Over 7 pc of daily deaths in 10 Indian cities linked to PM2.5 pollution: Lancet study
New Delhi (PTI): On average, 7.2 per cent of all daily deaths in 10 of the largest and most polluted cities in India, including Delhi, Bengaluru and Mumbai, were linked to PM2.5 levels higher than World Health Organization (WHO) guidelines for safe exposure, according to a study published in The Lancet Planetary Health journal.
Delhi was found to have the largest fraction of daily and yearly deaths attributable to PM2.5 air pollution, caused by particles sized 2.5 micrometres or less in diameter.
Sources of such pollution include vehicular and industrial emissions.
Researchers said that daily exposure to PM2.5 pollution in Indian cities is linked with a higher risk of death, and locally created pollution could be possibly causing these deaths.
The international team included researchers from Varanasi’s Banaras Hindu University and the Centre for Chronic Disease Control, New Delhi.
They found that an increase of 10 micrograms per cubic metre in the average of fine particulate matter (PM2.5) pollution measured over two days (short-term exposure) was related to 1.4 per cent higher daily mortality.
The death risk was found to be doubled (2.7 per cent) per a 10 microgram per cubic metre increase, when the researchers restricted their analysis to observations below Indian standards of air quality, less stringent than WHO guidelines for safe exposure, which prescribe 15 micrograms per cubic metre of PM2.5 over a 24-hour period.
Indian air quality standards prescribe 60 micrograms per cubic metre of PM2.5 over a 24-hour period.
City-wise, the authors found a 0.31 per cent rise in daily mortality per a 10 micrograms per cubic metre increase in PM2.5 in Delhi, while in Bengaluru, the rise was 3.06 per cent.
The links between daily exposure to PM2.5 pollution and locally created pollutants were found to be stronger in models which the researchers used to explore cause-and-effect relationships.
Therefore, it was possible that the locally generated pollutants were causing these excess deaths, the authors said.
"The causal effects were especially strong in cities with lower concentrations of air pollution, such as (Bengaluru), Chennai, and Shimla," the authors wrote.
The study, "the first multi-city, time series analysis of short-term exposure to PM2.5 and daily mortality in India," looked at roughly 36 lakh daily deaths across ten Indian cities between 2008 and 2019. Other cities included in the analysis were Ahmedabad, Hyderabad, Kolkata, Pune, Shimla and Varanasi.

Riyan Parag debuts as first Assam cricketer in national team
Guwahati, Jul 6: All-rounder Riyan Parag became the first cricketer from Assam to play for the national team at the senior level as he made his debut against Zimbabwe in a T-20 tie at Harare on Saturday.
“A son's dream takes flight, and a father's heart swells with pride! Riyan Parag, you've made Assam proud! And what makes it even more special is receiving his Cap from the person who inspired him the most - his father!,” Assam Cricket Association posted on X, congratulating the young player.
Union minister Sarbananda Sonowal termed it a historic day for the state.
“Our very own @ParagRiyan makes his debut in the Indian Cricket Team as he plays his first T20I match for #TeamIndia against Zimbabwe at Harare,” he wrote on the micro-blogging site.
“#RiyanParag becomes the first Assamese male cricketer to play for India. Proud moment; may be reach the pinnacle of sporting glory,” the former Assam CM added.
The 22-year-old, who did not bowl in his first international match, failed to impress with the bat, being caught out for 2 runs off 3 balls in the fifth over as India chased Zimbabwe’s score of 115 runs.
Zimbabwe pulled off an upset of massive proportions when they stunned the Indian team brimming with an array of Next-Gen stars by 13 runs in the first T20I of the five-match series here on Saturday.
Riyan, who was a part of the Indian Under-19 team that won the 2018 Under-19 Cricket World Cup, was named in the Indian national squad for the Zimbabwe tour last month.
He has been representing Assam in domestic cricket since 2017 and has been a member of the Rajasthan Royals in the Indian Premier League since 2018.
Another cricketer from the state, Uma Chetry, had been earlier named in the Indian women's team but is yet to make her international debut.
