국내 일부 산단 지역 거주 주민의 중금속 농도 및 건강 영향에 관한 연구

This study conducted a survey on environmental awareness and analyzed outdoor PM10 and heavy metals (cadmium, lead) for 60 local residents living in the Gwangyang national industrial complex from July 2019. 40.0% of subjects responded that local environmental pollution was serious. Especially, there was a high proportion of residents living near the industrial complex or roads where it was perceived that local environmental pollution was serious. The average concentration of PM10 in the outdoors of the houses was 10.95 μg/m3 and the average concentration of heavy metals in PM10 was 1.90 ng/m3 for Cd and 24.92 ng/m3 for Pb. Overall, the average concentration of PM10 and heavy metals revealed a tendency to be high in the houses located near the industrial complex or the roads. As a result of a risk assessment carried out, the cancer risk of Cd was estimated to exceed 106 in the CTE, RME and Monte Carlo analysis. These results suggest that the urgent implementation of specific environmental health education for local residents is necessary.
