| Research Abstract |
Geotechnical and geoenvironmental engineering has been contributed to the sound reuse/recycle of waste and by-products in Japan, since large amount of them not only from construction works but also from various industries and human activities has been widely utilized as geo-materials. However, the potential for soil and groundwater pollution due to toxic substances should be carefully assessed under the environment of each given application. This research have developed laboratory testing methods and their interpretation to simulate leaching and mobility of these toxic substances in the following situations ; 1) Long-term leaching behavior of hexavalent chromium from recycle concrete aggregate utilized as road base materials by employing acceleration tests, 2) Heavy metal mobility in coastal MSW incinerator ash landfill by developing modified batch leaching tests, and 3) Leaching characteristics of excavated soil containing arsenic by natural origin.
