A lysimeter approach (under natural climatologic conditions) was used to evaluate the effect of four metal immobilizing soil treatments [compost (C), compost + cyclonic ashes (C + CA), compost + cyclonic ashes + steel shots (C + CA + SS)) and cyclonic ashes + steel shots (CA + SS)] on metal leaching through an industrially contaminated soil. All treatments decreased Zn and Cd leaching. Strongest reductions occurred after CA + SS and C + CA + SS treatments (Zn: −99.0% and −99.2% respectively; Cd: −97.2% and −98.3% respectively). Copper and Pb leaching increased after C (17 and >30 times for Cu and Pb respectively) and C + CA treatment (4.4 and >3.7 times for Cu and Pb respectively). C + CA + SS or CA + SS addition did not increase Cu leaching; the effect on Pb leaching was not completely clear. Our results demonstrate that attention should be paid to Cu and Pb leaching when organic matter additions are considered for phytostabilization of metal contaminated soils. When applied in combination with compost not all inorganic soil amendments were able to compensate increases in Cu and Pb leaching caused by compost addition.
