Five representitative samples of heavily polluted soil from a former industrial area in Celje (Slovenia) containing 7300 - 17200 mg kg-1 total Pb, 6000 - 63600 mg kg-1 total Zn and 24 - 250 mg kg-1 total Cd were remediated with the stabilization method with 15 % (w/w) portland cement. After 4 months of stabilization the mobility of Pb, Zn and Cd assessed with Toxicity Characteristic Leaching Procedure (TCLP) decreased by factors 5.8 - 17.4, 8.1 - 35.8 and 4.3 - 7.3, respectively. Potential availability of Pb, Zn and Cd for plants assessed with dietilentriaminpentaacetic acid (DTPA) extraction decreased by factors 1.6 - 9.8, 1.1 - 2.1 and 1.3 - 4.1 after stabilization, respectively. Bioacessibility of Pb assessed with a physiologically based extraction test (PBET) decreased after stabilization by factors up to 11.3 in the small intestine fraction.
