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