A pollution-monitoring pilot study involving contaminant and biomarker measurements in the Seine Estuary, France, using zebra mussels (Dreissena polymorpha) ArchiMer
Minier, Christophe; Abarnou, Alain; Jaouen Madoulet, Agnes; Le Guellec, Anne-marie; Tutundjian, Renaud; Bocquene, Gilles; Leboulenger, François.
Zebra mussel (Dreissena polymorpha) is an invasive species that has proliferated in European and North American rivers and lakes during the last century. In this study, D. polymorpha has been used to provide information on contamination levels and biological effects in the Seine Estuary (France). The bivalves accumulated polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) to a high degree with values reaching 800 ng/g dry weight for PCBs (sum of 20 congeners), and 1,000 ng/g dry weight of PAHs (sum of 14 compounds) in the whole body. These values are among the highest reported of PCBs and, to a lesser extent, of PAHs in other contaminated areas in the world. Toxic equivalent quantities of PCBs and PAHs detected in zebra mussels...

Chlordecone in the marine environment around the French West Indies: from measurement to pollution management decisions ArchiMer
Bertrand, Jacques; Bodiguel, Xavier; Abarnou, Alain; Reynal, Lionel; Bocquene, Gilles.
Chlordecone is a very persistent insecticide used in banana plantations of the French West Indies between 1972 and 1993. Chlordecone residues were found in inland water, in agricultural and freshwater products, and in marine organisms. This pollution has become of great concern in 2007. Therefore, a governmental action Plan was launched to better assess the pollution and to improve the consumer’s protection. Within this plan, 1048 samples from 69 different species of marine fishes and crustaceans were collected all around both the Guadeloupe and the Martinique Islands and analyzed. The results confirm the presence of chlordecone in marine organisms, with highly variable concentrations (from the detection limit to 1000 μg.kg-1). In 17.9 % of the samples,...

Compte-rendu et recommandations de l'atelier RINBIO tenu au Centre de Nantes les 19 et 20 janvier 1997 - De l'usage de la méthode des transplants de moule pour le suivi de la contamination chimique le long des côtes méditerranéennes françaises ArchiMer
Cossa, Daniel; Abarnou, Alain; Andral, Bruno; Bougrier, Serge; Buestel, Dominique; Claisse, Didier; Hatt, Philippe-jacques; Stanisiere, Jean-yves.
Ce rapport fait suite à la création par les directions DEL et DRV de l'IFREMER d'un groupe de travail, dit RlNBIO, chargé d'étudier les implications de l'usage des transplants de populations de moules pour évaluer la contamination chimiques des zones côtières méditerranéennes. L'objectif du Réseau Intégrateurs Biologiques (RlNBIO) est en effet d'obtenir une évaluation des niveaux de la contamination chimique à l'échelle du bassin méditerranéen français. La méthodologie s'appuie sur la mesure des concentrations en contaminants métalliques et organiques bioaccumulés dans les tissus de moules transplantées (Mytilus galloprovincialis) pendant plusieurs dans les zones à étudier. Or, la phase exploratoire a mis en évidence une interdépendance entre les niveaux...

Contamination chimique du milieu marin : de la mesure à l'évaluation des risques ArchiMer
Abarnou, Alain.
This activity report entitled (“Chemical contamination of the marine environment: from measurement to risk assessment”) summarizes the main stages my career at Ifremer from November 1975 to june 2013. The first chapter deals with the seawater chlorination and chlorinated waters released into the sea, the identification and the conditions of the formation of various by-product of these processes. The second chapter concerns PCBs, their nature, their chemical analysis in environmental matrices. PCBs are considered as the best examples of persistant and bioaccumulable compounds and therefore, in all this report they are flagship contaminants to which other groups of studied substances are compared. The third chapter refers to studies performed within marine...

