摘要

The aim of this work was to evaluate the capacity of mineral wools for stabilizing Cu, Pb, Zn and Cd of soil contaminated by metallurgical activity. Specifically, this study was undertaken in order to determine the usefulness horticultural post exploitation of mineral wool for soil remediative purposes. Two mineral wools have been considered: after horticultural exploitation (Wool_(Exp).) and unused wool (Wool_(Ref)). They were tested for pH, EC (electrical conductivity), TDS (total dissolved solids). Moreover, total heavy metals and reactive forms (extracted in 0.11 moles CH_3COOH, i.e., first BCR fraction) were assayed. A medium-textured highly contaminated soil (collected in the vicinity of the Miasteczko Slaskie Zn/Pb smelter, Poland) was used for the incubation test, in order to verify the usefulness of these wools for remediating soils contaminated by heavy metals. The soil was thoroughly mixed with both wools (i.e., Wool_(Exp). and Wool_(Ref).) at the ratios 0, 0.25, 0.50, 1.0 and 2.0% (dry weight basis). Data showed that the content of reactive forms of Cu, Pb, Zn and Cd decreased along with increasing mineral wool rates. This process was most pronounced for treatments where exploited wool (i.e., Wool_(Exp)) was incorporated. Results showed that this wool exhibited higher sorptive capacity resulting in the retention of much more metals, particularly lead (Pb). In terms of stabilization efficiency (Ef_(Stab)) values, it should be mentioned, that the higher these values, the lower the amounts of extracted Cu, Zn, Pb and Cd reactive forms, and reversely. This was indicative of higher sorption and retention properties of the treatments (i.e., soil and wools). The Wool_(Exp). showed higher usefulness for remediation goals of soils contaminated by heavy metals. Treatments with 0.50 and 1.0% Wool_(Exp). exhibited higher stabilization efficiency.
