In the study it was investigated the diffusion characteristics of heavy metal pollutions such as Cu, Pb, Hg and As which was the main pollution sources of soils from abandoned mines. The pollution of Cu and Pb was caused by Mine A, that of Hg was caused by Mine 3, that of Pb was caused by Mine C and that of Cu, Pb, As was caused by Mine D. Though the high concentration was detected within 100m from abandoned mines, the low concentration was detected over than 100m from abandoned mines in all heavy metals investigated except As. It means that it was very difficult to estimate the pollution level of As caused abandoned mines. The results were discussed in the concentrations of Cu, Pb and distances showed a good relationship with 0.71 and 0.68 as the coefficient of correlation, respectively. In particular the relativity of Cu to Pb as very strong with 0.84 as the coefficient of correlation. It was consistent with the chemical behavior in soils in the case of Cu and Pb. Therefore it will be a promising approach to remove Cu and Pb with estimated values in the study.
