Description	Six kinds of amendments were added to contaminated soil with the goal to alter the mobility of heavy metals and to modify potential environmental impacts. The following amendments were used at doses ranging from 1 to 5%: Two kinds of young brown coals (lignite, oxihumolite) with a high content of humic acids, two commercially available derivatives of humic acids (potassium humate, iron humate), and two inorganic materials (fly ash, natural zeolite). Leachability of heavy metals (Cd, Cu, Pb, Zn) from untreated and amended soils was studied with the aid of a standardized sequential extraction test (BCR test). Cd was present predominantly in the readily mobilizable (acid-extractable) form in the soil; its mobility was reduced effectively after an addition of potassium humate. Cu, Pb and Zn were bound more strongly to the soil matrix. The mobility of Cu was reduced after an addition of inorganic amendments (zeolite, fly ash), whereas potassium humate was effective in the immobilization of Pb. Most of Zn ( Six kinds of amendments were added to contaminated soil with the goal to alter the mobility of heavy metals and to modify potential environmental impacts.
