Also air pollution has adverse impacts on human health. The objective of this study is to compare of relative risk and attributable proportion exposure to Nitrogen dioxide in the southwest of Iran. Methods: This descriptive study was conducted in Ahwaz, Kermanshah and Bushehr cities during 2012. In this study, Data were collected from Department of Environment (DOE) and analyzed to determine the relative risk (RR) and attributable proportion (AP) of NO2 in three mentioned cities. Results: Based on the results, the total accumulative number of cardiovascular death attributed to exposure with NO2 in Ahwaz, Kermanshah and Bushehr were 43, 48 and 4 cases, respectively. The relative risk of NO2 attributed to cardiovascular death was in a moderate level (1.002). The maximum and minimum number of obstructive pulmonary disease attributed to NO2 was observed in Kermanshah and Bushehr with 21 and 3 cases, respectively. Conclusion: According to this study increasing the NO2 concentration has a direct and significant effect on death rates of cardiovascular and obstructive pulmonary diseases.
