Marine Strategy Framework Directive. task group 8 : report contaminants and pollution effects

The Marine Strategy Framework Directive (2008/56/EC) (MSFD) requires that the European Commission (by 15 July 2010) should lay down criteria and methodological standards to allow consistency in approach in evaluating the extent to which Good Environmental Status (GES) is being achieved. ICES and JRC were contracted to provide scientific support for the Commission in meeting this obligation. A total of 10 reports have been prepared relating to the descriptors of GES listed in Annex I of the Directive. Eight reports have been prepared by groups of independent experts coordinated by JRC and ICES in response to this contract. In addition, reports for two descriptors (Contaminants in fish and other seafood and Marine Litter) were written by expert groups coordinated by DG SANCO and IFREMER respectively. A Task Group was established for each of the qualitative Descriptors. Each Task Group consisted of selected experts providing experience related to the four marine regions (the Baltic Sea, the North-east Atlantic, the Mediterranean Sea and the Black Sea) and an appropriate scope of relevant scientific expertise. Observers from the Regional Seas Conventions were also invited to each Task Group to help ensure the inclusion of relevant work by those Conventions. This is the report of Task Group 8 Contaminants and pollution effects.

Directive cadre sur l’eau - Bassin Loire-Bretagne. Contrôle de surveillance dans les masses d’eau côtières et de transition. Actions menées par Ifremer en 2014

Le contrôle de surveillance 2014 pour la DCE appliquée dans les eaux littorales de Loire Bretagne a porté sur les 25 masses d’eau côtières (sur 39 au total) et les 16 masses d’eau de transition (sur 30 au total) retenues au titre du contrôle de surveillance. L’ensemble des résultats acquis, aussi bien sur les paramètres biologiques que chimiques, a permis de mettre à jour l’évaluation de l’état des masses d’eau affiché sur l’atlas DCE accessible sur la page web d’Envlit correspondante.

Determination of thresholds in marine molluscs as an alternative to the Environmental Quality Standards in marine water defined in the Water Framework Directive

The Water Framework Directive (WFD) establishes Environmental Quality Standards (EQS) in marine water for 34 priority substances. Among these substances, 25 are hydrophobic and bioaccumulable (2 metals and 23 organic compounds). For these 25 substances, monitoring in water matrix is not appropriate and an alternative matrix should be developed. Bivalve mollusks, particularly mussels (Mytilus edulis, Mytilus galloprovincialis), are used by Ifremer as a quantitative biological indicator since 1979 in France, to assess the marine water quality. This study has been carried out in order to determine thresholds in mussels at least as protective as EQS in marine water laid down by the WFD. Three steps are defined: - Provide an overview of knowledges about the relations between the concentrations of contaminants in the marine water and mussels through bioaccumulation factor (BAF) and bioconcentration factor (BCF). This allows to examine how a BCF or a BAF can be determined: BCF can be determined experimentally (according to US EPA or ASTM standards), or by Quantitative Activity-Structure Relationship models (QSAR): four equations can be used for mussels. BAF can be determined by field experiment; but none standards exists. It could be determined by using QSAR but this method is considered as invalid for mussels, or by using existing model: Dynamic Budget Model, but this is complex to use. - Collect concentrations data in marine water (Cwater) in bibliography for those 25 substances; and compare them with concentration in mussels (Cmussels) obtained through French monitoring network of chemicals contaminants (ROCCH) and biological integrator network RINBIO. According to available data, this leads to determine the BAF or the BCF (Cmussels /Cwater) with field data. - Compare BAF and BCF values (when available) obtained with various methods for these substances: BCF (stemming from the bibliography, using experimental process), BCF calculated by QSAR and BAF determined using field data. This study points out that experimental BCF data are available for 3 substances (Chlorpyrifos, HCH, Pentachlorobenzene). BCF by QSAR can be calculated for 20 substances. The use of field data allows to evaluate 4 BAF for organic compounds and 2 BAF for metals. Using these BAF or BCF value, thresholds in shellfish can be determined as an alternative to EQS in marine water.

