Solubility control of Cu, Zn, Cd and Pb in contaminated soils

A stirredflow method was used to study the kinetics of Cd, Cu, Ni, Pb, and Zn adsorption and desorption in multiple soils under various pH and metal concentrations, and the model successfully

Screening and Evaluation of the Bioremediation Potential

As expected, the presence of bacteria resulted in increased concentrations of watractable Cu, Zn, Pb, Cd, and Fe in autoclaved soil compared to axenic soil (Figure Figure2 2). These results suggest that the 10 Cu/Znresistant isolates had metalsolubilizing potential in heavy metalpolluted soil, thereby increasing metal bioavailability.

Immobilization of Zn, Cu, and Pb in contaminated soils

bilization of other metals (e.g., Cu, Zn, and Cd) [5,1517]. A single amendment may not be suitable for multiple metals and the treatment effectiveness depends on assessment methods [1820].For example, addition of P to a soil contaminated with Pb, Zn, and Cd reduced the bioavailable Pb, but increased plant Cd concentrations [19

Immobilization of Zn, Cu, and Pb in contaminated soils

The phytoavailability of Cu and Zn was positively correlated to their water solubility (r = 0.907 and 0.825 for soybean Cu and Zn, respectively r = 0.946 and 0.861 for lettuce Cu and Zn, respectively). Among the three metals, P amendments were effective in reducing Pb phytoavailability, compared to Cu and Zn.

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 nondetectable to as high as 1183 mg kg 1, with the maximum being in the roots of Phyla nodiflora from site 4 ().

Assessment of the Bioavailability of Cu, Pb, and Zn

Trace metals (Zn, Cu, and Pb) in the soils were partitioned by a sequential extraction procedure into H 2 O extractable (F1), 1 M CH 3 COONa extractable (F2). Chemical fractionation showed that F1 and F2 fraction of the metals was near 1% and residual form was the dominant for Zn, Cu, and Pb in all samples.
