文摘
Liming decreased Cd, Mn and Zn solubility in slightly acidic soils but not Cu and Pb. Liming decreased Cu, Cd, Pb and Zn solubility in strongly acidic soils but not Mn. Phragmites favored metal enrichment in surface soils due to water pumping stimulation. Phragmites favored metal mobilization in deeper soils by hindering the drop of Eh. Remediation success depended on target metal, soil type, hydric regime and vegetation.
