In this study, we analyzed the concentration of cadmium and mercury in urine and lead in blood from 668 residents in the exposed and compared areas in Gwangyang-si and Yeosu-si, from July 2013 to December 2015. According to the lifestyle (past smoking, current smoking, passive smoking, drinking and exercise), the concentration of cadmium in urine was higher in the compared areas than in the exposed areas in Gwangyang. However, the concentration of cadmium in urine according to the lifestyle except drinking was higher in the exposed areas than in the compared areas in Yeosu. According to the past smoking and current smoking, the concentration of mercury in urine was higher in the compared areas than in the exposed areas in Gwangyang, but the passive smoking, drinking and exercise showed similar concentration levels both in the exposed and compared areas in Gwangyang. The concentration of mercury in urine according to the past smoking and current smoking was higher in the exposed areas than in the compared areas in Yeosu, but the concentration of mercury in urine according to the drinking and exercise was lower in the exposed areas than in the compared areas in Yeosu. According to the past smoking, the concentration of lead in blood showed similar concentration levels in the exposed and compared areas in Gwangyang, but regarding current and passive smoking, it was higher in the compared areas than in the exposed areas in Gwangyang. Especially, the concentration of lead in blood according to the drinking in Gwangyang showed statistically significant difference (p<0.05). The concentration of lead in blood according to the lifestyle was higher in the compared areas than in the exposed areas in Yeosu.
