Sažetak
Toxicity Characteristic Leaching Procedure (TCLP) was applied to mercurycontaminated soil from the Idrija region, Slovenia to evaluate the potential soil toxicity. The TCLP test was performed with and without the addition of natural zeolite, iron(III)-modified zeolite or sulphur-impregnated zeolite. Results showed that the soil is extremely polluted and represents hazardous waste. The addition of zeolites significantly reduces the concentration of leached Hg, whereby the most satisfactory results being achieved with sulphur- impregnated zeolite, making it as a potential sorbent for in situ remediation of mercury- contaminated soil.
