Using a laboratory culture of Enchytraeus crypticus (Oligochaeta) for evaluation of toxicity of spoil material after brown coal mining - preliminary results.

Popis výsledku v původním jazyce

Laboratory reared cultures of Enchytraeus crypticus were used to evaluate toxicity of spoil material from two coal-mining areas - the Lusatian Mining district near Cottbus, Germany and the Sokolov coal mining district in the Czech Republic. The spoil material near Cottbus is mostly sandy, whereas clays prevail near Sokolov. During the tests, enchytraeids from laboratory cultures were added to various spoil substrates and control meadow soil (20 potworms per container) and cultivated for 5 weeks. Oak flakes were used as food. Populations up to 808 specimens of E. crypticus per container developed during five weeks in the control soil. The spoil substrates yielded remarkably different potworm populations (from 0 to 644 potworms). The coal rich clay, tertiary and acidic sands were the most toxic substrates. The toxicity of spoil substrates closely corresponded with pH. No E. crypticus survived in substrates with pH below 3. In substrates with low pH, the increase of pH by liming and addit
