摘要: A sediment contact test (SCT) battery consisting of five ecotoxicological systems was applied to 21 native freshwater sediments characterized by a broad variety geochemical properties and anthropogenic contamination. Higher plants (Myriophyllum aquaticum), nematodes (Caenorhabditis elegans), oligochaetes (Lumbriculus variegatus), zebrafish embryos (Danio rerio), bacteria (Arthrobacter globiformis), representing various trophic levels exposure pathways, were used as organisms. The detected toxicity caused pollution, whereas the tests provided site-specific, nonredundant information overall assessment. Based on pattern derived from battery, classified according newly proposed classification system for SCT-derived generally agreed well with application consensus-based quality guidelines (SQGs), especially regard high toxic potential. For low medium potential, SQGs often underestimated that SCTs, underpinning need in Environ. Toxicol. Chem. 2013;32:144–155. © 2012 SETAC
