Health effects of air pollution have increased recently and there are a lot of concerns. Troposphere ozone is a pollutant that mainly enters the body through the respiration. This gas cause respiratory complications (reduced lung capacity, asthma, and nasal congestion), eye burning sensation, and failure of immune defense against infectious diseases. This study was conducted to examine the hygienic effects of ozone pollution in Tabriz since it is one of the polluted Iranian metropolises. Materials & Methods: Ozone data were taken from the Department of Environment Office of East Azerbaijan Province in Tabriz (TDOE). Conversion between volumetric and gravimetric units (correction of temperature and pressure), processing and filtering were implemented. The hygienic effects resulting from exposure to ozone gas (such as mortality rates, Respiratory diseases, cardiovascular diseases and COPD) were estimated using Air Quality Model in Tabriz. Results: The results of this study showed that the relative risk (RR) attributed proportion (AP) and cumulative of total mortality made by the ozone were 350 persons respectively in Tabriz. O3 (1 hour average) and 98th percentile of ozone was 63.21 and 99.06 μg/m3 respectively. About 2.4% of the cardiovascular mortalities, 0.27% of respiratory mortalities and 0.3% of the patient's hospitalization suffering from the chronic pulmonary clogging have been attributed to more than 10 micrograms per cubic meter of the ozone concentrations in Tabriz. Conclusion: This study showed for 10 μg/m3 increase in ozone concentration, the risk of mortality increased about 0.45%. Also the results of other studies showed ozone pollution in metropolitan of Tabriz is approximately equal with Tehran. Therefore, air pollution in Tabriz must be considered as a serious problem and requires the attention of the decision makers for the control of it. The higher ozone pollutant value can depict mismanagement in urban air quality.
