Influence of ozonation on extractability of Pb and Zn from contaminated soils

Original language description

The effect of soil ozonation on Pb and Zn extraction with EDTA, bioavailability (Ruby`s Physiologically Based Extraction Test, PBET) and mobility (Toxicity Characteristic Leaching Procedure, TCLP) of Pb was studied on contaminated soils taken from 7 different locations in the Mežica Valley, Slovenia. EDTA extraction (40 mmol.kg-1) removed from 27.4 ? 1.5% to 64.8 ? 1.5% of Pb, and from 1.9 ? 0.2% to 22.4 ? 2.0% of Zn from tested soils, and significantly reduced soil Pb bioavailability (PBET) and mobility (TCLP). Pretreatment of tested soils with ozone before EDTA extraction enhanced EDTA extractability of Pb for 11.0 to 28.9%, but had no effect on extractability of Zn. In most of the soils, ozonation had no statistically significant effect on bioavailability and mobility of Pb, residual after EDTA extraction. Using linear regression analysis we found a significant increase (p<0.01) in EDTA extractability of Pb after ozonation in soils with a higher initial Pb content. We found no corre
