Abstract:To further understand heavy metal behaviors in soil and interaction effect on plant uptake, a pot experiment in an orthogonal experiment design with cadmium (Cd), zinc (Zn) and lead (Pb) under mono- and multiple contamination conditions was carried out based on the experiments of sensitivity to heavy metals. Two susceptible plants, Medicago sativa and Elymus dahurian Turuz were tested. Biomass and absorption to three heavy metals: lead, cadmium and zinc was first tested in mono-contamination conditions, and...
