بررسی ارتباط میان آلودگی هوای آزاد و مرگ در اثر بیماری‌های تنفسی در کرمان، 1389- 1385

Background & Objectives: The effects of air pollutants on respiratory mortality and morbidity are among the major concerns today. Few studies have been published on the association between mortality and air pollution in Iran. Methods: This study was undertaken in Kerman, Iran. Mortality data was inquired from the Kerman City Health Authority (from March 2006 till Sept 2010) and air pollution data was requested from the Kerman Province Environmental Protection Agency (EPA). The Kerman Province EPA collects daily data on 7 air pollutants which are SO2, NO2, NO, NOx, PM10, CO and O3 by its urban measurement station. Results: The relation between respiratory disease mortality and air pollution was determined by negative binomial regression. The daily mean of PM10 in Kerman was above 150 μgr/m³(unhealthy) on some days of the year. The results showed a significant relationship between increased male respiratory mortality and increase in ambient dust (p=0.03), O3 (p=0.004) and SO2 (p=0.03), but did not show a significant increase in female mortality death for any pollutant. Conclusion: As there seems to be a significant relationship between increased ambient dust, O3, SO2 and respiratory mortality, susceptible people and those with background respiratory diseases should practice caution in case of increases in these air pollutants.