Contamination de l'estuaire et de la baie de Seine par le PCB-Bilan des etudes ArchiMer
Abarnou, Alain; Simon, S.
This report is a synthesis of data concerning PCB concentrations in water, sediments and organisms (Bivalvia, Malacostraca, Pisces). Water analysis shows that Seine River is the primordial factor affecting PCB dispersion in the bay. Sediment contamination is higher near estuary along Calvados coast. PCB levels in Mytilidae and in Pectinidae set the problem of polluant origin, dispersion and effects on estuarine organisms.

Contamination par les organochlorés des dauphins de Commerson des îles Kerguelen ArchiMer
Abarnou, Alain; Robineau, Daniel; Michel, Pierre.
Top predators like marine mammals have been intensively used for monitoring the contamination of the marine environment, particularly in industrialized coastal areas of the Northern Atlantic Ocean. Such data concerning contamination in the Southern hemisphere are very scarce. Samples were taken in the fatty protuberance of the forehead (melon) from eleven Commerson's dolphins (Cephalorhynchus commersonii, Lacépède, 1804) caught in the coastal waters of the Kerguelen Islands (Southern Indian Ocean). They were analyzed for DDT, PCB and HCB, using capillary gaz chromatography. The levels of contamination [DDT= 1 150 ± 650, PCB = 1 150 ± 770, HCB=500±300ng/g of extracted matter (lipids)] are between ten and a hundred times Jess than those found in similar...

Correlations between dioxin-like and indicators PCBs: Potential consequences for environmental studies involving fish or sediment ArchiMer
Babut, M.; Miege, C.; Villeneuve, B.; Abarnou, Alain; Duchemin, J.; Marchand, P.; Narbonne, J. F..
Among the numerous PCB congeners, most of the dioxin-like PCBs (DL-PCBs) need to be characterized by hyphenated techniques. It has been shown in several instances that these congeners are well related to the total PCB content in fish. We examined datasets collected mainly in France, on freshwater and marine fish and sediments. A statistical model linking DL- and indicator PCBs was developed for a dataset composed of freshwater fishes, and proved to predict well DL-PCBs from indicator PCBs in all other fish sets, including marine ones. Type II error rates remained low in almost all fish sets. A similar correlation was observed in sediments. Non-dioxin-like PCBs elicit various adverse effects and represent 95% of the total PCBs. A European guideline for them...

Diagnostic de la contamination chimique de la faune halieutique des littoraux des Antilles françaises. Campagnes 2008 en Martinique et en Guadeloupe ArchiMer
Bertrand, Jacques; Abarnou, Alain; Bocquene, Gilles; Chiffoleau, Jean-francois; Reynal, Lionel.
During the years 1972-1993, kepone a persistent pesticide has been used in the banana fields of the French West Indies (Martinique and Guadeloupe) to content a weevil. A slow desorption of the molecule from soil induces its transfer to the sea through the rivers from leaching and erosion. This study intended to take stock on the contamination by kepone of the fishery species around the islands fifteen years after the kepone ban. Furthermore other chemical pollutants were sought in fish and shellfish around the Martinique island. The results confirmed persistence of marine fauna contamination by kepone, mainly in the alluvium areas in front of polluted rivers. They shown also that this contamination may spread more widely but with fast decreasing through...

Distribution et devenir de contaminants persistants dans les écosystèmes littoraux. Comparaison Manche ouest-Manche est ArchiMer
Abarnou, Alain; Duchemin, Jean.
This study on the "distribution and future of persistent contaminants in coastal ecosystems, comparison between the western Channel and the eastern Channel" was carried out by the Ifremer for the Water Agency of Seine-Normandie. It provides information on the level of relatively well-known and regulated contaminants (cadmium, mercury, lead, BPC, dioxins, PAH) in sea products, as well as on that of less systematically recorded substances (silver, copper, nickel, zinc, polybrominated biphenyls, ethers, alkylphenols, phtalats). The Lower-Norman coast, from the Seine estuary and the Mont Saint-Michel, is particularly interesting for this study since this limited geographic area is home to the most extreme levels of contamination recorded along the entire...

