Combination contamination of heavy metals is one of important soil contamination types. A greenhouse experiment was carried out to determine the degree of tolerance of Pteris vittata L. to Pb, Cu, and Zn and whether it could be applied to phytoremediation and revegetation of soils contaminated with As and other heavy metals such as Pb, Cu, and Zn. In the presence of As with 400 mg/kg, they were added at rates of 0, 250, 500, 1000, 1500, 2000 mg/kg of Pb as Pb(CH_3COO)_2), 0, 500, 750, 1000, 1500 mg/kg of Cu...
