New York, Aug 14: Researchers have found that ozone air pollution which is increasing with climate change can accelerate lung disease as much as that by smoking a pack of cigarettes a day.
"We were surprised to see how strong air pollution''s impact was on the progression of emphysema on lung scans, in the same league as the effects of cigarette smoking, which is by far the best-known cause of emphysema," said Joel Kaufman, Professor at the University of Washington.
If you live in areas with increased levels of ozone, researchers found an increase in emphysema roughly the equivalent of smoking a pack of cigarettes a day for 29 years.
The study, published in the journal JAMA, demonstrates an association between long-term exposure to major air pollutants - especially ozone - with an increase in emphysema seen on lung scans.
Emphysema is a condition in which destruction of lung tissue leads to wheezing, coughing and shortness of breath and increases the risk of death.
The results are based on an extensive, 18-year study involving more than 7,000 people and a detailed examination of the air pollution they encountered between 2000 and 2018 in six metropolitan regions across the US. The participants were drawn from the Multi-Ethnic Study of Atherosclerosis (MESA) Air and Lung studies.
"To our knowledge, this is the first longitudinal study to assess the association between long-term exposure to air pollutants and progression of percent emphysema in a large, community-based, multi-ethnic cohort," said Meng Wang, Assistant Professor at the University at Buffalo.
While most of the airborne pollutants are in decline because of successful efforts to reduce them, ozone has been increasing, researchers said. Ground-level ozone is mostly produced when ultraviolet light reacts with pollutants from fossil fuels.

Bengaluru, Aug 19: Former Karnataka Chief Minister H D Kumaraswamy on Monday said he was not afraid of any probe into the phone tapping allegations, as he accused the BJP government of running a "transfer business" in the State.
The JDS leader's statement triggered a war of words with chief minister B Yeddiyurappa's son B Y Vijayendra saying it was not appropriate to make "baseless allegations."
Yediyurappa, however, said he was not going to react to the charges.
"Why do you want to put words in my mouth? May God bless him. The whole world knows what he has done..," he told reporters.
It all started with Kumaraswamy's purported statement on Sunday that Yediyurappa had left his sons to run the 'transfer businesses' as reported by some news channels.
Taking a serious note of it, Vijayendra tweeted the clipping of Kumaraswamy's statement as it appeared in a Kannada news channel, which read that Yediyurappa has "let his son loose to run the transfer business."
"...You cannot pass the buck on somebody else for your deeds. Stop trying to mislead the people through falsehood just because you are scared of the CBI probe into the telephone tapping case," he said.
Vijayendra also tweeted links to news reports that claimed the then PWD minister H D Revanna had transferred 700 officials on a single day last year when Kumaraswamy was the chief minister.
Later, speaking to reporters in Bengaluru, Vijayendra slammed Kumaraswamy for making "baseless allegations" against him and his family.
"It is not appropriate to make baseless allegations against me and our family. It does not befit his stature," Vijayendra said.
He challenged Kumaraswamy to make the facts public if he has evidence to back his claim.
"People have seen how during your tenure governance had collapsed due to the involvement of your family. People of the state have seen how 700 staff in the PWD were given promotion and transferred," Vijayendra said.
Reacting, Kumarasawmy cautioned chief minister Yediyurappa to keep his children "within their limits."
He alleged that the chief ministers residence has turned into a "transfer market" these days.
Speaking about the governments intention to conduct a CBI probe into the alleged phone tapping, Kumaraswamy said he was not scared of any probe because he did not do anything wrong.
However, he asked the chief minister not to fix innocent people only to take revenge on him.
Days after phone tapping allegations during the previous Congress-JDS coalition government surfaced, Yediyurappa on Sunday said he will order a CBI probe citing demands by several political leaders including from the Congress.
