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.

Hyderabad, Dec 22: Top Telugu actor Allu Arjun did not leave the theatre during the screening of 'Pushpa-2' on December 4 despite being told to do so in view of a stampede in which a woman died, police officials claimed on on Sunday.
Speaking at a press conference on the annual round-up of 2024, city police commissioner C V Anand showed a video, made by police, on the situation that prevailed when the stampede occurred.
The video was made by collating footage, including from news channels and cell phone clips. It suggests the actor remained in the theatre till the midnight.
Anand did not make any comment on the video, but said the media can draw its own conclusions.
A police official talked about the sequence of events on the fateful night of December 4.
He said that he and other police officials informed a manager of Allu Arjun about the death of the woman and told him that the situation was out of control. He indicated that they were not allowed to meet the actor.
Allu Arjun's staff members told them that they would convey the matter to the actor but did not do so, he said.
The official said he later managed to reach the actor, told him about the woman's death and asked him to leave the theatre so that the fans don't harm each other while trying to catch a glimpse of him.
The official also told the actor that security arrangements would be made for his exit.
However, the actor said he would go only after watching the film, the police official said.
Later, accompanied by a senior officer, the official went inside and brought the actor out, he said.
Amid allegations that bouncers hired by Allu Arjun pushed crowds as well as policemen when the stampede occurred at the cinema hall, the police commissioner warned that stringent action as per law would be taken if THE bouncers indeed misbehaved with the police on duty.
The VIPs would be made responsible for the behaviour of the bouncers hired by them, he said.
Asked if the police would appeal against the interim bail granted to Allu Arjun, the commissioner refused to give a direct response, just saying it is part of the investigation.
What course of action is taken would be known in the days to come, he said.
He also declined to comment when asked if the family of the deceased told him about Allu Arjun's team or film production team allegedly threatening them not to speak on the issue.
Meanwhile, state Cinematography Minister Komatireddy Venkat Reddy found fault with Allu Arjun responding on Saturday to the debate in the Legislative Assembly.
The minister, who observed that the actor should have respect for the government and the chief minister, demanded an apology from Allu Arjun to the government and the CM.
"This government is never vindictive. As Cinematography Minister, we allowed benefit shows and hiking ticket prices to promote the film industry," he said.
However, Union Minister of State for Home Bandi Sanjay Kumar found fault with CM Revanth Reddy for his comments on Allu Arjun in the Assembly on Saturday.
The comments of the CM sounded like character assassination of Allu Arjun and hurting the Telugu film industry, he alleged in a statement.
Later in the day, Sanjay Kumar visited a boy who is undergoing treatment in a hospital after being injured in the stampede.
"Consoled his father over the heartbreaking loss of his wife, Revathi. I pray to god that Sritej recovers at the earliest. Assured support to the family in this difficult time," Kumar said on X.
Earlier in the day, state DGP Jitender told reporters in Karimnagar district that film personalities and all others should understand that safety and security of citizens is utmost important, and also conduct themselves accordingly.
