The freshwater mudsnail (Potamopyrgus antipodarum) is sensitive to toxicity of both sediment and water and also to the endocrine disrupting compounds (EDC) at environmentally relevant concentrations. This study determined effects of in situ exposure of P. antipodarum as a part of a complex assessment of the impact of a city metropolitan area with large waste water treatment plant (WWTP) for 0.

They have not been monitored systematically in the Czech Republic. The goal of the present study was the characterization of aquatic environmental pollution from the Brno (Czech Republic) city agglomeration focusing on EDC.

Seven locations on the Svitava and Svratka rivers (in the Brno conurbation, Czech Republic) were assessed.

Design: Levels of 1-OHP were determined by reverse phase HPLC with fluorescence detection. For valid assessment of bile accumulation levels, the 1-OHP concentration was normalized to the biliary protein content.
