Abstract
This study concerns the research relating lead mobilization from artificially polluted soil by using EDTA ligand (ethylene diamine tetra acetic acid).Experimental research in Green House were designed to check the reproducibility of analysed parameters on the selected plant (maize) and the conclusions of the preliminary test laboratory experiments.The checking consisted in two experiments achievement with 2 degrees ofartificial loading soil with Pb: 1000 mg Pb/kg soil and concentration of EDTA in ratio Ligand/Lead between 0 and 0.5 and 2000 mg Pb / kg soil and ratio Ligand/Lead between 0 and 0.4 and three growing cycles (Cycle 1, Cycle 2 - residual effect, Cycle 3 - residual effect).The paper will present experimental results obtained in Cycle 3, remanent effect.
