Vitellogenin expression in wild cyprinid Petroleuciscus esfahani as a biomarker of endocrine disruption along the Zayandeh Roud River, Iran.

Aquatic environments are the ultimate sink for most of anthropogenic pollutants. The Zayandeh Roud River is the most important river in the central Iranian Plateau, supplying water to a large population. In order to determine the potential occurrence and in vivo effects of Endocrine Disrupting Chemicals (EDCs) with estrogenic or anti-androgenic properties we analyzed the wild populations of an extensively distributed endemic fish species, Petroleuciscus esfahani.
