Abstract

Recently, the number of lead contaminated site is increasing in Japan, and the countermeasure costs of contaminated soil are burden to landowner . Now, the human health risk by direct ingestion of the lead contaminated soil is judged by which lead content in soil exceed soil content standard for lead (SCSL) (150mg/kg) or not . SCSL which established by Soil Contamination Countermeasures Law is a uniformly value regardless of land use. But the amount of lead ingestion via contaminated soil varies with land use, so human health risk varies with land use, too. In this research, the problem of way to set up SCSL is arranged, and the management target values (MTV) for several land use are computed by the detailed risk assessment and the countermeasure cost reduction rate by application of MTV is evaluated . Consequently, the maximum MTV is 5, 100mg/kg by an industrial use which is 34 times as SCSL. The cost reduction rate measured by MTV is 96% by an industrial use . In conclusion, it is possible that the greater part of countermeasure costs cut down byintroducing MTV, if land use industrial purpose. However, we need to be careful that we ignored the groundwater drinking pathway in the risk assessment.
