TL;DR: Two bacterial tests employing Photobacterieum phosphoreum (Microtox bioluminescence test) and Salmonella typhimurium TA 1535 pSK1002 (umu-assay) were evaluated to estimate the cytotoxic and genotoxic potential of water samples from the selected rivers in Germany as well as the primary and secondary effluent of some sewage treatment plants.

TL;DR: After intra muscular injection of DA at the concentrations ranging from 1-500 ng/g body weight (bw), no neurotoxic effect was detected within incubation times of 48 h and 7 d, and the vitality of haemocytes remained in all mussels at the level of control samples within 48 h, and increased significantly after 7 d.

TL;DR: The results of the in vitro screening assays suggest the occurrence of a fast mobilization of applied ECDs and a moderate retardation effect of native E CDs contained in applied SS in the sandy soil used in the lysimeters.

TL;DR: In this paper, two short term bioluminescence inhibition assays based on Vibrio fischeri (Microtox ® and ToxAlert ® 10 tests) were used for the estimation of the cytotoxicity of several European wastewaters from Germany, Spain and Sweden during a field experiment carried out in Berlin (Germany) organized by the Environment and Climate program of the European Commission.

TL;DR: It is concluded that derivatization may mask the apparent estrogenicity of nonylphenol, but the resulting compounds still represent a potential hazard since they are still able to bind the estrogen receptor and to influence the physiological response to estrogens.
