Ischemic Heart Disease Events Triggered by Short-Term Exposure to Fine Particulate Air Pollution

This article published in Circulation 2006 shows a straight line correlation between PM 2.5 particulate air pollution and heart attacks and strokes on the same day. Whenever pm2.5 increases by10ug/m3, there are 4.5% more heart attacks and strokes on that day. With bad air day of pm2.5 at 75, one could expect 25% more heart attacks and strokes on that day.
