Suitability of some ecotoxicological tests to predict the behaviour of haza
rdous wastes elutes under environmental conditions is investigated. Slags,
ashes and filter dusts from municipal and hazardous waste incineration plan
ts were eluted with salt brine, groundwater and aqua dest., simulating unde
rground disposal in salt mines, in coal mines and above ground disposal in
landfill sites. Garden cress, duckweed, green algae, toxicity and genotoxic
ity of luminescent bacteria, and inhibition of the respiration of waste wat
er bacteria were applied. Incineration residues of hazardous wastes were mu
ch more toxic on the plants (EC50: 0.1-0.7 ml/l) than the ones of the munic
ipal waste incineration (EC50: 20-200 ml/l). The luminescent bacteria were
usually the most sensitive one for the MWIP residues (EC50: 0.2-2.4 ml/l).
