Rainbow pink, Vetiver grass, and Indian mustard were used in this study to test the remediation of the Cd, Zn, and Pb-contaminated soil. The objectives of this study are to assess the effect of applying EDTA on the phytoremediation of metals-contaminated soils and to assess the interactions among three metals in multiple metals-contaminated soils. Different applying methods with same amounts of EDTA are also used in this study to assess their effect on the metal concentration in the shoot of plant and on reducing the potential risk of groundwater contamination.

本研究於受镉、锌及铅污染的坋质黏土土壤中种植五彩石竹、培地茅及印度芥菜，利用此三种植物植生复育受多种重金属污染的土壤，污染土壤的镉、锌及铅浓度分别为20、500及1，000 mg/kg，评估施用EDTA对於促进植生复育的效果，并以镉、锌及铅浓度分别为10、100及1，000 mg/kg分别配制不同重金属污染土壤，研究三种重金属间交互作用对於植物累积重金属的影响，并评估以相同的EDTA施加总量分一至四次施用对植物累积重金属及降低地下水污染的风险的效果。
