| Research Abstract |
We developed a profitable phytoremediation technology using biofuel resources plants (BRP) for both utilization and remediation of contaminated soil. To develop this technology, field experiments were carried out in the heavy metal contaminated soil in the eastern, central western and northeastern areas of China, with application of BRPs. Heavy metal contents and their distributions in various organs of BRPs were analyzed, and the remediation efficiency and economic profitability were evaluated. We confirmed that the seeds of BRPs from the contaminated soils we used were suitable for biofuel production. Remediation efficiency and profitability of BRPs were greatly different among areas and BRP species. For each area, excellent BRP species as well as their excellent variety for soil remediation were screened out. Based on the results, we proposed a new strategy of [profitable soil phytoremediation], instead of the conventional [low cost soil phytoremediation].
