Long-term air pollution may quietly damage Indian kidneys, study reveals

A recent study involving over 12,000 Indians has found a significant link between long-term exposure to air pollution and kidney damage. The study, published in the journal Kidney International, indicates that even moderate levels of particulate matter (PM2.5) can lead to a decline in kidney function over time. This silent damage poses a serious public health threat, especially in India where air pollution levels are high. The findings underscore the urgent need for stricter air quality regulations and public health interventions to mitigate the adverse effects of pollution on kidney health and overall well-being.
