Restoration of marginal soils polluted with heavy metals to agricultural production

摘要: The purpose of the study was to assess possibility cultivation maize (Zea mays L.) on marginal soils polluted by heavy metals. research conducted a Stagnic Luvisol soil that varied in terms pH and degree metal (cadmium [Cd], copper [Cu], zinc [Zn]) contamination. usefulness for contaminated assessed basis indicators such as tolerance index (TI), translocation factor (TF), bioaccumulation coefficient (BAC), bioconcentration (BCF). Heavy metals taken up plant are accumulated mainly roots small amount transported aboveground parts plant. series decreasing concentration (Cd, Cu, Zn) dry mass plants is follows: > leaves stalk ears. TF, BAC, BCF values indicate can be used phytoextraction Cd Zn, phytostabilization Cu with this element.
