven’t received any concrete information.” His father, Abdul Mannan Mazumdar, who is undergoing cancer treatment, said tearfully, “He was our only hope. Now we don’t even know if he’s safe.” In a statement issued on August 1, IndiGo Airlines said: “We are aware of an incident involving a physical altercation on board one of our flights. Such unruly behaviour is completely unacceptable, and we strongly condemn any actions that compromise the safety and dignity of our passengers and crew. Our crew acted in accordance with established procedures. The individual identified as unruly was handed over to the security authorities upon arrival. Regulatory agencies have been informed as per protocol.”

However, the airline's statement has been criticised for failing to clarify what happened to Hossain after the incident, whether he received medical help, was detained, or was allowed to continue his journey.
Weak kneed response from @IndiGo6E . Has the man who got physical with a fellow passenger been put on a no-fly list? Has Indigo followed up on its complaint at point of disembarkation? If the passenger was handed over to the @CISFAirport were charges pressed? pic.twitter.com/qXMnfiBbFE

The video triggered widespread anger on social media, with many users interpreting the slap as a possible hate-driven act. However, aviation journalist Jagriti Chandra of The Hindu offered a clarification on X, stating: “The passenger who assaulted a co-passenger aboard IndiGo flight was handed over to law enforcement agencies for unruly conduct. Incident occurred after one passenger was feeling uncomfortable in the flight and wanted to deboard. Both belong to the same religious community.”

Despite this clarification, concerns remain about the airline's handling of a visibly distressed passenger, particularly in the context of mental health. Unverified posts circulating on social media claim that Hossain was later found, though there has been no official confirmation from authorities or the airline.
Alhamdulillah! Hussain Ahmed Mazumder, who was assaulted on an IndiGo flight while returning from Mumbai to Silchar and went missing, has now been found safe in Kolkata.
