Chelate-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 ...

متن کاملHeavy Metal Accumulation in Urban Soil: a Phytoextraction Method Review
Lead (Pb), cadmium (Cd), and arsenic (As) are three common non-essential heavy metals found in urban soils and can prove toxic to animals, humans, and some plants at low concentrations. The main exposure pathways of heavy metals in humans are through ingestion and inhalation of soil particles and ingestion of contaminated food. When dealing with contaminated soil in urban environments, activiti...
