Acute effects on hepatic biomarkers in the freshwater native fish Aequidens metae exposed to polycyclic aromatic hydrocarbons by W. Corredor-Santamaría, I.C. Calderón-Delgado, Z. Arbeli, J.M. Navas, Y.M. Velasco-Santamaría

“…In peripheral blood erythrocytes, increased presence of nuclear abnormalities was higher in fish exposed to phenanthrene, followed by benzo[a]pyrene, beta-naphthoflavone, and naphthalene.CONCLUSIONS: It is concluded that Aequidens metae is a suitable bioindicator for polycyclic aromatic hydrocarbons monitoring in aquatic ecosystems. Phenanthrene reveals for the first time a greater genotoxic effect than benzo[a]pyrene at sublethal concentrations. …”
