A large scale survey of trace metal levels in coastal waters of the Western Mediterranean basin using caged mussels (Mytilus galloprovincialis) ArchiMer
Benedicto, Jose; Andral, Bruno; Martinez-gomez, Concepcion; Guitart, Carlos; Deudero, Salud; Cento, Alessandro; Scarpato, Alfonso; Caixach, Josep; Benbrahim, Samir; Chouba, Lassaad; Boulahdid, Mostefa; Galgani, Francois.
A large scale study of trace metal contamination (Hg, Cd, Pb and Ni) by means of caged mussels Mytilus galloprovincialis was undertaken along the coastal waters of the Western Mediterranean Sea within the context of the MYTILOS project. Individual mussels from an homogeneous population (shell size 50 +/- 5 mm) obtained from an aquaculture farm were consecutively caged and deployed at 123 sites located in the Alboran, North-Western, South-Western and Tyrrhenian sub-basins for 12 weeks (April-July) in 2004, 2005 and 2006. After cage recoveries, both the metal content in the whole mussel tissue and the allometric parameters were measured. Statistical analysis of the datasets showed significant differences in concentrations between sub-basins for some metals...

Assessment of contaminant concentrations in sediments, fish and mussels sampled from the North Atlantic and European regional seas within the ICON project ArchiMer
Robinson, Craig D.; Webster, Lynda; Martinez-gomez, Concepcion; Burgeot, Thierry; Gubbins, Matthew J.; Thain, John E.; Vethaak, A. Dick; Mcintosh, Alistair D.; Hylland, Ketil.
Understanding the status of contaminants in the marine environment is a requirement of European Union Directives and the Regional Seas Conventions, so that measures to reduce pollution can be identified and their efficacy assessed. The international ICON workshop (Hylland et al., in this issue) was developed in order to test an integrated approach to assessing both contaminant concentrations and their effects. This paper describes and assesses the concentrations of trace metals, polycyclic aromatic hydrocarbons, and polychlorinated biphenyls in sediments, mussels, and fish collected from estuarine, coastal and offshore waters from Iceland to the Mediterranean Sea. For organic contaminants, concentrations progressively increased from Iceland, to the...

How can we quantify impacts of contaminants in marine ecosystems? The ICON project ArchiMer
Hylland, Ketil; Burgeot, Thierry; Martinez-gomez, Concepcion; Lang, Thomas; Robinson, Craig D.; Svavarsson, Jorundur; Thain, John E.; Vethaak, A. Dick; Gubbins, Matthew J..
An international workshop on marine integrated contaminant monitoring (ICON) was organised to test a framework on integrated environmental assessment and simultaneously assess the status of selected European marine areas. Biota and sediment were sampled in selected estuarine, inshore and offshore locations encompassing marine habitats from Iceland to the Spanish Mediterranean. The outcome of the ICON project is reported in this special issue as method-oriented papers addressing chemical analyses, PAH metabolites, oxidative stress, biotransformation, lysosomal membrane stability, genotoxicity, disease in fish, and sediment assessment, as well as papers assessing specific areas. This paper provides a background and introduction to the ICON project, by...

Integrated chemical and biological assessment of contaminant impacts in selected european coastal and offshore marine areas ArchiMer
Hylland, Ketil; Robinson, Craig D.; Burgeot, Thierry; Martinez-gomez, Concepcion; Lang, Thomas; Svavarsson, Jorundur; Thain, John E.; Vethaak, A. Dick; Gubbins, Mattew J..
This paper reports a full assessment of results from ICON, an international workshop on marine integrated contaminant monitoring, encompassing different matrices (sediment, fish, mussels, gastropods), areas (Iceland, North Sea, Baltic, Wadden Sea, Seine estuary and the western Mediterranean) and endpoints (chemical analyses, biological effects). ICON has demonstrated the use of a framework for integrated contaminant assessment on European coastal and offshore areas. The assessment showed that chemical contamination did not always correspond with biological effects, indicating that both are required. The framework can be used to develop assessments for EU directives. If a 95% target were to be used as a regional indicator of MSFD GES, Iceland and offshore...

Integrated indicator framework and methodology for monitoring and assessment of hazardous substances and their effects in the marine environment ArchiMer
Vethaak, A. Dick; Davies, Ian M.; Thain, John E.; Gubbins, Matthew J.; Martinez-gomez, Concepcion; Robinson, Craig D.; Moffat, Colin F.; Burgeot, Thierry; Maes, Thomas; Wosniok, Werner; Giltrap, Michelle; Lang, Thomas; Hylland, Ketil.
Many maritime countries in Europe have implemented marine environmental monitoring programmes which include the measurement of chemical contaminants and related biological effects. How best to integrate data obtained in these two types of monitoring into meaningful assessments has been the subject of recent efforts by the International Council for Exploration of the Sea (ICES) Expert Groups. Work within these groups has concentrated on defining a core set of chemical and biological endpoints that can be used across maritime areas, defining confounding factors, supporting parameters and protocols for measurement. The framework comprised markers for concentrations of, exposure to and effects from, contaminants. Most importantly, assessment criteria for...

Integrated monitoring of chemicals and their effects on four sentinel species, Limanda limanda, Platichthys flesus, Nucella lapillus and Mytilus sp, in Seine Bay: A key step towards applying biological effects to monitoring ArchiMer

The International workshop on Integrated Assessment of CONtaminants impacts on the North sea (ICON) provided a framework to validate the application of chemical and biological interpretation thresholds (BACs and EACs) in the Seine Bay in France. Bioassays (oyster larval anomalies, Corophium arenarium toxicity assay and DR Calux) for sediment and biomarkers: ethoxyresorufin-O-deethylase (EROD) activity, acetylcholinesterase (AChE) activity, lysosomal membrane stability (LMS), DNA strand breaks using the comet assay, DNA adducts, micronucleus (MN), PAH metabolites, intersex and fish external pathologies were analyzed in four marine sentinel species (Platichthys flesus, Limanda limanda, Mytilus sp. and Nucella lapilus). Polycyclic aromatic hydrocarbons...
