The Guardian has reported that after a seven-year study of 12,000 residents of Delhi a link has been found between PM2.5 particles and increased blood sugar levels
The study found that inhaling polluted air with high amounts of PM2.5 increases the risk of type 2 diabetes. When inhaled, PM2.5 particles – which are 30 times thinner than a strand of hair – can enter the bloodstream and cause several respiratory and cardiovascular diseases.
