Research Progresses in Soil Phytoremediation Polluted by Cadmium

Phytoremediation is the use of plants for the removal of pollutants from contaminated soil. Phytoremediation is an environmentally friendly and cost effective alternative to current remediation technologies. This review outlines general aspects of phytoremediation. It further reviews various phytoremediation processes in detail: phytoextraction, rhizofiltration, phytostabilization, rhizosphere degradation, and phytovolatilization. The hyperaccumulators of cadium and advances in the phytoextraction, phytostabilization, transgenic plants, agricultural technologies for soil phytoremediation by cadium were reviewed.
