| The oyster culture basin of Marennes - Oléron is characterized by the tastiness of its oysters and the good quality of its waters, and thus of its shellfish. On that account, the quasi-totality of the production areas are ranked A for non-burrowing shellfishes, thus confirming the privileged character of the basin. This microbiological and chemical quality contributing to the reputation of the basin's shellfish farms needs to be preserved. In this purpose, the Regional Shellfish Culture Section of Marennes - Oléron (SRC) approached the Ifremer in order to continue the monitoring of the microbiological quality carried out on different production areas susceptible to be affected by some bacteriological contaminations leading to a deterioration of the... |

| Objective. Ostreopsis ovata and Ostreopsis siamensis are tropical unicellular algae that have been found recently in the Mediterranean. Both of these dinoflagellates produce palytoxin (PTX)-like toxins that are powerful vasoconstrictors in mammals. Since 2003, Ostreopsis blooms in Italy and Spain have been accompanied by reports of respiratory problems and skin/mucosa irritation in persons in contact with toxic microalgal cells (epiphytes, plankton, or sea spray) or associated toxins. Methods. In France, a surveillance network has been set up to monitor water conditions and to protect swimmers from contamination due to Ostreopsis. Results. Between 2006 and 2009, a total of nine blooms were observed on the French Mediterranean coast including five that led... |

| A coastal river 380 km long, the Charente river has a catchment area of about 10,000 km2, flowing through the departments of Charente and Charente-Maritime, as well as a small part of the border departments: Dordogne, Deux-Sèvres, Haute-Vienne and Vienne. Its main affluents are the Tardoire, the Seugne and the Boutonne rivers. The highest part of the catchment area is located in Dordogne, at a height of 496 m, whereas the river itself originates from a spring located at a height of 250 m to the south-east of Rochechouart, in the Haute-Vienne. The average height of the catchment area is quite low. In its downstream part, from the Saint-Savinien dam to the ocean, the Charente is influenced by a dynamic tide. The actual estuarine part begins in... |

| An initial surveillance system of Ostreopsis ovata was set Lip along the Mediterranean coast in the summer of 2007. To Strengthen and adapt this system, we reviewed the information available for a health risk assessment of this monocellular species of algae that produces palytoxin and is increasingly observed in the Mediterranean Sea. Since 2002, this species has been reported to be responsible for many human cases of irritation, Cough, fever and respiratory problems in Europe. It is not Currently possible to determine if palytoxin causes these health effects, which follow aerosol inhalation. Ingestion of contaminated seafood may lead to very serious poisoning, but no such case has yet been described in Europe. A "dose-response' relation cannot be... |

| Cette étude, qui a rassemblé les compétences des instances de l'Etat chargées de la surveillance du milieu littoral (DDE, DDASS, IFREMER, Université de La Rochelle) a permis de dresser, à la veille de l'an 2000, un bilan de la situation environnementale du littoral de la « mer des Pertuis». Ce bilan, diversifié dans sa présentation, passe en revue les points marquants de "l'état de santé" de l'environnement, qu'il s'agisse de pollutions ciblées (chimiques, bactériologiques) ou d'autres nuisances variées. Il met en exergue les points forts et les points faibles en matière d'environnement littoral, et rappelle les efforts mis en oeuvre par les différentes administrations chargées de sa surveillance. Dans un premier temps, plus de 250 références... |

| Le Laboratoire Côtier de La Tremblade est implanté géographiquement dans le premier bassin ostréicole d'Europe (30 000 tonnes produites et 60 000 tonnes commercialisées chaque année). L'ostréiculture est une activité économique très importante en terme d'emplis, qui doit cohabiter sur un même littoral avec le tourisme et l'agriculture générant parfois des conflits d'usages (gestion de l'eau, qualité de l'eau). Les avis donnés à l'Administration ou aux collectivités locales s'appuient sur les résultats de la surveillance ou ceux émanant des études spécifiques comme les études microbiologiques locales. Les activités, les responsabilités de chacun dans le cadre ce de mandat, figurent dans le Manuel Qualité du Laboratoire. Enfin, l'assistance technique à la... |

| The microbiological classification of the Marennes-Oléron shellfish farming area (according to Council Directive 91/492/EEC) let appear sorne periodically polluted spots. A research of the potentiel sources has been conducted around these spots. Twelve points were sampled during a year with faecal coliforms and streptococcus contamination level in water (and shellfich when possible). Several microbiological pollution sources were found, in the Seudre estuary (umstream) and in Oléron island : lack of, or ineffective sewage systems, cattle farming without convenient manure treatrrtent, and so on .. Recommendations are given to improve this situation. |

| Dans le cadre de la contractualisation Ifremer / SRC intitulée « Actions de l'Ifremer au profit de la Section Régionale Conchylicole de Marennes-Oléron (année 2001) », l'action 3 prévoit le suivi de la reproduction de la moule (Mytilus edulis) et de l'huître (Crassostrea gigas) dans le bassin de Marennes-Oléron. Son but est triple : ~ détecter les émissions larvaires, ~ suivre dans le temps le devenir des cohortes de larves, ~ permettre la fourniture des informations aux professionnels. Pendant la saison 2001, des pêches de larves de moules ont été réalisées au point <<Boyard», à la demande des mytiliculteurs. En outre, afin d'informer les ostréiculteurs, des pêches de larves d'huîtres ont été effectuées aux points « Coux », « les Faulx », « les... |

| The monitoring of the reproduction of Crassostrea gigas, and more occasionally that of the mussel Mytilus edulis, is carried out in the Marennes-Oléron Basin, each year, from June through to September. This report presents the main results obtained in 1997, 1998, 1999, 2000 and compares them. It also recalls the techniques used and provides, in appendix, some bibliographic information on larval development. |

| The accumulation of trace metals (Cd, Co, Cr, Hg, Ni and Pb) was measured in water, sediment, the mussel Mytilus galloprovincialis and the seagrass Posidonia oceanica. Samples were collected in three locations of the north-western Mediterranean (Canari, Livorno and Porto-Torres) which present different levels and sources of human impact. Analyses in the different compartments (water, sediment, M. galloprovincialis and P. oceanica) have allowed to identify Canari as the most Cd, Co, Cr and Ni contaminated site; Livorno as the most Hg contaminated and Porto-Torres as the most Pb contaminated. Furthermore, for the first time, metal concentrations found in P. oceanica have been compared with those found in the water column, in the sediment and in the... |

| This report presents recent data on chemical contaminants in coastal and transition water bodies of Adour-Garonne district, acquired as part of the WFD (water measurements in 2009) and network ROCCH (measures in sediments in 1999 and 2008 and in shellfish each year between 2008 and 2010). It should be noted that only environmental quality standards exist for water, and in the absence of sediment and biota EQS, it is not possible to use these data to determine the chemical quality of water bodies. However, when other types of reference values are available (produced by OSPAR for example), they are used to argue the status of water bodies in support of the data obtained on the water under the control WFD monitoring. |
