Abstract

Phytoremediation is a new technology used for remediation the agricultural and industrially soils contaminated/polluted with heavy metals. One of the phytoremediation techniques, the so- called phytoextraction, is a method to extract heavy metals from contaminated/polluted soils using hyperaccumulators plants and to translocate them to shoots. This case study presents the effects of ethilene diamine tetraacetic acid (EDTA) application as a potential amendment for an artificial contaminated soil with Pb to enhance the translocation capacity in the harvestable plant parts of maize. The treatments consisted in the application of some Pb concentrations (1000 mgPb·kg -1 , 2000 mgPb·kg -1 , 3000 mgPb·kg -1 ) in combination
