Taking into account the accumulation capacity and tolerance to heavy metals, L.
In general, the changes observed in the morphological and physiological parameters and the formation of products of lipid peroxidation of membranes during the exposure to moderate concentrations (T2) of the mixture of metals did not cause harmful effects to the survival of the species within the first 14Â days of exposure. Thus, this species can be considered as a hyperaccumulator of these metals. laevigatum, and the bioconcentration factor revealed that the concentrations of Ni and Zn in the leaf and root exceeded by over a thousand times the concentrations of those in the culture medium (2000 in leaf and 6800 in root for Ni 3300 in leaf and 11,500 in root for Zn). The accumulation of Pb, Cr, Ni, and Zn in roots was higher than in leaves of L.
In order to study the bioaccumulation of Pb, Cr, Ni, and Zn and the stress response, the floating aquatic plant Limnobium laevigatum was exposed to increasing concentrations of a mixture of these metals for 28 days, and its potential use in the treatment of wastewater was evaluated. Phytoextraction of Pb, Cr, Ni, and Zn using the aquatic plant Limnobium laevigatum and its potential use in the treatment of wastewater.Īrán, Daniela Silvina Harguinteguy, Carlos Alfredo Fernandez-Cirelli, Alicia Pignata, MarÃa Luisa
