PM2.5 are tiny particles that can penetrate deep into the lungs and bloodstream. Once in the bloodstream, PM2.5 can travel to all parts of the body, including the pancreas, where insulin is produced. A study published in the British Medical Journal in 2023 found that a 10μg/m3 difference in annual average PM2.5 was associated with a 9-36% higher risk of developing type 2 diabetes. This study was conducted in India, which has some of the highest levels of air pollution in the world. The link between type 2 diabetes and air pollution is caused due to the long-term exposure of PM2.5.
