Mining activities has generated large amounts of mine tailings each year, and these usually contain high concentrations heavy metal pollutants, which not only cause serious damage to the local surrounding soil ecosystems, but also harm human health via transmission food chain. Phytoremediation is treated as environmentally friendly, long-term effective low-cost restoration method. However, tail...

The technology of phytoremediation is cost effective and ecologically friendly in which plant utilizes its natural abilities to restore environment. In nature there are a number of plants existing with innate mechanisms for removing heavy metals from soil, air and water as a survival strategy.  Among several subsets of phytoremediation, the widely studied strategies are (a) phytoextraction (b) ...

Soil contamination by metals threatens both the environment and human health hence requires remedial actions. The conventional approach of removing polluted soils replacing them with clean (excavation) is very costly for low-value sites not feasible on a large scale. In this scenario, phytoremediation emerged as promising cost-effective environmentally-friendly technology to render less bioavai...

Due to extensive mining activities, strip vegetation and soil contamination with heavy metals have become common. One of the approaches ecological restoration is phytostabilization, which uses plants stabilize reduce mobility in soil. In this study, six species grasses – namely, Alloteropsis semialata (R.Br.) Hitchc., Cymbopogon citratus (DC.) Stapf, Dinochloa acutiflora (Munro) Soenarko, Imper...

Lygeum spartum is a native species in semiarid Mediterranean areas that grows spontaneously on acid mine tailings. We aimed to study the suitability of this plant for phytostabilization. L. spartum was grown from both seeds and rhizomes in acid mine tailings with various fertilizer and lime treatments. Untreated soils had a solution pH of 2.9 with high concentrations of dissolved salts (Electri...
