IIT-Bombay study calls for stringent policies to restrict vehicular pollution in India
New Delhi, July 24 (IANS) Stringent policies to restrict vehicular pollution are imperative to tackle the problems of increasing urban air pollution — a major health concern — in the country, said Indian Institute of Technology (IIT) Bombay researchers in a study on Wednesday.
Emissions from motor vehicles are major contributors to urban air pollution in India.
The longer time vehicles spend on the roads leads to a large amount of fuel being burned, thus resulting in more pollution.
However, the polluting characteristics of all vehicles are not the same as some vehicles release disproportionately higher amounts of pollutants.
The study investigated factors determining the characteristics of high-emitting vehicles, also known as super-emitters.
“Until now, there has been no study in India that has examined the share of super-emitters in real-world vehicular fleets. The previous studies assumed their share based on literature from other countries or secondary data. The motivation was to reduce uncertainty in the emission estimation from real-world vehicular fleets,” said Sohana Debbarma, a researcher who conducted the study.
The researchers explained that super-emitters were vehicles that were either old, poorly maintained, over-loaded heavy-duty vehicles or all of them.
They release significantly higher amounts of pollutants compared to other vehicles in the fleet.
According to the IIT-Bombay study, for light-duty vehicles (vehicles that weigh less than 3,500 kg such as cars, two-wheelers, three-wheelers, and light commercial goods vehicles), the age of the vehicles and the maintenance of the engine potentially determines whether the vehicle is a super-emitter.
In the case of heavy-duty vehicles (vehicles that weigh more than 3,500 kg, such as buses and trucks), the overloading condition, along with the age and maintenance of the vehicles, contribute to the disproportionately high pollutant emissions.
For the study, the team set up their pollutant-measuring equipment at the entry and exit of the Kamshet-I tunnel located on the Mumbai-Pune Expressway.
Along with exhaust emissions (resulting from incomplete combustion of fossil fuels), non-exhaust emissions (resulting from brake wear, tyre wear, road surface wear, and resuspension of road dust) were also collected.
The traffic data was collected using high-definition video cameras and the vehicle registration numbers data (collected manually).
The study collected data over two weeks.
The researchers identified super-emitters through manual inspection based on the video surveillance records of the traffic passing through the tunnel.
“Vehicles that emitted a visible plume of smoke or appeared to be overloaded were identified as super-emitters. It was also validated using the information on the age of the vehicles and type of emission technology: Bharat Stages (BS) – II, III, and IV (the study was conducted in 2019 when there were no BS VI vehicles) and the type of fuel (petrol, diesel, and CNG),” the team said.

Defence Ministry: Year 2025 will be year of reforms
On Wednesday, the Defence Ministry announced that 2025 will be designated as the “Year of Reforms,” with a primary focus on establishing integrated theatre commands to enhance collaboration among the three branches of the military.
These reforms are aimed at transforming the armed forces into a technologically advanced, combat-ready force capable of executing multi-domain integrated operations, the ministry stated.
The initiative will emphasize emerging domains such as cyber and space, alongside cutting-edge technologies like artificial intelligence, machine learning, hypersonics, and robotics.
Defence Minister Rajnath Singh described the “Year of Reforms” as a pivotal milestone in the modernization of the armed forces.
“It will set the stage for significant advancements in the nation’s defense capabilities, ensuring the security and sovereignty of India in the face of 21st-century challenges,” he said.

A 3.2 magnitude tremor struck Gujarat’s Kutch district on Wednesday morning
A 3.2 magnitude tremor struck Gujarat’s Kutch district on Wednesday morning, according to the Institute of Seismological Research (ISR).
The district administration reported no casualties or property damage following the quake.
The tremor occurred at 10:24 am, with its epicenter located 23 kilometers north-northeast (NNE) of Bhachau, as per the Gandhinagar-based ISR.
Last month, the region experienced four seismic events exceeding a magnitude of 3, including a 3.2 magnitude tremor just three days ago, with its epicenter also near Bhachau.
Earlier tremors in the area included a 3.7 magnitude earthquake on December 23 and a 3.2 magnitude event on December 7, according to ISR reports.
Kutch was also jolted by a 4.0 magnitude earthquake on November 18, 2024. On November 15, a 4.2 magnitude quake hit Patan in north Gujarat, based on ISR data.
Gujarat is considered a high-risk earthquake zone, having experienced nine major earthquakes over the past 200 years, according to the Gujarat State Disaster Management Authority (GSDMA). The 2001 earthquake in Kutch, which occurred on January 26, was the third-largest and second-most destructive in India in the last two centuries, according to the GSDMA.

Diljit Dosanjh faces legal action over concert songs
Singer and actor Diljit Dosanjh’s much-anticipated New Year’s Eve concert in Ludhiana faced legal hurdles after a complaint was filed by Punditrao Dharenavar, an assistant professor from Chandigarh.
Following the complaint, the Deputy Director of the Women and Child Department, Government of Punjab, issued a formal notice to Ludhiana’s District Commissioner, urging them to prohibit Dosanjh from performing specific songs during his live show on December 31, 2024.
The notice specifically targets songs accused of promoting alcohol, including Patiala Peg, 5 Tara Theke, and Case (Jeeb Vicho Feem Labbiya), even if the lyrics are slightly modified. The complaint points to previous warnings issued to Dosanjh by various commissions advising against performing these controversial tracks.
Despite these warnings, the singer allegedly continues to perform the songs with minor alterations. Dharenavar raised serious concerns about the influence of such music on young audiences, especially when minors are present at live events.
Adding to the controversy, Dharenavar referenced a 2019 Punjab and Haryana High Court ruling, which directed law enforcement to ensure that songs promoting alcohol, drugs, or violence are not played at public events, including concerts. This ruling underscores the legal basis for the complaint and has further intensified the scrutiny surrounding the event.

Suchir Balaji’s mother alleges Murder
The mother of Suchir Balaji, a 26-year-old former OpenAI researcher found dead after accusing the company of copyright violations, has alleged that her son was “murdered” and called for a Federal Bureau of Investigation (FBI) probe.
Poornima Rao, Suchir’s mother, claimed her son’s death was a “cold-blooded murder” that authorities wrongly ruled as suicide. She further disclosed that a private autopsy report conflicted with the findings of the initial police investigation.
Rao alleged that her son’s apartment had been “ransacked” and cited evidence of a struggle in the bathroom, including bloodstains that suggested he had been assaulted.
“We hired a private investigator and conducted a second autopsy to uncover the truth. The private autopsy does not confirm the cause of death stated by the police. Suchir’s apartment was ransacked, there were signs of a struggle in the bathroom, and it appears he was hit based on blood spots. This is a cold-blooded murder being misclassified as a suicide. Lobbying in San Francisco won’t deter us from seeking justice. We demand an FBI investigation,” Rao wrote on X.
Elon Musk reacted to Rao’s post, commenting, “This doesn’t seem like a suicide.”
Balaji was discovered dead in his San Francisco apartment months after accusing OpenAI of violating copyright laws during the development of ChatGPT, as reported by Fox News. Despite these claims, the San Francisco Police Department found no evidence of foul play and ruled the death a suicide.
On October 24, shortly before his death, Balaji voiced doubts about the “fair use” defense in generative artificial intelligence. “I recently participated in a NYT story about fair use and generative AI, and why I’m skeptical ‘fair use’ would be a plausible defense for a lot of generative AI products,” he wrote on X.
