Study Links Long-Term PM2.5 Exposure to Millions of Global Cancer Cases
A global study published in Nature Health linked long-term exposure to fine particulate matter (PM2.5) to 8.82 million cancer cases worldwide between 2000 and 2020. PM2.5 was identified as the leading air pollutant contributing to cancers not only of the respiratory system but also the reproductive and endocrine systems. The research found a 16% increased cancer risk per 10 micrograms per cubic metre rise in PM2.5. The findings highlight concerns for countries like India, where PM2.5 levels remain persistently high, contributing significantly to cancer incidence.
