Abstract

Phytoattenuation is a novel green remediation approach which can be employed in both sediment and a soil decontamination. Pot experiments have been conducted to evaluation two pollution levels of a sediments consisted of high pollution from swine industries and low contamination from campus wetland. EDTA demonstrated satisfactory metal uptake and mobility enhancement has been achieved. Pb is less mobile which induced low vetiver translocation while Zn is the most mobile which possesses high bioavailability. Four sessions of planting and harvesting gradually decreasing Cu and Zn levels the constrictions decreasing to achieve local a sediment criteria which can be used for agricultural a soil conditioning. The results of this study is prominent with gradually mitigating a sediment contamination is less detriment to a sediment properties relative to commonly used a soil washing.
