Abstract :
The aims of the present study were to provide quantitative data on the impact of air pollution on the health of
people living in Tehran city, the most populated city of Iran. The approach proposed by the World Health
Organization (WHO) was applied using the AirQ 2.2.3 software developed by the WHO European Centre for
Environment and Health, Bilthoven Division. Concentrations of ozone, nitrogen dioxide, sulfur dioxide and
particulate matter of aerodynamic diameter ? 10 ?m (PM10) were used to assess human exposure and health
impacts in terms of attributable proportion of the health outcome, annual number of excess cases of mortality for
all causes, and cardiovascular and respiratory diseases. The annual average of PM10, SO2, NO2 and O3 in Tehran
were 90.58, 89.16, 85 and 68.82 ?g/m3, respectively. Considering short-term effects, PM10 had the highest health
impact on the 8,700,000 inhabitants of Tehran city, causing an excess of total mortality of 2194 out of 47284 in a
year. Sulfur dioxide, nitrogen dioxide and ozone caused about, respectively, 1458, 1050 and 819 excess cases of
total mortality. Results indicate that the magnitude of the health impact estimated for the city of Tehran
underscores the need for urgent action to reduce the health burden of air pollution.
