Comparative ecotoxicity of interstitial waters in littoral ecosystems using microtox~R and the rotifer brachionus plicatilis

摘要

The toxic effects of sediment interstitial waters from seven littoral sites in the Gulf of Cadiz were tested with the Microtox~R assay and a 7-d Brachionus plicatilis (Rotifera) decline test. Dissolved organic carbon (DOC), nutrients (ammonia, phosphate, nitrate, nitrite, and silicate), the heavy metals (Fe, Mn, Zn, Cu, Pb, Cr, and Cd), and the linear alkylbenzensulfonate (LAS) concentrations in the interstitial water were measured. The results of assays were compared in a dose-response relationship between sites.
