Heavy metal soil pdf

Therefore, the ability of various crop plants to accumulate Pb in shoots and roots was compared. This property may be exploited for soil reclamation if an easily cultivated, high biomass crop plant able to accumulate heavy metals is identified.

Please enter a number between 1 and 2 of 2. Sorption mechanisms in soils, the influence of surface functional groups and surface complexation as well as parameters influencing adsorption are discussed. AbstractThe article focuses on adsorption of heavy metal ions on soils and soils constituents such as clay minerals, metal (hydr)oxides, and soil organic matter.

The high metal accumulation by some cultivars of B. juncea suggests that these plants may be used to clean up toxic metal-contaminated sites in a process termed phytoextraction.

AbstractA small number of wild plants that grow on metal-contaminated soil accumulate large amounts of heavy metals in their roots and shoots.

Empirical and mechanistic model approaches for heavy metal adsorption and parameter determination in such models have been reviewed. The individual adsorption behavior of Cd, Cr, Pb, Cu, Mn, Zn and Co on soils and soil constituents is reviewed.
