Research Abstract

Marine sediments containing sulfide minerals (Fe2S) change to acidic soil gradually with a long-term atmospheric weathering and then various harmful heavy metals such as lead, cadmium and arsenic leach into environment. In this study, leaching characteristics of heavy metals from weathered marine sediments was investigated and low-cost environment-friendly immobilization technique of heavy metals with natural material was developed. By the application of this technique, leachabilities of various heavy metals from marine sediments decreased greatly. From the results of long-term stability test, heavy metals were immobilized in the marine sediment for a long time without anthropogenic impacts.
