Investigation of Years of Life Lost Caused by Dust Storm in Western Part of Iran

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