“…In the specific case of the Prestige, after 5 months the spill an increase in oxidative stress, as evaluated by means of enzyme determinations (EROD, GST, GR and CAT), was detected in the demersal fish species Lepidorhombus boscii and Callionymus lyra, gradually decreasing in the 3 years after the spill (Martí-nez-Gómez et al 2006. Similarly, Cajaraville et al (2006) and found a high degree of disturbance in several cell and tissue biomarkers (peroxisome proliferation, lysosomal membrane stability, atrophy of digestive epithelium, acyl-CoA oxidase-AOX Table 6 Mean values (±standard error,) of physiological components of the energy balance of wild mussels under standardized laboratory conditions (15°C, filtered seawater at 35 ppm, ; 2 J h -1 for a standarized individual of 1 g of meat dry weight Data with the same superscript indicated that they did not differ significantly at the 95% level (SNK test done after a significant ANOVA was performed at each site) CR clearance rate, IR ingestion rate, AR absorption rate, ER excretion rate, RR respiration rate, SFG scope for growth Fig. 3 Components of the energy budget of wild mussels collected from Galician coast sites affected by the Prestige oil spill.…”

The aim of this study was to assess environmental quality at some of the sites most severely affected by the Prestige oil spill off 2 years after the spillage (April and November 2004). For this purpose analyses of polycyclic aromatic hydrocarbons (PAH) and several biochemical (antioxidant enzymes catalase, glutathione reductase, glutathione peroxidase, superoxide dismutase and DT-diaphorase and lipid peroxidation) and physiological [scope for growth (SFG)] biomarkers were determined on wild mussel populations (Mytilus galloprovincialis) collected at four points along the Costa da Morte and compared with those of a reference site not affected by the oil spill. Results showed that PAH contents had markedly decreased 17 months after the accident, although they were higher in April than in November, when they showed values similar to background levels reported for this area. Nevertheless, the predominance of chrysene on PAH profiles, similarly to findings obtained immediately after the spill, indicated the Prestige as their main source. In spite of the low PAH levels recorded, antioxidant activity levels (explained through the integrated antioxidant response-IAR) were higher in the Costa da Morte than at the reference site either in April and November. In April IAR seems to be related to PAH levels found 3 months after the accident (February 2003), suggesting the persistence in the environment of oxidative stress-producing components from the spill. However, evidence of oxidative stress was not reflected at physiological level by scope for growth, with only very slight differences being observed between values from the reference site and those from Costa da Morte sites. In conclusion, although 2 years after the spill PAHs bioaccumulated by mussels from the Costa da Morte had decreased to background levels, biochemical parameters showed signals of oxidative stress in mussels from this area. However, SFG reflected a good health status for the mussel populations studied and did not reveal evidence of physiological disturbance either 17 or 24 months after the Prestige spill.

“…Soriano et al (2006) also reported that the concentration was above 1,000 to 7,780 μg/kg dry weight in M. galloprovincialis Concentration (ng/g dry) at sites most affected by the Prestige oil spill after 2-3 months. In the Prestige oil spill, several effects on shellfish and other aquatic organisms were reported (Cajaraville et al 2006;Laffon et al 2006;Pérez-Cadahía et al 2004). Although those concentrations were slightly higher than those in the Solar I oil spill, it could be anticipated that shellfish could be affected by heavy pollution of the spilled oil from Solar I.…”

Following the oil spill accident of the Solar I tanker in 2006 off the coast of Guimaras Island in the Philippines, polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs in some aquatic organisms were investigated at Luzaran in Guimaras and Taklong Islands, which were heavily polluted with spilled oil, immediately and 1 month after the accident. The concentrations of total PAHs were 11.9-52.3 ng/g dry weight in fish. Meanwhile, total PAH concentrations in shellfish were 38.0-3,102 ng/g dry weight in Luzaran and 128-236 ng/g dry weight in Taklong. Pyrene, phenanthrene, and fluoranthene were dominant in most fish and chrysene in all shellfish. Significantly higher concentrations of all alkylated homologs were detected in shellfish than in fish. These differences had two possible causes, that is, the differences between fish and shellfish could be attributed to the uptake routes and/or their metabolizing abilities.

“…For these purposes, the five aforementioned approaches were applied to provide an uncomplicated integrative view of the degree and duration of the POS effects assessed through biomarkers in sentinel mussels, Mytilus galloprovincialis collected in 22 localities along the North coast of the Iberian Peninsula over 3 years (April 2003–April 2006; Marigómez et al 2006; Orbea et al 2006; Cajaraville et al 2006; Ortiz-Zarragoitia et al 2011; Garmendia et al 2011a, b, c). The Prestige tanker carrying 77,000 tonnes of heavy fuel–oil sunk in NW Iberian coast in November 2002.…”

Marine ecosystem health status assessment through integrative biomarker indices: a comparative study after the Prestige oil spill “Mussel Watch”

Five integrative biomarker indices are compared: Bioeffects Assessment Index (BAI), Health Status Index (HSI), integrated biological response (IBR), ecosystem health condition chart (EHCC) and Integrative Biomarker Index (IBI). They were calculated on the basis of selected biomarker data collected in the framework of the Prestige oil spill (POS) Mussel Watch monitoring (2003–2006) carried out in Galicia and the Bay of Biscay. According to the BAI, the health status of mussels was severely affected by POS and signals of recovery were evidenced in Galicia after April-04 and in Biscay Bay after April-05. The HSI (computed by an expert system) revealed high levels of environmental stress in 2003 and a recovery trend from April-04 to April-05. In July-05, the health status of mussels worsened but in October-05 and April-06 healthy condition was again recorded in almost all localities. IBR/n and IBI indicated that mussel health was severely affected in 2003 and improved from 2004 onwards. EHCC reflected a deleterious environmental condition in 2003 and a recovery trend after April-04, although a healthy ecosystem condition was not achieved in April-06 yet. Whereas BAI and HSI provide a basic indication of the ecosystem health status, star plots accompanying IBR/n and IBI provide complementary information concerning the mechanisms of biological response to environmental insult. Overall, although the integrative indices based on biomarkers show different sensitivity, resolution and informative output, all of them provide coherent information, useful to simplify the interpretation of biological effects of pollution in marine pollution monitoring. Each others’ advantages, disadvantages and applicability for ecosystem health assessment are discussed.
