ABSTRACT
Among the chemicals found in the aquatic environment, some have been reported to interact with the endocrine system of organisms and have been identified as endocrine disrupting compounds. In this study, we have assessed the biological effects due to environmental estrogenic compounds in adult male roach (Rutilus rutilus). Wild fish were collected in the Seine River, and one of its affluent, the Epte River in Normandy, France and impacts on endocrine and reproductive functions have been assessed. This study provides innovative data on the intersex condition in wild fish that are crucial to understand estrogenic contamination impacts and maintenance of sustainable fish population. The biomarker responses found in fish from contaminated sites included high plasmatic vitellogenin concentrations, altered steroid levels, histopathological and up to 50% intersex fish among the male. However, the overall sex ratio of the roach population indicated sign of feminization with some sites showing only 20% of males. The chemical organic contamination at the different location sites has been characterized by the levels of PAHs, PCBs and phthalates and total estrogenic activity was measured by the YES in vitro assay.
