Weather is one of the essential needs of human. Due to increasing of the air pollution, air pollution is one of the most important challenges of human life, in the last decades. Air pollutants, including NO2 can have significant adverse health effects on the human. Therefore, evaluation of the health effects of this pollutant is necessary for its control. The aim of this study was evaluation of health effects of NO2 on the human in Mashhad, Tabriz, Shiraz, Isfahan and Arak metropolises of Iran in 2011-2012. Materials and methods: The necessary data was obtained from Environmental Protection Agencies of related metropolises. The validity of data was evaluated according to the WHO criteria. The valid data entered into the AirQ software and the results were obtained. Results: Isfahan with the annual concentration of 128 μg/m3 has the highest concentration of NO2. In all cities, the average concentration was higher than the national standard. For total mortality, cardiovascular death and hospitalization for chronic obstructive pulmonary, Mashhad had the greatest number, with 286, 161 and 43 cases, respectively. Conclusion: the most adverse health effect of NO2 was in Mashhad and Isfahan cities, respectively.
