Physiological and biochemical alterations induced in the mussel Mytilus galloprovincialis after short and long-term exposure to carbamazepine

  • The bivalve Mytilus galloprovincialis collected in the Ria de Aveiro, was selected to evaluate the acute and chronic effects of carbamazepine (CBZ) at environmentally relevant concentrations. CBZ is an antiepileptic drug widely found in the aquatic environment with toxic effects to inhabiting organisms. However, few studies evaluated the acute and chronic toxicity of this drug. The experiment was performed 'by exposing mussels to 0.0, 0.3, 3.0, 6.0 and 9.0 CBZ mu g/L, for 96 h and 28 days. To assess the toxicity of the drug, a battery of biomarkers related to mussels general physiological health status and oxidative stress was applied. CBZ was quantified in mussel tissues by an Enzyme-Linked Immunosorbent Assay (ELISA). The results obtained show that CBZ did not induce oxidative stress. However, our findings,demonstrated that the drug was taken up by mussels even though presenting low bioconcentration factor (BCF) values (up to 2.2).

However, our findings,demonstrated that the drug was taken up by mussels even though presenting low bioconcentration factor (BCF) values (up to 2.2). Furthermore, our results demonstrated that after a chronic exposure the physiological parameters, namely the condition and gonadosomatic indices, were negatively affected which may impair organisms' reproductive capacity with consequences to population sustainability.zeige mehrzeige weniger
