"Laboratory-reared cultures of Enchytraeus crypticus were used in a reproduction toxicity test to evaluate the toxicity of 46 spoil substrates collected in four brown coal mining areas in the Czech Republic and Germany. A set of substrate parameters (pH, conductivity, Na, Ca, K, Al, Fe, loss of ignition and polyphenol contents) were measured for each spoil and correlated with spoil toxicity for E. crypticus. Toxicity increased with decreasing pH and increasing Al, Fe content. Spoil with a pH below 3 did not support the survival of E. crypticus. However, some alkaline spoils with high conductivity and ion concentration were also toxic. Toxicity was positively correlated with the loss of ignition and polyphenol content. The results indicate that the toxicity of post-mining spoil substrates have multiple origins. Most frequently the toxicity of post-mining substrates corresponds with low pH and consequent toxicity of Al and Fe." . . . . . . . . .
