폐기물 처리장 분진에 의한 일개 비행단 관사 주민들의 건강 영향 평가

초록

Background : This study was conducted to reveal the health effects of air pollution on the residents living near waste treatment plant. Methods : We sampled 190 residents as the high exposed group, 192 residents as the moderate group, and 139 residents as the low exposed group according to the geographical distances from the waste treatment plant. Self-administered questionnaires for prevalence of respiratory disease, irritation symptoms of mucous membrane (eye, nose, th oat, skin, and respiratory tract), gastrointestinal symptoms, other nonspecific symptoms were conducted. We measured the concentrations of total suspended particles, Zn, Cu, Cr, Ni, Pb, Cd and As in 3 exposed area. Result : Airborne concentrations of total suspended particles measured in exposed area were 485, 365, and 332 μg/m³ which exceed the limit value. Airborne concentration of Zn, Cu, Cr, Ni, Pb, Cd, and As were not exceed the limit value. The prevalence of respiratory disease of high exposed group (16.8%) was significantly higher than that of moderate group (3.6%) and low exposed group (5.0%). The symptom score of irritation symptoms of mucous membrane, gastrointestinal symptoms, and other nonspecific symptoms were increased with exposed level. In multiple linear regression, exposure level was related to all symptom scores significantly. Conclusion : These results suggest that the air pollution of waste treatment plant would influence prevalence of respiratory disease, induce irritation of mucous membrane, gastrointestinal symptoms, and other nonspecific symptoms.
