Of the bioassays used in this study, the ostracod test was the most responsive. Vibrio fischeri luminiscence inhibition assay was less sensitive to the toxicants in the sediments than the phytotoxicity assays. The general trend observed was an increase in toxicity values measured by the bioassays with increasing metal mobilization in sediment samples. Therefore, the test battery can be used as a rapid and sensitive tool to evaluate the heavy metal contamination in sediments.engjournal articlehttp://dx.doi.org/10.1007/s10646-009-0362-xrestricted access631.4614.7:622Heavy metalMicrotoxOstracodsPhytotoxicitySedimentsEdafología (Geología)Mineralogía (Geología)2511 Ciencias del Suelo (Edafología)2506.11 Mineralogía
