A new study by IIT Bombay, published in Nature’s Clean Air journal, reveals alarming levels of cancer-causing pollutants in the Kamshet tunnel along the Pune-Mumbai Expressway. The research found that older diesel vehicles—making up just 21% of the traffic—are responsible for the majority of emissions, dominated by heavy polycyclic aromatic hydrocarbons (PAHs). These not only raise cancer risk but also significantly contribute to atmospheric warming due to their strong light-absorbing properties. The study highlights an urgent need for cleaner fuels and stricter emission controls.
