Air pollution shortens life by more than one year in India
New York, Aug 23 : If air pollution were removed as a risk for death, people in the world could live at least a year longer and in India, which is battling a severe air pollution, the benefit would be even more -- about 1.5 years, says study.
"Here, we were able to systematically identify how air pollution also substantially shortens lives around the world," said lead researcher Joshua Apte from The University of Texas at Austin in the US.
"What we found is that air pollution has a very large effect on survival -- on average about a year globally," Apte added.
For the study, published in the journal Environmental Science and Technology Letters, the researchers looked at outdoor air pollution from particulate matter (PM) smaller than 2.5 microns.
These fine particles that can come from power plants, cars and trucks, fires, agriculture and industrial emissions can enter deep into the lungs, and breathing PM2.5 is associated with increased risk of heart attacks, strokes, respiratory diseases and cancer.
The team used data from the Global Burden of Disease Study to measure PM2.5 air pollution exposure and its consequences in 185 countries.
They then quantified the national impact on life expectancy for each individual country as well as on a global scale.
"A body count saying 90,000 Americans or 1.1 million Indians die per year from air pollution is large but faceless," Apte said.
"Saying that, on average, a population lives a year less than they would have otherwise -- that is something relatable," he added.
In the context of other significant phenomena negatively affecting human survival rates, Apte said this is a big number.
"For example, it's considerably larger than the benefit in survival we might see if we found cures for both lung and breast cancer combined," he said.
"In countries like India and China, the benefit for elderly people of improving air quality would be especially large. For much of Asia, if air pollution were removed as a risk for death, 60-year-olds would have a 15 per cent to 20 per cent higher chance of living to age 85 or older," Apte said.

After six-year cancer battle, Chhattisgarh man cracks UPSC exam in third attempt
Mahasamund (PTI): Overcoming a six-year battle with cancer and resigning from three jobs, Sanjay Dahariya from Chhattisgarh's Mahasamund district has secured the 946th rank in the UPSC Civil Services Examination 2025 in his third attempt.
The 38-year-old son of a farmer from Beltukri has brought immense pride and joy to his family and the people of his village.
Dahariya's academic journey began at a local government school, but it took a significant turn when he was selected for Jawahar Navodaya Vidyalaya, Mana (Raipur), in Class 5.
The path to the civil services was fraught with professional and personal hurdles for Dahariya.

After a stint with the State Bank of India in West Bengal from 2009 to 2011, he resigned to focus on higher goals. However, in 2012, he was diagnosed with cancer in the salivary glands, leading to a gruelling treatment that lasted six years.
Undeterred, Dahariya, who also suffers from a minor vision impairment, continued his pursuit of civil services and kept his career on track with another stint at a bank in Raipur and at the Mahasamund Post Office.
He began appearing for the UPSC Civil Services Examination in 2022, dedicating himself entirely towards his goal, striking gold in the third attempt in 2025.
"I hope to serve the country through the civil services. Whether I secure an IAS cadre or another service, my commitment to public service remains firm," Dahariya said, crediting his success to the unwavering support of his family and mentors during his illness.
Mahasamund Collector Vinay Kumar Langeh and District Education Officer Vijay Kumar Lahare congratulated Dahariya, hailing his achievement, which serves as an example for courage and perseverance.
