Estimation of Copper and Cadmium Bioavailability in Contaminated Soil Remediated by Different Plants and Micron Hydroxyapatite

Figure 1

Total Cu and Cd concentrations in five soils during 3 years. MW = Setaria lutescens, ME = Elsholtzia splendens, MS = Sedum plumbizincicola, and MP = Pennisetum sp. Different lowercase letters indicate significant differences in the same treatment during the three years (n = 3, ).
