Top 10 Major Causes of Air Pollution in India & How to Control Them (2025 Update)

The top causes of air pollution in India include vehicular emissions, industrial waste, stubble burning, dust from construction, and household fuel use. Other major contributors are power plants, waste burning, and limited green cover. These factors severely affect air quality, leading to smog and rising health issues. To control pollution, India must promote clean energy, electric vehicles, afforestation, waste management, and sustainable farming practices. With collective action and stricter environmental policies, the nation can significantly reduce AQI levels and breathe cleaner air in 2025.

Air Pollution Triggers Genetic Mutations Leading to Lung Cancer, Major Study Finds

Source: www.jagran.com

A new international study published in Nature has unveiled a direct link between air pollution and lung cancer by showing that fine particulate matter (PM2.5) in polluted air can cause specific DNA mutations that trigger cancer. The research, led by scientists at the Francis Crick Institute and University College London, examined over 33,000 cancer samples from patients across multiple continents. The team identified a clear mutational signature—called SBS16—associated with air pollution, highlighting a previously underestimated genetic impact of airborne pollutants.

This research represents a significant shift in understanding how cancer can develop. While air pollution and lung cancer have long been linked to higher cancer rates, this study is among the first to show how PM2.5 particles can directly cause mutations, rather than just inflaming tissues or promoting existing cancer cells. “This mutational signature was found in cancer types not typically linked to smoking, especially in lung adenocarcinomas, indicating an alternative carcinogenic pathway,” noted Dr. Serena Nik-Zainal, a senior co-author.

Study Suggests Air Pollution May Be as Dangerous as Smoking in Some Cases

According to The Guardian, the scientists discovered that people living in polluted urban areas were more likely to develop lung cancers with this distinct mutation profile, even if they had never smoked. This upends traditional notions that most lung cancer cases in non-smokers were genetic or random. In particular, PM2.5 particles—smaller than 2.5 microns—were found to penetrate deep into the lungs and lodge in tissues, where they could cause these SBS16 mutations over time. This finding strengthens the direct connection between air pollution and lung cancer risk in non-smokers.

“These findings raise urgent public health concerns,” said Professor Charles Swanton, one of the lead researchers. “We now have biological evidence linking specific pollutants to mutations that drive cancer. This challenges the misconception that if you don’t smoke, you’re safe from lung cancer.”

In addition to lung cancer, similar mutational patterns were detected in other cancers, including those of the bladder and mouth, suggesting that airborne pollutants may have systemic impacts beyond the lungs.

Public Health and Environmental Implications

Environmental advocates and public health experts say this study may have major implications for air quality regulations and urban planning. Inside Climate News emphasized that this adds to a growing body of evidence calling for more aggressive global action to reduce PM2.5 emissions, especially in rapidly urbanizing countries.

Meanwhile, The Hill reported that researchers are also exploring potential protective measures, including the use of herbal remedies and antioxidant supplements. However, scientists caution that such interventions should not replace systemic environmental reforms. “No supplement can counteract decades of exposure to toxic air,” said Dr. Nik-Zainal, underscoring the need for preventive strategies over reactive ones.

In light of these findings, experts urge governments to update air quality thresholds and invest in clean energy solutions. With air pollution and lung cancer now proven to mutate human DNA, the call for climate justice and environmental health protections has never been louder.

Choking on Toxic Air: Pakistan’s Battle Against Lethal Pollution

Shaukat Korai

Karachi and Lahore, densely populated cities, have gained notoriety due to their severe air pollution crisis. Recent reports indicate that both cities are among the worst affected by air pollution, resulting in various health issues and a significant reduction in the average life expectancy of their residents by approximately 3-4 years. Former General Secretary of the Pakistan Medical Association (PMA), Dr Qaiser Sajjad highlights the hidden dangers of air pollution, describing it as a slow poison for human beings. “Despite being invisible, polluted air poses a grave threat to our health. Inhaling contaminated air can result in respiratory conditions such as bronchitis and laryngitis, causing inflammation of the throat, vocal damage, and breathing difficulties.” Furthermore, air pollution is closely associated with serious illnesses like lung cancer and bronchial carcinoma. It also contributes to the development of other ailments, including pharyngitis, sinusitis, and bronchial asthma. The harmful impacts of air pollution extend beyond the respiratory system, affecting the skin, eyes, and in severe cases, leading to fatalities. Director of Climate Action, Muhammad Yaser emphasizes the dire consequences of polluted air quality, which significantly reduces the average lifespan of citizens. Karachi experiences a decrease of 3 years in life expectancy, while Lahore suffers a staggering decrease of 7 ½ years and Islamabad faces a decrease of 4 years. When we breathe in polluted air, tiny particles enter our bloodstream, affecting every organ in our body. Our skin, eardrums, throat, and eyes, which act as the first line of defense, also suffer from the adverse effects, resulting in the development of various diseases. Yaser further explains that transportation is the primary contributor to pollution in Karachi, with 60 percent of emissions originating from this sector.
