Air pollution as bad as smoking a cigarette pack per day
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.

PM Modi speaks to Iranian president, discusses 'serious' situation in West Asia
New Delhi (PTI): Prime Minister Narendra Modi on Thursday night spoke to Iranian President Masoud Pezeshkian over the phone and discussed the "serious situation" in West Asia.
Modi expressed deep concern over the escalation of tensions in the region and the loss of civilian lives as well as damage to civilian infrastructure.
The prime minister told the Iranian President that the safety and security of Indian nationals, along with the need for unhindered transit of goods and energy, remain India's top priorities.
“Had a conversation with Iranian President, Dr Masoud Pezeshkian, to discuss the serious situation in the region. Expressed deep concern over the escalation of tensions and the loss of civilian lives as well as damage to civilian infrastructure,” Modi said in a post on X.
The prime minister also reiterated India's commitment to peace and stability and urged dialogue and diplomacy to end the crisis.
The prime minister had spoken to leaders of several West Asian countries in the last 10 days in the wake of the coordinated offensive launched against Iran by the United States and Israel, in which the Islamic country's Supreme Leader, Ali Khamenei, was killed last month.
In retaliation, Iran has fired drones and missiles at Israel and US military installations around the Gulf region, including the global business and aviation hubs of Dubai and Doha.
Modi earlier spoke to the leaders of Oman, Kuwait, Bahrain, Saudi Arabia, the UAE, Jordan, Israel and Qatar, and expressed concern over the attacks on their countries, and condemned the violation of some nation’s sovereignty and territorial integrity.
He also discussed the welfare and security of the Indian community residing in those countries.
Around 1 crore Indians live in the Gulf and West Asia. While about 10,000 Indian citizens live, study and work in Iran, more than 40,000 live in Israel.
