UPTAKE OF HEAVY METALS BY ALFALFA (Medicago sativa L.): POT EXPERIMENT

Abstract

In this work, the uptake of some heavy metals (Cd, Cr, Cu, Ni and Pb) by alfalfa (Medicago sativa L.) was studied in a pot experiment. Alfalfa and soil samples were prepared by wet digestion and analyzed by ICP-OES. The obtained results were discussed based on the determined concentrations, translocation factors (TFs) and enrichment factors (EFs) values, showing that this plant species is able to uptake increased amounts of Cd by roots.
