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 (PTI): Targeting Chief Minister Siddaramaiah and the Congress government in Karnataka on corruption, BJP leader R Ashoka on Friday said, being foolish was forgivable, but being "shameless" in public life was not.

The Leader of Opposition in the state Assembly claimed that in just 30 months of its tenure, the Congress administration has broken every previous record on corruption-related controversies.

He was responding to Siddaramaiah's post on 'X' on Thursday hitting back at the BJP, stating that Upa Lokayukta Justice Veerappa's claims of "63 per cent corruption" were based on his report in November 2019, when BJP's B S Yediyurappa was the CM.

"But Ashoka, without understanding the Upa Lokayukta's statement properly, has ended up tying the BJP's own bells of sins onto our heads and has effectively shot himself in the foot," the CM had said, as he accused Ashoka of foolishness for trying to twist Veerappa's statement to target the current government.

Responding, Ashoka said, "it is one thing to be called foolish in politics, that can be forgiven."

"But in public life, especially in the Chief Minister's chair, one must never become shameless," Ashoka posted on 'X' on Friday addressing Siddaramaiah.

Noting that the CM himself had admitted on the floor of the Assembly that a Rs 87 crore scam took place in the Valmiki Development Corporation, he said that when a CM acknowledges such a massive irregularity inside the floor of the House, the natural expectation is immediate action and accountability.

"But instead of taking responsibility, you continue in office as if nothing has happened. What should the people of Karnataka call this, if not sheer shamelessness," he asked.

Pointing out that the CM's Economic Advisor and senior Congress MLA Basavaraja Rayareddy had publicly stated that under Congress rule, Karnataka has become No.1 in corruption, Ashoka said, "Yet, you still cling to the Chief Minister's chair without a moment of introspection. What should the people of Karnataka call this, if not sheer shamelessness."

Senior Congress MLA C R Patil had exposed the "money for House" racket in the Housing Department and even warned that the government would collapse if the details he has were made public, Ashoka said.

"Despite such serious allegations from within your own party (Congress), you neither initiated an inquiry nor acted against the concerned minister. What should the people of Karnataka call this, if not sheer shamelessness," Ashoka asked the CM.

Highlighting the "40 percent commission" allegation Congress made against the previous BJP government, the opposition leader said, the commission that the Siddaramaiah government appointed concluded that the accusation was baseless.

"After your own panel demolished your own claim, what moral right do you have to continue repeating that allegation. What should the people of Karnataka call this, if not sheer shamelessness," he asked.

For the last two and a half years, Karnataka has been 'drowning' in corruption, scandals, irregularities and allegations across departments. Ashoka said, "If I begin listing every case that emerged under your government, even 24 hours would not be enough." 

"And the most tragic aspect of your administration is this: the unbearable pressure, corruption demands and administrative harassment under your government pushed several officers and contractors into extreme distress - including the suicide of Chandrasekharan which exposed the Valmiki Development Corporation scam - a sign of how deeply broken the system has become under your watch," he said.

Instead of fixing this hopeless environment, the government has tried to bury every complaint and silence every voice, he charged.

"Being foolish is forgivable, but being shameless in public life is definitely not."

"When your own ministers admit scams, when your own advisors certify Karnataka as No.1 in corruption, and when your own MLAs expose rackets inside your departments - clinging to power without accountability is not leadership. It is shamelessness in its purest form." PTI KSU

Earlier on Thursday Ashoka had demanded that the corruption case and allegations in the state against the Congress government be handed over to a CBI investigation, citing a reported statement by Upalokaykta Justice Veerappa alleging "63 per cent corruption", following which Siddaramaiah hit back at the BJP leader.
