Association of Health Effects of Air Pollution on Chronic Obstructive Pulmonary Disease (COPD)

Background & Aims of the Study: Lung is directly exposed to surrounding air and existingpollutants to perform its natural task. In this paper, COPD cases attributed to NO2, O3, and SO2were studied based on assessed data in Ahvaz city of Iran during 2014-2015.Materials and Methods: Data were processed by Excel through steps including temperatureand pressure correction, programming, processing (average) and filtering.Results: The results indicated that number of COPD cases was estimated to 15 members inaccordance with the central relative risk, so, each 10μg increase in NO2 concentration would leadto 0.38% increase in COPD risk. Each 10μg/m3 increase in Ozone concentration causes 0.58%increase in disease attributed to this pollutant. Number of cumulative cases of this disease hasbeen equal to 35 members during 2014-2015. Estimated cumulative number of obstructivepulmonary caused by sulfur dioxide has been estimated to 20 members during 2014-2015.Obviously, each 10μg/m3 increase in SO2 concentration would lead to 0.44% increase in risk ofthe considered disease.Conclusion: In conclusion, O3 as a pollutant has the most effect on COPD compared to the othertwo pollutants in Ahvaz city of Iran during 2014-2015. This might be because of more days withhigh concentration of this pollutant compared to other two pollutants in Ahvaz. If emission ofthis pollutant is not prevented, number of people who are suffering from COPD will increase to55 members in 2016 and it will be reduced to 13 members in case of control.
