Scientists are just beginning to understand what exactly makes PM2.5 so harmful, but a major reason is that it’s so small and contains toxic metals. Its size allows it to penetrate the lungs and enter the bloodstream. There, it can circulate to different organs and cause inflammation. The inflammation increases insulin resistance. Eventually, this insulin resistance can become so severe the pancreas becomes unable to pump out enough insulin to compensate, and diabetes can set in.
Interesting anyway.
