Última Pb-phytoextraction by maize in a Pb-EDTA treated Oxisol Scientia Agricola Pereira,Bruno Fernando Faria; Abreu,Cleide Aparecida de; Romeiro,Solange; Lagôa,Ana Maria Magalhães Andrade; Paz-González,Antônio. One of the most viable strategies to restore metal contaminated soils is the introduction of plants specialized in their accumulation or able to tolerate very high metal concentrations. This research evaluated: i. the maize as a Pb-accumulator plant; ii. the effects of EDTA-chelating agent for Pb-uptake by maize; iii. amending effect of EDTA on the soil Pb-availability using different extracts. Treatments consisted of Pb rates (100; 200; 350; 1,200 and 2,400 mg kg-1) applied to a Rhodic Hapludox in the form of Pb3(NO)2 with (0.5 g kg-1) and without EDTA. Lead concentrations were determined in maize plant shoots. Soil available Pb was obtained using DTPA, Mehlich-3 and saturation solutions methods. Ionic speciation in the soil solution was performed using... Tipo: Info:eu-repo/semantics/article Palavras-chave: Mehlich-3; DTPA; Phytoremediation; Available Pb; Ionic speciation.

A greenhouse study was conducted to evaluate the effects of ethylenediamine tetraacetic acid (EDTA) addition to soils on the lead (Pb) phytoextraction potential of jack beans (Canavalia ensiformis L.). In a pot experimentSoil samples (dystrophic Rhodic Hapludox) were treated with six Pb rates (0, 100, 200, 350, 1,200, and 2,400 mg kg-1 soil) applied as Pb(NO3)2 without and with EDTA application (0 and 0.5 g kg-1, respectively). Lead, Cl-, NO3-, NH4+, SO4(2-), H2PO4-, Zn2+, Cu2+, Fe3+, Al3+, Ca2+, Mg2+, K+ and DOC (dissolved organic carbon) concentrations obtained in a saturation soil extract (soil:water ratio of 1:0.3) were used for Pb speciation by means of the software Visual-Minteq 2.30. Soil Pb-availability was assessed with Diethylene triamine... Tipo: Info:eu-repo/semantics/article Palavras-chave: Ionic speciation; Phytoextraction; Soil pollution; Soil solution; Chelate.
