Abstract

An increased uptake of toxic metals by food crops grown on such soils together with human health risks are often recorded. Environmental pollution affects the quality of pedosphere, hydrosphere, atmosphere, lithosphere and biosphere. Great efforts have been made in the last two decades to reduce pollution sources and remedy the polluted soil and water resources. Phytoremediation, being more cost-effective and fewer side effects than physical and chemical approaches, has gained increasing popularity in both academic and practical circles. More than 400 plant species have been identified to have potential for soil and water remediation (Lone et al., 2008). This paper will provide a brief idea on recent progresses in research and practical applications of phytoremediation for soil and water resources.
