Phenanthrene (PHE) is an abundant polycyclic aromatic hydrocarbon (PAH), widely distributed in aquatic environment. The aim of this study was to evaluate the histological and molecular effects in the native oyster Crassostrea brasiliana(Lamarck, 1819) exposed to 100 and 1000μgL−1 PHE for 1, 5 and 10 days. Histological and chemical analyses were performed to evaluate, respectively, alterations in oyster...
Understanding the toxic mechanisms by which organisms cope to environmental stressful conditions is a fundamental question for ecotoxicology. In this study, we evaluated biochemical responses and hydrocarbons bioaccumulation of the mangrove oyster Crassostrea brasiliana exposed for 96h to four sublethal concentrations of diesel fuel water-accommodated fraction (WAF). For that purpose, enzymatic activities...