Port activities require continuous or occasional dredging of considerable quantities of sediments : approximately 50 million m3 along the French coastline. A large proportion of the dredgings is authorized for dumping at sea in geographically delimited areas and following an impact evaluation of their potential harmfulness to the marine environment. The environmental risks assessment linked to dredging operations relies on knowledge related to several scientific disciplines contributing to changes in the regulations. This work, intended both for managers and for environmental scientists and engineers, is designed to take stock of the current state-of-the-art in the field of sediment contamination and related ecotoxicological hazards, along with a review of...

Étude d'impact du "Gino" - Résultats de la campagne "Gino II" ArchiMer
Michel, Pierre; Abarnou, Alain.
La campagne "Gino II" réalisée par l'I.S.T.P.M. en avril 1981 à bord du N/O "Pelagia", et les études en laboratoire qui ont suivi, permettent de faire le point de la contamination et de noter l'évolution. - Dans les sédiments, à la périphérie d'une nappe de Carbon Black oil dont la surface est restreinte, on peut noter une contamination parfaitement discernable dans un cercle de 8 milles de rayon. Le niveau de contamination y est toutefois peu élevé. A l'extérieur de ce cercle, aucune contamination n'a été décelée. - Les crustacés pêchés dans les parages immédiats de l'épave contiennent de faibles traces d'hydrocarbures au niveau des branchies et de l'hépatopancréas. Bien que les taux d'hydrocarbures dans les oeufs soient négligeables et que l'examen...

Influence de chocs thermiques et d'un traitement au chlore sur la croissance d'organismes phytoplanctoniques marins - 1. La diatomée Gyrosigma spencerii (Cleve) ArchiMer
Maggi, Pierre; Lassus, Patrick; Abarnou, Alain.
Les travaux présentés font partie d'une étude générale sur les effets probables de l'implantation des centrales nucléaires sur les organismes phytoplanctoniques marins. De grandes quantités d'eau de mer transitent par les condenseurs de ces centrales ou elles s'échauffent brutalement ; elles sont ensuite rejetées dans le milieu marin et y dissipent leurs calories. Afin de limiter la fixation des salissures biologiques, une injection de chlore est effectuée à l'entrée des condenseurs ; cette pollution chimique vient alors s'ajouter à la pollution thermique. Nous avons recherché, sur le développement de Gyrosigma spencerii, les effets : de chocs thermiques, d'injections de chlore, de l'association de ces deux traitements.

La chloration des effluents urbains avant rejet en mer ArchiMer
Abarnou, Alain; Guillaud, Jean-francois; Miossec, Laurence; Batt, Agnes.
Chlorination of wastewater prior to effluent discharge into the sea is used as disinfecting treatment to preserve salubrity of the coastal marine environment wich is necessary for such activities as shellfish-farming and nautical sports. The disinfecting capacity of chlorine results from its oxydizing property which gives rise to various chemical reactions with constituents present in wastes. ln wastewaters, highly loaded with organic matter and ammonia, monochloramine is the main active chlorine species. Due to organic matter oxydation, thèse active chlorine species rapidly disappear by transformation into non toxic chloride. However, a very sm ail part of the initial chlorine dose can be found as stable and toxic chloroorganics. Monochloramine is also...

Les polychlorobiphenyles ( PCB ) en Baie de Seine ArchiMer
Abarnou, Alain.
PCB contamination and i ts relationship wi th suspended particulate matter (SPM) have been studied in water from the Seine estuary and the baie de Seine, in July 1985 and February 1986. PCB chromatograms are very similar and characterize a chronic contamination. PCB concentrations vary from 2 ng/l in the marine zone up to 210 ng/l in the estuary. SPM and PCB concentrations are weIl correlated. Highest PCB concentrations are measured in February due to higher SPM inputs mainly made of finer particles.
