Heavy Metal Uptake by Two Edible Amaranthus Herbs Grown on Soils Contaminated with Lead, Mercury, Cadmium, and Nickel

摘要: The uptake of an element by a plant is primarily dependent on the species, its inherent controls, and soil quality. Amaranthus hybridus (green herbs) dubius (red were chosen to investigate their response ability accumulate tolerate varying levels elements in roots shoots. Red herbs green grown pots contaminated with three mixtures Cd(II), Ni(II), Pb(II), Hg(II). Plants control treatment absence heavy metals mixture. distribution Cd, Ni, Pb, Hg plants (in roots, stems, leaves) was determined two stages. Stage 1, after 5 weeks growth stage 2, full 10 growth. In red Cd concentration leaves at 2 150 ppm present higher concentrations than Hg, Pb. At highest contamination level, plant, root, i.e., 336 while level 7.12 ppm. Both species showed affinity for Ni moderate high detected leaves, respectively.
