Experts reject Kirti Vardhan’s remark, say pollution, lung disease link is proven

New Delhi: The Union Environment for State Kirti Vardhan singh asserted that air pollution has no link to lung diseases, flies in the face of decades of settled medical science and global public health evidence, drawing sharp criticism from doctors, epidemiologists, and environmental experts.

From the World Health Organization (WHO) to The Lancet, from India’s own Indian Council of Medical Research (ICMR) to the Global Burden of Disease (GBD) study, the link between polluted air and lung disease is not speculative, it is conclusively established.

Actually the issue erupted, after the Minister made a state in parliament that there is no direct correlation between higher Air Quality Index (AQI) levels and lung diseases, with no ‘conclusive data’ to establish such a link, even as the government acknowledged that air pollution is one of the triggering factors for respiratory .

According to the WHO, air pollution is one of the leading causes of respiratory illnesses, including asthma, chronic obstructive pulmonary disease (COPD), lung cancer, bronchitis, and reduced lung development in children.

Fine particulate matter (PM2.5), which penetrates deep into the lungs and bloodstream, causes chronic inflammation, scarring of lung tissue, and long-term respiratory impairment.

India itself offers overwhelming evidence. Studies conducted by AIIMS and ICMR have consistently shown higher rates of asthma, reduced lung capacity, chronic cough, and respiratory infections in cities with elevated pollution levels.

Children growing up in highly polluted urban centres have been found to have permanently stunted lung growth, a damage that cannot be reversed later in life.

Globally, The Lancet Commission on Pollution and Health has repeatedly warned that air pollution is responsible for millions of premature deaths every year, with respiratory diseases forming a major share. In fact, air pollution is now considered a risk factor on par with smoking when it comes to lung damage.

Medical science explains this clearly, toxic pollutants such as nitrogen dioxide (NO₂), sulphur dioxide (SO₂), ozone, and PM2.5 irritate airways, weaken lung defence mechanisms, and make people more vulnerable to infections like pneumonia and tuberculosis. Long-term exposure does not just aggravate existing conditions — it creates disease in otherwise healthy individuals.

The minister’s statement is particularly alarming in a country like India, where some of the world’s most polluted cities are there. Experts warn that denying the pollution, lung disease link is not merely inaccurate , it is dangerous.

Such claims risk undermining urgent policy action, weakening enforcement of air quality standards, and misleading the public about real and present health threats.

Science does not bend to political convenience. The evidence is overwhelming, global, and unequivocal, dirty air damages lungs, causes disease, and kills. Any attempt to deny this reality stands isolated against the collective voice of modern medicine and public health research.
