Remediation of Heavy Metals-Contaminated Soil (original) (raw)

Abstract

The currently used techniques for soil remediation such as landfilling or metal extraction using toxic agents as well as the use of metal-chelating bio-surfactant need to be replaced by green technology solution. Therefore, the research was designated to study the ability of plants to bio-accumulate, translocate and remove some metals such as copper, zinc, lead and cadmium from contaminated soil. The herbal plant ryegrass, Lolium multiflorum was investigated as a bio-accumulator plant for these metals. The translocation of these heavy metals in ryegrass was compared considering root to shoot transport and redistribution of metals in the root and shoot system. The trace metal contents from root and shoot parts were determined using atomic absorption spectrometer. The results showed that the percent of copper, zinc, lead and cadmium transferred to ryegrass plant were 96.01, 84.51, 51.39, and 74.57%, respectively, while those remained in the soil were 3.81, 14.42, 45.16 and 27.40 % fol...
