Summary:The effects of the characteristics of different soils were evaluated in terms of the suitability of test species and the influence on the toxicity of copper. The test species were Enchytraeus albidus, E. luxuriosus, and Folsomia candida, which were exposed to fresh and aged soils spiked with Cu chloride. The main characteristics of the tested soils, including pH, organic-matter content, carbon:nitrogen ratio, clay content, silt content, sand content, cation-exchange capacity, and water-holding capacity, are tabulated. Results revealed that the soil properties affected the toxicity of Cu toward all three species, but no relationship with any specific soil parameter was discerned. Only F. candida was affected by soil aging, but the enchytraeids were more sensitive to Cu than F. candida.
