Abstract

According to World Health Organization estimations, 3.7 million deaths were attributable to ambient air pollution annually, that shows pollutants associated with high rate of mortality and morbidity. Thus, present study with aim of quantifying and estimating health impacts attributable to two pollutant of PM2.5 and CO in 8 industrial cities of Iran during 2011 by AirQ model were performed. Methods: At first, required data were taken from Department of Environment in understudy cities. With coding in excel, analysis and calculation of statistical parameters was performed for quantifying, and information imported to AirQ model. Finally, results of total mortality and mortality due to cardiovascular disease were presented in tables and graphs. Results: According to results, with increasing each 10μg/m3 concentration of PM2.5 and 1mg/m3 increasing in CO, risk of mortality increased 1.5% and 0.7% respectively. Cumulative of total mortality attributable to PM2.5 in Isfahan and Shiraz was estimated 585 and 454 cases that this rate is allocated of 5.42% of all deaths in these cities. Sum of cumulative cases of mortality for CO in Isfahan, Tehran and Shiraz estimated 14 (2.15%), 24 (0.86 %) and 3 cases (0.69%) respectively. Conclusion: The study emphasized that PM2.5 and CO as well as other pollutants have adverse affect on human health. Among 8 under study cities, Ahwaz had lowest mortality attributable to CO and highest mortality attributable to PM2.5, which it can be due to either continuing of days with higher concentration of particulate or higher average of this pollutant in Ahwaz city.
