Accumulations of As and Cd in plant significantly increased with the addition of 2.5 mmol/kg
AA and CA, 5.0 mmol/kg EDTA, and 4.0 g/kg sepiolite, and the shoot Pb accumulation was enhanced obviously by amending with 4.0 mg/kg sepiolite and 8.0 mg/kg phosphogysum, respectively as compared to the control. The results suggested that AA, CA and sepiolite could be considered optimum soil amendments for giant reed remediation system.
