산업단지 주변지역 실내공기의 PM10 중 중금속 노출 및 건강영향평가

Abstract

In this study, 40 residents of the Gwangyang and Yeosu areas were assessed for their level of exposure to heavymetals (As, Cd, Ni) from April 2017 to June 2018. The aim was to understand the differences in levels of indoorexposure to heavy metals (As, Cd, Ni), and a health risk assessment was conducted to determine whether therewas any fatal cause from carcinogenic elements. The mean concentrations of PM10 particles indoors were As 0.24μg/m3, Cd 0.07 μg/m3, and Ni 0.89 μg/m3. The health risk assessment for the arsenic, cadmium, and nickel inindoor air confirmed that the mean values exceeded the cancer risk tolerances specified by the U.S. EPA, for As(males 3.07 × 10−4, females 3.35 × 10−4), Cd (males 3.83 × 10−5, females 4.18 × 10−5), and Ni (males 6.36 × 10−5,females 6.95 × 10−5).
