摘要：
Phytoremediation is the use of plants for the removal of pollutants from contaminated soil or water. Phytoremediation is an environmentally friendly and cost-effective alternative to current remediation technologies. This review article outlines general aspects of phytoremediation, along with discussions about its advantages and limitations. It further reviews various phytoremediation processes in detail: phytoextraction, rhizofiltration, phytostabilization, phytodegradation, and phytovolatilization. Unlike previous review articles available in various journals, this paper presents a more comprehensive view of this issue, and deals with a much wider range of its applications to environmental pollution control. These include the treatment of wastewaters, removal of heavy metals and metalloids (e.g. lead and arsenic), phytoremediation of organic pollutants, such as 2,4,6-trinitrotoluene (TNT) and polychlorinated biphenyls (PCBs), and cleanup of soil and water contaminated with radionuclides, such as cesium (137Cs) and strontium (90Sr). This paper also describes recent developments of transgenic plants for improving phytoremediation. Along the way, the present status of phytoremediation research in Korea is briefly introduced. Finally, the article concludes with suggestions for future research.