Mise en oeuvre de la surveillance pour la Directive Cadre Européenne sur l’Eau dans les départements d’Outre-Mer - Volet littoral

The implementation of the WFD in the French overseas takes into account local, morphological, climatic and socioeconomic peculiarities, as well as specificities of their ecosystems. This document provide an up-to-date assessment of the state of characteristics of the coastal water bodies, of development of indicators and of WFD monitoring programs in each of the French overseas departments: Martinique, Guadeloupe, French Guyana, Reunion Island and Mayotte.

Directive Cadre sur l’Eau : les pressions anthropiques et leur impact sur les indicateurs de l’état écologique des masses d’eau littorales de la façade Manche-Atlantique. Synthèse bibliographique

Within the European water framework directive (WFD), the status assessment of littoral waters is based both on the chemical quality and on the ecological quality of each water body. Quality elements enabling to assess the ecological status of a water body are, among other things, biological quality elements (phytoplankton, macroalgae, angiosperms, benthic invertebrates, fish), for each of which the member states have developed quantitative indicators. This document is one of the deliverables of a multi-annual study intended to characterize the sensitivity of these biological indicators towards the various anthropogenic pressures exerted on the French Atlantic and Channel coast: ultimately, the goal is to establish a quantitative and predictive relationship, statistically robust, between the WFD indicators used along the French channel and Atlantic coastline, and various anthropogenic pressures acting on these coasts. The aim of the WFD is indeed to restore or maintain a good chemical and biological quality of coastal waters, and thus to limit the impact of human activities potentially responsible for the degradation of ecosystems. This understanding of the linkages and interactions existing between anthropogenic pressures and ecological status of water bodies is therefore essential to identify priorities for action (challenges, substances ...), prioritize actions to implement within restoration programs (technical, fiscal, financial), but also to be able to communicate constructively and persuasively in talks between managers and the various stakeholders of coastal regions. Using the DPSIR methodology, this literature analysis has permitted to identify, for each WFD biological quality element (except fish), which pressures (or pressure types) are potentially relevant in the light of their impact on the indicators of the ecological status of water bodies. Some metrics and indicators of anthropogenic pressures used in the literature to characterize the sensitivity of the biological quality elements, within quantitative approaches, were also identified. It is also clear from this review that the biological quality elements can be particularly sensitive to intrinsic environmental conditions, and therefore to certain changes related to natural phenomena occurring at large scales (e.g. climate change, paroxysmal climate episode...). Therefore, when one is interested in the sensitivity of biological indicators to different anthropogenic pressures, two factors can complicate the analysis and are likely to weaken the resulting statistical relationships: on the one hand, the variability of biological responses depending on the natural context and, on the other hand, interactions (so called synergistic effects) between different types of anthropogenic pressures and the alterations they can generate.

Directive Cadre sur l’Eau : les pressions anthropiques et leur impact sur les indicateurs de l’état écologique des masses d’eau littorales de la façade Manche-Atlantique - Développement d’une base de données quantitatives sur les pressions anthropiques littorales

Within the European water framework directive (WFD), the status assessment of littoral waters is based both on the chemical quality and on the ecological quality of each water body. Quality elements enabling to assess the ecological status of a water body are, among other things, biological quality elements (phytoplankton, macroalgae, angiosperms, benthic invertebrates, fish), for each of which member states have developed quantitative indicators. This document compiles three deliverables of a multi-annual study intended to characterize the sensitivity of these biological indicators regarding the various anthropogenic pressures exerted on the French Atlantic and Channel coast: ultimately, the goal is to establish a quantitative and predictive relationship, statistically robust, between the WFD indicators used along the French channel and Atlantic coastline, and various anthropogenic pressures acting on these coasts. These three deliverables are the following : - The reports of various interviews performed with French national referents for the biological quality elements used within the littoral part of the WFD in Channel and Atlantic (phytoplankton, subtidal and intertidal macroalgae, opportunistic blooming macroalgae, angiosperms and benthic invertebrates). These interviews aimed to specify, for each metric constitutive of the BQE indicator (if multi-metric), the "relevant" pressures, as well as the trend of this impact, - Sheets describing the "pressure" and "environment" data available, in order to characterize spatially and quantitatively these "relevant" anthropogenic pressures acting on French Channel and Atlantic coast, - A progress report dealing with the development of a database tool, for archiving quantitative data characterizing "relevant" littoral anthropogenic pressures.
