Abstract :
We aimed to assess health-impacts of short-term exposure to the air pollutants including PM10, SO2, and NO2 in
Shiraz, Iran in a two-part study from 2008 to 2010. In part I, local relative risks (RRs) and baseline incidences (BIs)
were calculate using generalized additive models. In part II, we estimated the number of excess hospitalizations
(NEHs) due to cardiovascular diseases (CDs), respiratory diseases (RDs), respiratory diseases in elderly group
(RDsE—people older than 65 years old), and chronic obstructive pulmonary diseases (COPDs) as a result of
exposure to air pollutants using AirQ model, which is proposed approach for air pollution health impact assessment
by World Health Organization. In part I, exposure to increase in daily mean concentration of PM10 was associated
with hospitalizations due to RDs with a RR of 1.0049 [95% confidence interval (CI), 1.0004 to 1.0110]. In addition,
exposure to increase in daily mean concentration of SO2 and NO2 were associated with hospitalizations due to
RDsE and COPDs with RRs of 1.0540 [95% CI, 1.0050 to 1.1200], 1.0950 [95% CI, 1.0700 to 1.1100], 1.0280 [95% CI,
1.0110 to 1.0450] and 1.0360 [95% CI, 1.0210 to 1.0510] per 10 ?g/m3 rise of these pollutants, respectively. In part II,
the maximum NEHs due to CDs because of exposure to PM10 were in 2009—1489 excess cases (ECs). The
maximum NEHs due to RDs because of exposure to PM10 were in 2009—1163 ECs. Meanwhile, the maximum NEHs
due to RDsE and COPDs because of exposure to SO2 were in 2008, which are 520 and 900 ECs, respectively. In
conclusion, elevated morbidity risks were found from acute exposure to air pollutants.
