Current Summary of Percent Changes in Acute Mortality per 10 Units of Pollutant Talar Sahsuvaroglu, PhD, Senes 2012
Deaths from Air Pollution Each Year(Ontario Medical Association 2008) Toronto 2,100 Peel 700 Hamilton 186 - 440 Halton 330
Health Effects/MortalityExposure to PM2.5 over a few hours to weeks can trigger cardiovascular disease–related mortality and nonfatal events; Longer-term exposure (eg, a few years) increases the risk for cardiovascular mortality to an even greater extent Greater risk may include the elderly, patients with preexisting coronary artery disease, and perhaps those with diabetes. Recent data suggest that women and obese individuals might also be at higher risk. Brook et al, Circulation 2010, 121:2331-2378: 80% of mortality is in over 65 year old groupOntario Medical association 2008For every $ of govt funds to reduce air pollution exposures, approx $50 to $150 is saved in the health care system and productivityCorr Research 2012
