Air pollution’s tiny particles may trigger nonfatal heart attacks — ScienceDaily

Yale-affiliated scientist finds that even a few hours’ exposure to ambient ultrafine particles common in air pollution may potentially trigger a nonfatal heart attack. Myocardial infarction is a major form of cardiovascular disease worldwide. Ultrafine particles (UFP) are 100 nanometers or smaller in size. In urban areas, automobile emissions are the primary source of UFP. […]
