Phytoextraction of Cadmium, Lead and Nickel from a Contaminated Soil by, Hordeum Vulgar L. and Brassica Napus L.
Heavy metals contamination is a major environmental problem which requires immediate human attention. The use of plant species to remove pollutants from soils, generally defined as phytoextraction. In order to evaluate phytoextraction of contaminated soils, a pot experiment conducted using two plants Barley, Canola three kinds of heavy metals (Cd, Pb, Ni) with 3 levels in a completely randomize...

متن کاملChelate-Assisted Pb Phytoextraction: Pb Availability, Uptake, and Translocation Constraints
Chelates have been shown to enhance phytoextraction of Pb from contaminated soil. Mechanisms behind this phenomenon, however, remain largely unexplored. In this paper we examine chelate effect on Pb dissolution, plant Pb uptake, and internal plant Pb translocation. EDTA was found to be the most efficient in increasing watersoluble Pb concentration in our test soil. Unfortunately, PbEDTA is high...
متن کاملUse of Festuca ovina L. in Chelate Assisted Phytoextraction of Copper Contaminated Soils
Festuca ovina L. is a hyperaccumulating plant which has aroused considerableinterest with respect to its possible use for phytoremediation of contaminated soils. Thisstudy has been conducted to evaluate the potentials of F. ovina L. to serve as aphytoremediation plant in the cleaning up of Cu in the polluted soils and to identifyextraction efficiency of Ethylene Diamine Tetraacetic Acid (EDTA) ...
متن کاملAssessment of the Efficacy of Chelate-Assisted Phytoextraction of Lead by Coffeeweed (Sesbania exaltata Raf.)
Lead (Pb), depending upon the reactant surface, pH, redox potential and other factors can bind tightly to the soil with a retention time of many centuries. Soil-metal interactions by sorption, precipitation and complexation processes, and differences between plant species in metal uptake efficiency, transport, and susceptibility make a general prediction of soil metal bioavailability and risks ...
