Method for screening Cu, Zn, or Pb phytotoxicity on 20171019ensp;0183;ensp;each TM and species the concentration at which plant growth is reduced by 50% (LD50). For switchgrass, the biomass was reduced by 50% when 210 181;g of Cu, 1010 181;g of Zn, or 1500 181;g of Pb was added to the substrate. For reed canarygrass, the biomass was reduced by 50% when 525 181;g of Cu, gt;1050 181;g of Zn, or 2175

  • Assessment of airborne heavy metal pollution using

    201221ensp;0183;ensp;Robinia pseudoacacia L. (Fabaceae) was evaluated as a possible bioindicator of airborne heavy metal pollution, which originates from mining and pyrometallurgical copper production in Bor (Eastern Serbia).Concentrations of Cu, Zn, Pb, Cd, As and Hg were determined in different plant organs (washed/unwashed leaves, branches, roots) and topsoil of R. pseudoacacia by ICPAES and by AAS.

  • Comparison of extractability of Cd, Cu, Pb and Zn with

    Cd, Cu, Pb and Zn in the soils varied from 0.7 to 12.5, 23 to 133, 19 to 359 and 90 to 704 mg/kg, respectively. Generally the concentrations of most metals were 5 to 18 fold higher in the contaminated soils than the noncontaminated soils (Table 1). Metals extractability As expected, 1 M HCl was the most efficient extractant (Table 3).

  • Screening of native plants from wasteland

    Specifically, an individual Symphytum officinale Linn. plant can accumulate up to 5.54, 21.0, and 52.9 mg Cd, Pb, and Zn in its aboveground parts (20.67 g dry weight). Results from this study can provide a reference for the phytoremediation of PTMs contaminated soil in this area or other places with similar soil and climate conditions.

  • Screening of Native Plants Growing on a Pb/Zn

    Screening of native plant species from mining sites can lead to identify suitable plants for phytoremediation approaches. In this study, we assayed heavy metals tolerance and accumulation in native and dominant plants growing on abandoned Pb/Zn mining site in eastern Morocco. Soil samples and native plants were collected and analyzed for As, Cd, Cu, Ni, Sb, Pb, and Zn concentrations.
