The results obtained were as follows. 1. The Contents of cadmium and Lead in water were in the range of 0~2.15$\mu$g/l, 0~4.29$\mu$g/l, respectively. 2. The Contents of heavy metals in soil were in the range of 0.32~0.91mg/kg, 5.59~21.55mg/kg for Cd, Pb respectively. 3. Those in rice were in the range of 0.025~0.062mg/kg for Cd, Pb respectively. 4. The mean of Lead and Cadmium Concentration in Urine of residents of Munju Ri were 28.63$\mu$g/l and 1.66$\mu$g/l respectively, Those was also the highest level among the investigated group.
