| 講演要旨(和文) | | 初期段階における土壌汚染領域の絞込みを目的として、土壌の電気的性質に着目し、土壌電気伝導度(土壌EC)の測定や非抵抗法探査の現場調査への適用性について検討した。汚染の検討対象として重金属廃液の漏洩を想定し、土槽を用いた基礎的な実験を行った結果,表層汚染に対しては土壌ECの測定が有効であり、汚染物質が地中に浸透しているケースでは深度情報が得られる比抵抗法探査の適用が有効であることがわかった. |

| | 講演要旨(英文) | | To specify soil contamination zone in the early stage of investigation, we focused on an electrical properties of soil and examined applicability of the measurement electric conductivity of soil and the resistivity survey method to on-site survey.As an experimental target of pollution cases, leakage of the heavy metal waste fluid was selected, and basic experiment was done. As a result, it was clarified that the measurement electric conductivity of soil was effective to the surface pollution. Moreover, in case of the contaminant had infiltrated into the ground, it was proved that the application of the resistivity survey method was effective. |
