An in-depth look at the most promising techlogy for metal remediation. With current cleanup methodologies offering real solution to the serious environmental implications of toxic metal contamination, there is a growing need among remediation professionals for effective, affordable, npolluting alternatives to energy-intensive engineering processes. This book presents one such promising alternative-the extraordinary new techlogy of phytoremediation. Through first-rate contributions from the top scientists in the field, Phytoremediation of Toxic Metals surveys worldwide pioneering efforts in the use of plants to treat contamination of such metals as lead, cadmium, chromium, and even radionuclides. The authors explore all major aspects of the techlogy-how it utilizes the metal-accumulating properties of selected or engineered plants to remove toxic metals from soils and water, how to transfer kwledge from the laboratory to the field, and what methods are most viable for commercial application. Complete, state-of-the-art coverage includes: The ecomic advantages of plant-based techlogy Regulatory considerations for future phytoremediation Phytoextraction, phytostabilization, and phytofiltration of toxic metals Photostabilization of metals using hybrid poplar trees Phytovolatilization for the special case of mercury and selenium The biological mechanisms of metal-accumulating plants
