POPULATION ATTRIBUTABLE FRACTION FOR HEALTH

초록

Growing body of evidence shows that possible unfavorable effect of particulate matters (PM) on health outcomes. Here, we estimate the population attributable fraction (PAF) for all-cause mortality, respiratory disease, cardiopulmonary disease, and lung cancer due to PM based on latest exposure data. For the exposure indicator, PM10 (smaller than 10µm in diameter) was used. It was measured 251 monitoring stations and presented in the Annual Report of Ambient Air Quality in Korea. Using regionally stratified PM10 data, the PAF was calculated as the World Health Organization (WHO) concept. The annual average outdoor PM10 concentration is 50 µg/m³ (range: 26-89 µg/m³). PAF was 2.7% for all-cause mortality, 5.7% for respiratory disease, 15.7% for cardiopulmonary disease, and 22.5% for lung cancer, respectively. It was approximately two times higher than 2004 WHO global burden of disease report. Although the concentration of PM10 has been decreased recently, it was still higher than WHO air quality guideline recommended maximum value of 20 µg/m³. Therefore, the efforts are needed to reduce burden of health problem caused environmental risk with air pollution reduction.
