Glutathione S-tranferases and cytochrome P450 activities in Mytilus galloprovincialis from the South coast of Portugal: Effect of abiotic factors

Environmental impact on the antioxidant responses inCorbicula fluminea(Bivalvia: Veneroida: Corbiculidae) from the Danube River

“…In addition, other studies have shown a direct relationship between the high concentrations of PAHs in mussels' tissue and the activation of phase I and phase II biotransformation enzymes (Bebianno et al 2007;Cappello et al 2013). These findings are consistent with previous field studies with bivalves (Fernández et al 2010;Cappello et al 2013) that have reported increased CAT and GST activities in relation to PAH tissue concentrations.…”

A multibiomarker approach in the clam Ruditapes decussatus to assess the impact of pollution in the Ria Formosa lagoon, South Coast of Portugal

“…The present study was undertaken at the middle region of the lagoon, in the most important shellfish bed area within this ecosystem, which accommodates one the major fishing harbours in the South Coast of Portugal. This area is known to be affected by contaminants due to intensive boat traffic and magnitude of fish products in an area of reduced hydrodynamic conditions (Bebianno et al, 2007;Coelho et al, 2002;Cravo et al, 2009;Maria et al, 2009). …”

“…Such an example is the Ria Formosa lagoon, a major coastal lagoon in the Portuguese south coast particularly important for tourism and fish--eries, especially shellfish (Bebianno et al, 2007). The contaminants already known to be present in water, sediments and biota from specific sites of the lagoon include metals (Bebianno, 1995;Bebianno andSerafim, 1998, 2003;Caetano et al, 2002;Cravo et al, 2009;Serafim and Bebianno, 2001), polycyclic aromatic hydrocarbons (PAHs) (Barreira et al, 2007a, b;Bebianno et al, 2007;Bebianno and Barreira, 2009;Cravo et al, 2009), polychlorinated biphenyls (PCBs) (Barreira et al, 2005;Bebianno et al, 2007) and organotin compounds (Coelho et al, 2002;Díez et al, 2005).…”

Biomarkers of damage and protection in Mytilus galloprovincialis cross transplanted in Ria Formosa Lagoon (Portugal)

“…Transplanting molluscs from a reference site to a polluted area should be considered as a feasible strategy for monitoring the effects of environmental changes in coastal or estuarine zones (Da Ros et al 2000;Geffard et al 2007;Bebianno et al 2007). Ria Formosa Lagoon, the largest lagoon on the Portuguese south coast, is an important tourist area being under several pressures that have contributed to the water quality deterioration.…”
