Abstract An ecotoxicological analysis of a scrubbE3r dust slurry known as Theisenschlamm was performed. Seepage water from a Theisenschlamm pond and water samples from the receiving riverine system Bose Si1eben were investigated. The toxic potential of the samples was assessed by using a b1acterial luminescence test, the pollen tube growth assay, and in vitro determinations of cytotoxicity and 7-ethoxyresorufin-0- deethylase as a marker of the PAH-induc:ible cytochrome P4501A system. With all
test systems, the seepage water showed massive toxicity. As indicated from EDTA complexation experiments, this effect wais at least partly caused by the high Zn contents of the seepage water. In the water samples of the Bose Sieben, only moderate levels of acute toxicity were observed. However, all samples clearly induced the activity of 7-ethoxyresorufi ni-0-deethylase. This result points to the presence of substantial levels of bioavailable PAHs in the seepage water and the receiving riverine system.
