 Today, air pollution is a major issue in the world, particularly in metropolitan areas.

 Accordingly, this study aimed to investigate the relationship between air pollution and mortality in the elderly in Kerman City.

 This ecological study was conducted using 2006 - 2013 mortality data inquired from the Deputy of Health of Kerman University of Medical Sciences. The data on cardiovascular and respiratory mortality, as well as death due to trauma, diabetes, and other diseases that happened in men and women aged 60 and higher were extracted. Air pollution data (CO, SO2, O3, NO, NO2, NOx, and PM10) for the same time frame were inquired from the Environmental Protection Agency of Kerman Province. Negative binomial regression was used to evaluate the relationship between air pollutants and mortality using STATA13 software.

 During the study period, a total of 14,793 deaths occurred in elderly men and women in Kerman City. Cardiovascular diseases were the leading cause of death. The results of multivariate analysis of air pollutants indicated that NO was directly and significantly related to a total number of deaths in the elderly, and an increase in sulfur dioxide and ozone; moreover, NO was significantly related to increased mortality among elderly women. Carbon monoxide was significantly related to cardiovascular death of the elderly. But air pollutants did not show any significant effect on respiratory-, trauma-, and diabetes-related deaths.

 Our findings indicate that there is a significant relationship between air pollution and mortality in the elderly. Accordingly, a warning system is suggested to reduce the elderly’s commuting on highly air polluted days.
 

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.
