Air Pollution May Cause Heart Disease; Nano-Sized Particles Most Damaging (Newswise) A new academic study led by UCLA revealed that the smallest particles from vehicle emissions may be the most damaging components of air pollution in triggering plaque build-up in the arteries that can lead to heart attack and stroke. The scientists also identified a way in which pollutant particles may promote hardening of the arteries - by inactivating the protective qualities of HDL ... [News Source]
