Remediation of metals-contaminated soils
Four soils from an industrial area were analyzed for contents of Zn, Cd, Ni, Cr, Pb and Cu and then phytoremediated by using Festuca rubra L., Festuca ovina L., Lolium perenne L. and Poa pratensis L. grasses. The metal contents in soils decreased in series Pb > Zn > Cu > Cr > Ni > Cd. The soilage (3 swaths) was studied for contents of the removed metals. The metal contents in the grass biomass decreased in series Zn > Cu > Pb > Cr > Ni > Cd. The contents of Zn, Cd and Pb in grass were higher than allowable in fodders.
