“…oil spills, could be longer in Arctic and sub-Arctic waters compared to warmer regions (AMAP, 1998). Bivalve molluscs, such as blue mussels, are highly affected by oil spills and studies indicate that individuals from pristine environment are more vulnerable to sudden exposure, such as oil spills, compared to individuals from more polluted areas (Albaigés, MoralesNin & Vilas, 2006;Halldórsson, Svavarsson & Granmo, 2005;Stephensen et al, 2000). For animals higher in the trophic level, both seabirds and fur-bearing mammals are vulnerable to oiling as well as small cods that spawn under the ice.…”

“…Studies in the field have mainly utilised a combined approach and linked chemical concentrations to SFG effects in many locations in and around harbours, near sewage outfalls, bays, lagoons and the Irish Sea (Halldórsson et al, 2005;Anderlini, 1992; Widdows et al, 1980 Widdows et al, -81, 1997Widdows et al, and 2002. Clearance rate in mussels has been used as an individual biomarker and in combination with SFG to evaluate the effects of contaminants such as tributyltin and dibutyltin, interactive and individual effects of copper and phenanthrene (Widdows and Page, 1993;Moore et al, 1984) and used on its own to evaluate combined effects of alkanes and aromatic hydrocarbons, complex mixtures of petroleum hydrocarbons and copper, hydrophobic organic toxicants such as naphthalene (Widdows et al, 1989) and mercury chloride (Duchemin et al, 2008).…”

Previous studies have shown that a decline in SFG indicating poor performance and physiological condition was linked to increasing levels of pollution (Widdows et al 1980;2002;Halldórsson et al 2005).…”

Candidate OSPAR/ICES recommended biomarkers at the level of the individual in Mytilus edulis for determination of good environmental status for MSFD were evaluated against contaminant levels at sites around Ireland. The sites chosen ranged from moderate to low pollution levels, but the actual ranking of the sites varied according to the contaminant levels present. At the most contaminated site, Cork, 4 out of 16 contaminants exceeded the EAC, while at Shannon, no EACs were exceeded. The SOS assay suggested that Cork was the healthiest site with a LT 50 of 17.6 days, while SOS for Shannon was 15.6 days. Likewise, condition factors varied among sites and did not always correspond to contaminant-based status. There may be uncertainty in assigning status around the not good:good boundary. This raises potential difficulties not only in the biomarker/contaminant load relationship but also in the reliability of the biomarkers themselves and hence barriers meeting compliance levels.Keywords: OSPAR; ICES; MSFD compliance; Mytilus edulis; Biomarkers; contaminants; IntroductionThe main objective of the Marine Strategy Framework Directive (MSFD) [2008/56/EC] is to maintain good environmental status for marine waters, habitats and resources delivered in an integrated ecosystem based approach. In general current water quality assessments for hazardous substances in Ireland and elsewhere relied solely on chemical analysis alone but it is widely accepted through the Oslo and Paris Commission (OSPAR) and the International Council for Exploration of the Sea (ICES) that chemical monitoring alone is no longer sufficient to assess pollution impacts in the marine environment and that integration of chemical and biological effects data is essential to provide an insight into the actual health status of the ecosystem. In recent years OSPAR and ICES have increased their focus on the integration of biological and chemical data, this being a key reporting requirement under the MSFD (8.2). Integration of such measurements forms an important element in linking contaminants and ecological responses and in assessing the overall quality of the marine environment. Over the last few years a wide range of biomarkers have been employed in monitoring to provide early warning signals for potential contamination.The blue mussel, Mytilus edulis has been extensively used as an indicator of environmental pollution due to its sedentary and filterfeeding nature and its ability to accumulate chemical contaminants from the seawater, from resuspended sediment, and from particulate food material (Moore et al., 2004). The Mussel watch concept, first proposed by Goldberg (1975) has been adopted by many countries including Ireland whereby mussels are used as sentinel organisms of contaminant exposure. As well as contaminant detection in tissues, a range of biomarkers can be used in order to assess impacts on the individual mussel. As part of the ecosystem based approach, an integrated assessment strategy for mussels (Thain et al., 2008) has been put for...

Equilateral venus, Gomphina veneriformis exposed to tribultyltin chloride (TBTCl) for 36 weeks was showed ultrastructural changes of the mantle. The fine mantle had 4-folds and its epidermal layer consisted of simple columnar epithelial cells and ciliated cells and secretory cells. Inner and outer epidermal layer covered connective tissue. The mantle exposed to TBTCl at 12 weeks was decreased cilia in the inner epidermal layer, and observed extension of the hemolymph sinus and destruction of the septum. At 20 weeks, it revealed vacuole formation and pycnosis in the cytoplasm, and scattered muscular fiber. After 28 weeks of exposure, the mantle revealed partially degenerative changes in the epidermal layer. In the ciliated cells, basal body was isolated from the cilia and rootlet complex and basal foot were scattered. The sarcolemma had debris fiber. At 36 weeks, it observed degenerative cells that it revealed disappearance of the cilia, atrophic nucleus, poorly membrane and destruction of the cresternae in the mitochondria, and increasing heterophagosome. The outer epithelial cell had necrotic nuclus, numeous lysosome and disappearance of the microvilli. Therefore, results of this study suggested that chronical TBTCl exposure in the Gomphina veneriformis induced the disorders of shell growth and physiological function with histopathological changes of the mantle.
