BACKGROUND: Air pollution is an important environmental issue due to its proven serious impactson human health. The aim of this study was to estimate the attribution of particulate matter with anaerodynamic diameters of ≤ 2.5 and 10 (PM2.5 and PM10) in the prevalence of cardiovascular andrespiratory diseases and premature deaths in Isfahan in 2013–2014.MATERIALS AND METHODS: This descriptive, ecological study was conducted to assess healthimpacts of PM2.5 and PM10 on the population using Air Q2.2.3 software, suggested by the World HealthOrganization (WHO).RESULTS: The results showed that the annual mean, winter mean, summer mean, and the98 percentile of PM10 concentration in Isfahan were 108, 100, 116, and 264 µg/m3, respectively. Thenumber of deaths per year related to PM2.5 was 670 and that for PM10 was 713 cases. The numberof annual deaths due to cardiovascular and respiratory diseases attributed to PM10 was 316 and68 cases, respectively.CONCLUSION: The results of this study revealed that about 44.3% of total annual death due tocardiovascular diseases and 9.55% of that due to respiratory diseases were attributed to PM10exposure. In the other word, residents were exposed to PM2.5 and PM10 concentrations higher thanthe WHO guidelines which caused a notable increase in the rate of mortality.
