• Accumulation of Pb, Cu, and Zn in native plants growing on

    Sep 15, 2006· In this study, a total of 36 plant samples of 17 species was collected from 10 locations at the site. Concentrations of Pb, Cu and Zn in soils and plant biomass are provided in Table 2, Table 3, Table 4.Total Pb concentrations in the plants ranged from non-detectable to as high as 1183 mg kg − 1, with the maximum being in the roots of Phyla nodiflora from site 4 ().

  • Transfer of Cd, Cu, Ni, Pb, and Zn in a soil‐plant

    The transfer of Cd, Cu, Ni, Pb, and Zn was evaluated in a soil‐plant (lettuce, Lactuca sativa )–invertebrate (snail, Helix aspersa ) chain during a microcosm experiment.Two agricultural soils, polluted and unpolluted, were studied.

  • Variability and relationships between Pb, Cu, and Zn

    Concentrations of Cu in the litter leachate were correlated with dissolved organic C (DOC), whereas Zn and Pb were mainly related to leachate pH. Metal concentrations in the soil solution were weakly influenced by their total content in soils and the monthly fluctuations reached 300, 600, and 700% for Cu, Pb, and Zn, respectively.

  • Phytoextraction of Cd, Cu, Pb and Zn by the plant species

    In highly polluted soil, Datura innoxia reduced by 10.63%, 120%, 34.67% and 44.27% respectively an initial Pb concentration of 125 mg / kg, Cd of 0.58 mg / kg, Cu of 208.48 mg / kg and in Zn of 139.83 mg / kg. Conclusion: Datura innoxia is an excellent candidate for the phytoremediation of Pb, Cd, Cu and Zn.

  • Accumulation properties of As, Cd, Cu, Pb and Zn by four

    Above- and below-ground parts of Salix (mixed tissue from S. phylicifolia and S. borealis), Carex rostrata, Eriophorum angustifolium, and Phragmites australis were sampled and analysed for Cd, Cu, Zn, Pb and As. Differences in uptake and translocation properties of the same plant species were observed between field-grown plants and plants grown
