The use of chloride salts during phytoextraction of heavy metals from a contaminated soil

Original language description

This study was focused on the use of soil-applied chloride salts (NH4Cl) during phytoextraction of heavy metals from contaminated soils. The applied chloride salts proved to be a successful phytoextraction-enhancing agent only for Zn and poplar. The addition of NH4Cl did not significantly enhance the phytoextraction of Cd, with the only exception of 20 mmol.kg-1 applied to maize and 30 mmol.kg-1 applied to poplar. The results suggest that especially poplars could be used in Cd phytoextraction without any addition of mobilising agents which could lead to unwanted leaching. Chloride salts were not effective at enhancing Pb phytoextraction efficiency. All these facts make the use of chloride salts unsuitable for a chemically enhanced phytoextraction of heavy metals from soils contaminated by multiple metals originating from the smelting industry.
