hospital admission for respiratory and cardiovascular diseases due to particulate matter in ilam, iran

Background: particulate matter with an aerodynamic diameter lower than 10 μm(pm10) has the most undesired adverse effects on human health. several studies reported a strong correlation betweenpmlevels and hospital admissions owing to chronic and acute respiratory and cardiovascular diseases. objectives: the current study aimed to estimate the effect of pm10 as a primary pollutant on respiratory and cardiovascular hospitalizations in ilam, iran, in 2013. methods: pm10 data was taken from the ilam environmental protection agency. the annual morbidity including hospital admission for respiratory and cardiovascular diseases due to pm10 exposure were estimated using relative risk (rr) and baseline incidence (bi) based on world health organization (who) databases for airq2.2.3 model. results: the results showed that the maximum level of pm10 was obtained in summer with a concentration of 491 g/m3. the cumulative number of excess cases admitted to the hospital for respiratory and cardiovascular diseases were 216 and 84, respectively. approximately 3.95% of the cases hospitalized due topm10 occurred during days with concentration levels lower than 20 μg/m^3. the highest rate of person-days related to pm10 that led to heath effect among ahvaz inhabitants was in concentration levels of 40 - 49 μg/m^3. conclusions: to reduce the impacts of particulate matter on health status of people in ilam, necessary training by health systems should be conducted for people, especially those with chronic lung and heart diseases, the elderly and children to reduce their activities on the dusty days.
