The shoot biomass of giant reed grown on soil contaminated with As, Cd and Pb amending with soil amendments was presented in Fig. 1. Shoot biomass with respect to low level (1.25 mmol/kg) and middle level (2.5 mmol/kg) of AA varied slightly as compared to that for the control (12.6 g/pot), while that from the treatment with high level (5.0 mmol/kg) of AA was significantly decreased by 34.2% (P < 0.05). Plant shoot biomass increased with the increasing level of CA addition, which was enhanced by 14.2% and 24.8% in middle and high level treatment as much as the control, respectively,while a significant decrease of 28.7% was observed atlow level treatment (P
