<p>Vetiver grass and it usages have been widely investigated in many researches as the preferred plant species due to its known efficiency, low cost, the ease of availability and spread. This research aimed to use four different vetiver grass (<em>Vetiveria zizanioides</em>) ecotypes to remove cyanide (CN<sup>-</sup>)-contaminated water for improve its quality. Growth capability, tolerance and removal efficiency were evaluated. The results showed that the vetiver grass had a 100% survival rate for one month after planting. Songkhlar3 had the longest leaves, followed by Surat-Thani, Sri Lanka and Monto, respectively. Root lengths of all ecotypes showed no significant differences (p ≤ 0.05). All vetiver grass ecotypes could potentially purify CN<sup>-</sup>-contaminated water at lower concentrations of ≤ 35 mg CN<sup>-</sup>/L. The Monto ecotype had the highest CN<sup>-</sup> removal efficiency at all CN<sup>-</sup> concentration levels, showing 100% CN<sup>-</sup> removal from the 5-45 mg CN<sup>-</sup>/L contaminated water samples within 2-5 weeks growth. The tolerance of vetiver grass to CN<sup>-</sup> was a more important factor than growth rate when selecting a vetiver grass ecotype for CN<sup>-</sup> phytoremediation.</p>

Novel Method

Large amount of dredged sediments has caused a series of social and environmental problems, because of serious heavy metal contamination. A novel method is reported here to recycle the dredged sediments in an eco-friendly manner by combining solidification/stabilization (S/S) treatment and vegetation. In this work, we formulated Portland cement, bontonite and quicklime with fly ash to solidify/stabilize the sediment dredged from a polluted river in Guangzhou, China. The stabilization effect was evaluated, and the influences of S/S products on plant growth were also investigated. The results indicate that S/S products have stable fixing capacities for Cd, Pb, and Ni in the dredged sediment. The results of subsequent plant growth experiment suggest that S/S products could be used as a media to grow plants, and fertilizer to sustain the growth of the plants. Vetiver growing in S/S products would stress on the plants and enhance the expression of enzymes, thus increasing the tolerance of the plants to the stress. Our research on combining S/S product and vegetation has demonstrated that it is feasible to recycle the dredged sediment eco-friendly. S/S product combined with vetiver grass has great potential in ecological restoration.
