Evaluation of cardiovascular and respiratory mortality attributed to atmospheric SO2 and CO using AirQ model

In this study, the health effects of exposure to carbon monoxide (CO) and SO2 in the air of 6 Iranian metropolises in 2011-2012 were examined.

| Summary: | Background: Air pollutants have multiple adverse effects on human health. In this study, the health effects
of exposure to carbon monoxide (CO) and SO2 in the air of 6 Iranian metropolises in 2011-2012 were
examined.
Methods: Raw data was collected from the Iranian Department of Environment and the Iran Meteorological
Organization. After validation, the required statistical indices were calculated through programming and
modifying temperature and pressure in Excel software. The output of Excel was given to the AirQ model,
and the results were presented as the cases of death.
Results: The annual mean concentrations of SO2 were 2.45, 1.55, 0.6, 0.55, 1.05, and 3.8 times higher than
the guidelines of the World Health Organization (WHO) (20 μg/m3) in Tehran, Mashhad, Isfahan, Shiraz,
Tabriz, and Urmia, respectively. The concentrations of CO did not exceed the standard limit in any of the
studied cities. The cumulative numbers of total deaths attributed to SO2 were 744, 122, 132, 44, 37, and 107
in Tehran, Mashhad, Isfahan, Shiraz, Tabriz, and Urmia, respectively. The highest mortality rate was found
in Urmia at 2.9% followed by Tehran at 1.52%; the lowest rate of 0.46% was found in Tabriz.
Conclusion: The results show that of the 6 metropolises, the highest CO mortality rate of about 2.15%
belonged to Isfahan followed by Arak with about 1.38%, and the lowest rate of 0.68% belonged to Mashhad.
Because of the growing trend of air pollution and its mortality rate and adverse effects, practical solutions
for the control and reduction of air pollution in Iranian metropolises are necessary. |
