  • accumulation of pb, cu, and zn in native plants growing on

    among the 36 plants collected from 10 locations, p. nodiflora from site 4 accumulated the highest pb, cu and zn in the roots 1183, 460, and 598 mg kg 1, respectively . in addition, g. pennelliana and b. alba showed higher concentrations of pb, cu and zn than other species.

  • heavy metal pb, zn, cd, fe, and cu contents of plant

    in addition to pb and zn, the primary ore constituents, copper cu , iron fe , and cadmium cd , were also assayed. as expected, foliar pb and zn concentrations were elevated in plants at the sites closest to the mill, i.e., 0.25 and 2.5 km from the mine facility.

  • 'screening the phytoremediation potential of native plants

    the concentration of cu, pb, mo, zn, as, and cr was determined in the roots and shoots of plants grown at the site. several species of local shrubs and grasses were sown in the soil-covered tailing. screening the phytoremediation potential using native plants to clean up such a mine tailings as in globe, arizona, usa, was investigated in
