“…Thus, although occasionally the eventual occurrence of parasites may act as a confounding factor, in general terms only 2 different periods are distinguished throughout an annual cycle: from late March to early June (reproductive stress) and from late June to early March. Consequently, considering the low signal and responsiveness of biomarkers in winter (Marigómez et al 1996, Etxeberria et al 1994, Orbea et al 2002, Izagirre et al 2008 together with the present results regarding seasonal trends, we recommend that for long-term biomarker-based pollution monitoring with sentinel mussels in the North Iberian Peninsula, organisms are sampled twice per year, once in the spring period (March-June) and once during autumn, as in the Mediterranean Sea (Zorita et al 2007). …”

Mussels Mytilus galloprovincialis were collected monthly in 2 localities in the Northern Iberian Peninsula, Oia (Galicia) and Mundaka (Basque Coast), from April 2005 to May 2006, to investigate whether seasonal variability in biomarkers follows the same pattern at both geographical areas. The following battery of biomarkers was analysed: lysosomal membrane stability and structural changes, intracellular neutral lipid accumulation, cell type composition in the digestive gland epithelium, structural changes of digestive alveoli and digestive gland histopathology. Additionally, gonad index was measured as a supporting parameter. Overall, results demonstrate that most studied biomarkers showed similar seasonal variability pattern in both localities. Lysosomal membrane stability (labilisation period [LP]) and most histopathological conditions showed similar seasonal variability patterns in both localities, although values of LP and prevalences of some parasites were higher in Mundaka. Data provide baseline values to be used as reference values for the biomonitoring programmes carried out in coastal areas from Galicia to the Basque Coast. It is concluded that for monitoring programmes based on biomarkers, samples must be taken at least twice per year (spring and autumn) to avoid the effect on biomarkers of the late stages of each reproductive cycle.

“…Therefore, to overcome this drawback and integrate the data as a whole, a PCA was conducted. In ecosystems like the Ria Formosa lagoon, where contamination is not particularly high, seasonal factors such as severe environmental parameters (Table 2) have an important effect on biomarkers response (Leiniö and Lehtonen, 2005;Orbea et al, 2002), as reflected by the correlation between biomarkers and environmental conditions for the global studied period (Fig. 2).…”

“…Nevertheless, the mean total PAHs concentration in the impacted samples exceeded the TEL and ERL, suggesting potential toxicological effects of chronic exposure. Under acute exposure, sublethal endpoints such as antioxidant enzymatic activities are considered as relevant indicators of PAHs pollution in marine organisms (Orbea et al 2002;De Luca-Abbott et al 2005;Sureda et al 2011;Bebianno et al 2015). These 'non-specific' biomarkers have frequently been used for environmental monitoring assessments sometimes with results that are difficult to interpret (Vlahogianni et al, 2007;Valavanidis et al 2006;Brooks et al 2013;Nahrgang et al 2013).…”

Recent offshore petroleum exploration has increased the risks of oil spills worldwide. We investigated biomarker responses to diesel oil exposure in two tropical and subtropical species, the clam Anomalocardia flexuosa and the polychaete Laeonereis culveri. Animals were exposed to oil-spiked sediment at two different concentrations (0.5 L m -2 and 1.0 L m -2 ). Activities of antioxidant enzymes catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx); glutathione transferase (GST), and lipid peroxides (LPO) were assessed in bivalve digestive glands and polychaete whole-body homogenates at 36 h and 60 h of exposure.Significant variation in enzymatic antioxidant activity depended on the sampling time after exposure. No similar response patterns, either increases or decreases, were detected for the two target species, and biomarker responses were species-specific. L. culveri showed clearer patterns in its antioxidant response and should be prioritized over other species in biomonitoring studies involving oil exposure. Understanding the temporal variability of these biomarkers is a necessary action before implementing them as indicators measures in oil contamination biomonitoring programs. Our results provide a better understanding of biomarker responses in subtropical species, evidencing their potential use as sentinels of oil contamination.
