Abstract
There are many farmlands been contaminated with heavy metal (HM) in central Taiwan resulted from the irrigation using river water contaminated with HMs. According to the Soil and Groundwater Pollution Remediation Act (SGWPR Act) of Taiwan, these lands can not planting edible crops until suitable techniques are conducted to decrease the total concentration of HM in soils to conform to the Soil Control Standard (SCS). However, some of the foliar crops still accumulated high concentration of HM in the edible parts even the concentration of HM of the remediated sites is below the SCS. Planting suitable crop species is especially important in this situation and these contaminated sites after remediation can be reused. Soybean, a biomass crop further used to produce biodiesel, seems feasible to plant in the farmlands in this situation. This manuscript reports previous results used pot experiments to investigate the accumulation of HM by various parts of soybean planted in the artificially cadmium- (Cd-), copper- (Cu-), or zinc (Zn-) contaminated soils with different concentrations. The aim is to assess the feasibility of planting soybean in the HM-contaminated soils to produce biodiesel.
