Closely-related species of hyperaccumulating plants and

Phylogeny of As, Cd, Cu, Cr, Mn, Ni, Pb, and Zn hyperaccumulators was constructed. • Closely-related plants tend to accumulate similar metals excluding Cd and Pb. • Plant’s ability in metal accumulation cannot be predicted via phylogeny except Ni. • Screening closely-related plant species help to find new hyperaccumulators.

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.

Prediction Models for Bioavailability of Mn, Cu, Zn, Ni

The pH value statistically significantly affected the bioavailability of Ni, Mn, Pb, and Cu also in all prediction models. The impact of SOM and clay varied depending on the model and TEs. Multiple linear regression showed that the prediction models for TE Cu (R2 = 0.763–0.848) were the most reliable and that the bioavailability of Cu was

Screening of metal uptake by plant colonizers growing on

Nine plant species growing over the copper mine site were selected to screen for metal uptake to determine their suitability for phytoremediation. The Australian native tree species Eucalyptus camaldulensis indicated enrichment factor (EF) of 2.17, 1.89, and 1.30 for Cu, Zn, and Pb, respectively, suggesting that this species of tree can

Prediction Models for Bioavailability of Mn, Cu, Zn, Ni

The bioavailability of trace elements (TEs) is one of the major factors for successful plant production and environmental protection. The aim of this study was to determine the extent to which TEs are bioavailable and which of the basic soil parameters affect bioavailability. The survey included agricultural soil samples taken from 240 locations on the territory of the Republic of Serbia

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

Mar 20, 2007· Various extraction procedures were employed for measuring extractable concentrations of potential toxic elements in soil. The extractability of Cd, Cu, Pb and Zn in four contaminated and four non-contaminated soils of Japan, was compared by single extraction (CaCl2, DTPA, NH4Cl, 0.1 M HCl and 1 M HCl ) and sequential extraction procedures [(six operationally defined chemical phases, viz.
