The objective of this work was to evaluate the effectiveness of a plant bioassay (Phytotoxkit®) for screening ecotoxicological risks in sediments affected by mining activities. Materials and methods A total of 42 sediment samples affected by mining activities were studied, including 39 sediment samples fromthe Sierra Minera, Spain, an area affected by old extraction procedures, and three sediments from an area affected by opencast mining. These three samples were then mixed with limestone filler at 10, 20 and 30 %, providing nine stabilised samples. The total and soluble metal(loid) content (As, Cd, Cu, Fe, Pb and Zn) was determined in all samples, and the Phytotoxkit® bioassay was applied to determine the ecotoxicological effect of this procedure. Results and discussion The stabilised material had a neutral pH and low soluble metal(loid) concentration, similar to that of samples in which a natural attenuation process had taken place because of mixing with surrounding carbonate-rich materials. An ecotoxicological survey identified the low toxicity levels of the stabilised samples. 1439-0108 10.1007/s11368-014-0942-0 https://hdl.handle.net/20.500.14352/34175 https://www.springer.com/journal/11368/ Application of a plant bioassay for the evaluation of ecotoxicological risks of heavy metals in sediments affected by mining activities
