Outline of Final Research Achievements

In this research, we aimed to develop a technique for the risk assessment of metals. Historically, the ecological risk assessment of metals was carried out based on the total concentration of metals in environmental medium. Recent researches revealed that the total metal is less responsible for the risk of metals on living organisms, but some forms of metals which are called bioavailable forms of metals are, and hence the risk assessments are carried out based on the bioavailability in the united states and European countries. Because soil and water quality are different in Japan, the direct application of the methodologies developed in other countries are difficult; hence, we aim to customize the methodologies to be applicable to Japanese cases.
