Laboratory and field studies were carried out in order to assess, in a common cyprinid freshwater fish, the chub (Leuciscus cephalus), the feasibility of biological methods to detect and quantify estrogenic effects. In the laboratory the effects of 1

The impact of a wastewater treatment plant (WWTP) effluent was assessed with the fish biomarker ethoxyresorufin-O-deethylase (EROD) using field and on-site laboratory experiments. EROD activity was measured in chub (Leuciscus cephalus) and stone loac

Effect of Methidathion (organophosphate) on the P450 1A induction was assessed both by measurements of the induction of the EROD activity and of the immunodetection of the CYP 1A protein in gudgeon. Fish were pre-treated with 5 mg/kg of beta-Naphthof

A comparison of ethoxyresorufin-O-deethylase (EROD) data collected in 1995 in various sites in the Rhône watershed (France) was carried out to quantify the influence of factors such as contamination and biological parameters on EROD levels and withi

Storm run-off is a source of acute toxicity leading to fish mortality. The lethal main factors involved are hypoxia and the presence of ammonia. A series of experiments was carried out on juvenile rainbow trout exposed to ammonia and low concentratio

During the draining of dams, realized to remove the sediment from the reservoir, drastic fish mortalities have been observed down-stream in the river. These mortalities are correlated with an increase of the suspended solids and ammonia concentration

International audience; The response of wild fish to pollutants was studied using two biomakers in chub (Leuciscus cephalus) at five stations in the Moselle River (France) in 1998 and in 1999. The induction of cytochrome P450 1A was quantified by the

International audience; A two-step purification protocol was developed to purify rainbow trout (Oncorhynchus mykiss) vitellogenin (Vtg) and was successfully applied to Vtg of chub (Leuciscus cephalus) and gudgeon (Gobio gobio). Capture and intermedia

The toxicology and the chemical quality of three municipal wastewater effluents have been studied. Acute and sub-chronic bioassays were carried out. We also measured the induction of the hepatic ethoxy resorufin-O-deethylase enzymatic activity (EROD)

To improve the preservation of effluent samples, the contribution of refrigeration, freezing, and freeze drying techniques to maintain the toxic characteristics of the samples was evaluated. To achieve this evaluation one acute test, three long term
