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.

Bhatkal: The Karnataka unit of the All India Ideal Teachers Association (AIITA) has welcomed the Karnataka government’s decision to strictly ban school children from dancing to obscene songs during educational and cultural programmes in government, aided, and private schools across the state.

AIITA Karnataka State President M. R. Manvi congratulated the government for taking what he termed an important step to preserve the sanctity of education.

“Such decisions to safeguard the dignity of school children and uphold the values of education are the need of the hour. This rule should not be limited to government schools alone but must be strictly implemented in all private educational institutions as well,” he said.

He further urged the government to address other concerns within school programmes.

“The government should not only prohibit obscene dances in the name of school anniversaries, but also ensure that plays and dialogues that incite religious hatred are avoided. Schools should be centres of harmony, not platforms for spreading hatred,” he added.

According to a recent circular issued by the Department of School Education and Literacy, obscene dances are adversely affecting the mental health and moral values of students.

In this regard, schools have been advised to use songs that promote nationalism, positive thinking, the greatness of Kannada culture, and value-based traditions instead of inappropriate content during programmes.
The circular also emphasises that students should be dressed in decent attire.

AIITA also backed the department’s warning that disciplinary action would be taken against head teachers if such guidelines are violated. The association has further demanded that district Deputy Directors of Public Instruction strictly monitor the implementation of these rules.
