Nanotechnology-supported phytoremediation is a new approach in remediation of toxic metal polluted soils, but very little is known about the effects of nanoparticles on plant survival and performance in Pb-contaminated soil. Seedlings of K. scoparia were exposed to different regimes of nanoparticles of zero-valent iron (nZVI) to investigate nZVI effects on plant growth, Pb uptake and accumulation and physiological response. Results indicated that the total Pb contents in K. scoparia treated with low to moderate concentrations of nZVI (100-500 mg/kg) were higher than those in control, with the highest Pb accumulation capacity of 857.18 μg per pot obtained in soil treated with 500 mg/kg nZVI. Translocation of Pb from the roots to the shoots of K. scoparia slightly increased with nZVI content of soil from 100 to 500 mg/kg, while Pb transfer in K. scoparia was suppressed at higher nZVI doses. This might be related to the biomass reduction and decrease of chlorophyll content induced by high nZVI levels. Results provide a promising method to remediate Pb-polluted soil by applying proper amounts of nZVI to enhance phytoremediation performance. Selective interaction of plants and nZVI has great application prospects in the context of soil remediation.

Zero Valent Iron Nanoparticles

Zero-valent iron has been reported as a successful remediation agent for environmental issues, being extensively used in soil and groundwater remediation. The use of zero-valent nanoparticles have been arisen as a highly effective method due to the high specific surface area of zero-valent nanoparticles. Then, the development of nanosized materials in general, and the improvement of the properties of the nano-iron in particular, has facilitated their application in remediation technologies. As the result, highly efficient and versatile nanomaterials have been obtained. Among the possible nanoparticle systems, the reactivity and availability of zero-valent iron nanoparticles (NZVI) have achieved very interesting and promising results make them particularly attractive for the remediation of subsurface contaminants. In fact, a large number of laboratory and pilot studies have reported the high effectiveness of these NZVI-based technologies for the remediation of groundwater and contaminated soils. Although the results are often based on a limited contaminant target, there is a large gap between the amount of contaminants tested with NZVI at the laboratory level and those remediated at the pilot and field level. In this review, the main zero-valent iron nanoparticles and their remediation capacity are summarized, in addition to the pilot and land scale studies reported until date for each kind of nanomaterials.
