Abstract Sewage sludges from 19 Polish municipal treatment plants were investigated. Lysimeter leaching experiments on sludges and on sludge-quartz sand mixtures were made. A variety of plants was sowed in the lysimeters and the leachates were collected. Harvested plants as well as leachates were analysed for Pb, Cu, Cd, Ni, Zn and Cr concentration. Removal coefficients were established to characterize the mobility of these metals from the sludges. The high values of the correlation coefficient for cadmium and nickel suggested that water solubility of metal salts is mainly responsible for their mobility.
