Background & Aims of the Study: In this study, we evaluate the respiratory deaths which werecaused by exposure to PM10 in Ahwaz, Bushehr and Kermanshah cities of Iran during 2015 byAir model Q2.2.3.Materials and Methods: The required data gathered from the department of environment andmeteorological organization in three study areas. Data were analyzed, using Excel software at thenext stage with implementation of pressure and temperature correction, programming,processing (average) and filtering.Results: The results showed that approximately 17% of respiratory deaths in Kermanshah areattributed to over 30 μg/m3 concentration of PM10, 19% of respiratory deaths in Bushehr city areattributed to concentrations over 20 μg/m3 and 25% of respiratory deaths in Ahwaz are attributedto concentrations over 120 μg/m3. The higher percentage of death due to this implication mightbe because of higher average of PM10 or duration of days with high concentration in Ahwaz citywhich were caused by recent dosage of dust in this city compared to two other cities. Inaccordance with the comparison of total respiratory death which is attributed to PM10 at threestudy areas in 2015 indicated that Ahwaz had the most respiratory mortalities while Kermanshahhad the lowest one and the risk of respiratory deaths would increase by 1/2% with 10 μg/m3increase in PM10 concentration. The total lost years of life attributed to PM10 during last 10 yearshave been 348874 years, 43839 and 11660 in Ahwaz, Kermanshah and Bushehr, respectively.Conclusion: Results shown Ahwaz has the largest number of lost years of life and Kermanshahhad the fewest number of lost years of life.
