A 3-year survey was made of several biological markers in mussels (Mytilus edulis) exposed in situ to the oil that came ashore after the wreck of the "Erika" tanker on the Brittany (France) coast in December 1999. The mussel response was assessed using a set of 7 biomarkers, most of them related to the metabolism of organic contaminants. After a series of validation tests, data was evaluated for only 5 biomarkers: acety1cholinesterase (AChE), glutathione S-transferase (GST), catalase (CAT), malondialdehyde (MDA) and deoxyribonucleic acid (DNA) adducts. No significant reductions in GST or CAT levels were observed, levels of DNA adducts and MDA were high during the 6 months immediately following the accident and levels of AChE were significantly lower during...

Contamination des milieux aquatiques par les substances pharmaceutiques et cosmétiques - Etat des lieux et perspectives
Provedor de dados: 5
Autores: Collette-bregand, Maude; James, Alice; Munshy, Catherine; Bocquene, Gilles.
This document reports a survey of the aquatic contamination by cosmetics and medicinal products for human and veterinary uses. The contamination of the continental, estuary and coastal waters by these substances gives rise to questions on environmental risk assessment and management. Among the pharmaceutical classes involved, substances such as anti-inflammatory drugs, steroid hormones, antibiotics and hypolipemiants are of particular concern. Present regulations do not take into account the medical effluents in the environment. A significant part of these substances is not destroyed in water treatment plants whereas veterinary substances are directly spread in the environment. Some molecules occur in particularly high concentrations as shown for...

Effets létaux et sublétaux à long terme d'un nonylphénol polyéthoxyle, le NP 5 sur la civelle
Provedor de dados: 5
Autores: Bocquene, Gilles; Miossec, Laurence.
Studying different concentrations, we have determined LT 50 of a non-ionic surfactant on elver eel: the polyoxyethylated nonylphenol NP 5. Then we studied sorne sublethal effects on fish behaviour and histological effects on gills, during 21 days. We demonstrated primary effects on gills structure and we believe in an impairing of the central nervous system.

Effets endocriniens des contaminants en milieu marin
Provedor de dados: 5
Autores: Melis, Blandine; Bocquene, Gilles; Raffin, Bernard.
This report presents the state of art of endocrine disruption aspects in ecotoxicology. Some contaminants of the aquatic environment are able to mimic female fish hormones and thereby cause inappropriate feminisation of male fish. This feminisation involves artificial induction and emergence of ovotestis in male (oestrogenic disruption). Natural and synthetic oestrogenic hormones and several contaminants (alkylphenols, PCBs, phtalates and some pesticides) are already known to cause widespread feminisation of male. Two different types of analysis can be performed to detect oestrogenics effects. Immunochemical analysis of plasma (Enzyme-linked immunosorbent assay ELISA and radioimmuno assay RIA) shows that xenoestrogens induce vitellogenin and protein zona...

Provedor de dados: 5
Autores: Burgeot, Thierry; Bocquene, Gilles; Truquet, Philippe; Le Dean, Loic; Poulard, Jean-charles; Dorel, Didier; Souplet, Arnauld; Galgani, Francois.
An oceanographic cruise in 1991 along the English Channel and Atlantic coasts of France indicated the value of dragonet Callionymus lyra Linnaeus, 1758 as a target species for monitoring biological effects. Ethoxyresorufin-O-deethylase measurements in this species provided a first assessment of the effects of hydrocarbons (PCB, PAH, dioxins) on the marine environment. The specific behavior of dragonet was defined by biochemical characterization. Biological data were obtained during 3 additional oceanographic cruises to study changes in the abundance and distribution of the species in the English Channel and the Bay of Biscay. This first assessment, carried out in the context of the National Observation Network, indicated that pollutants do not have...

Link between exposure of fish (Solea solea) to PAHs and metabolites: Application to the "Erika" oil spill
Provedor de dados: 5
Autores: Budzinski, Hélène; Mazeas, Olivier; Tronczynski, Jacek; Desaunay, Yves; Bocquene, Gilles; Claireaux, Guy.
An analytical method consisting in enzymatic deconjugation, solid phase extraction and purification, and gas chromatography/mass spectrometry analysis after derivatization was used in this study to quantify Polycyclic Aromatic Hydrocarbon (PAH) metabolites in the bile of fish. The method has been applied in a laboratory experiment studying the fate of pyrene in basin containing soles. This study has allowed the identification of 1-hydroxypyrene as the single metabolite in bile after enzymatic deconjugation. In a second time, 1-hydroxypyrene has been used as a biomarker of exposure in the case of the "Erika" oil spill. This biomonitoring was successful in demonstrating the exposure of juvenile soles to PAHs present in the "Erika" fuel oil.

In order to estimate the effects of chlorine used in cooling systems of electric power plants on zooplankton, some experiments have been realized with the four first larval stages of the prawn (P. serratus Pennant). Chlorine injection was performed by constant adding at 16 and 20 degree C with times exposures of 5, 15 and 25 minutes. If there is no detectable variations in sensitivity of different stages, toxic effects of oxydants issued from chlorination can be observed (for both the two acclimatation temperatures) at 15 minutes exposure with a LD 50 : 32 mg/l of chlorine.

Contamination of some aquatic species with the organochlorine pesticide chlordecone in Martinique
Provedor de dados: 5
Autores: Coat, Sophie; Bocquene, Gilles; Godard, Eric.
Martinique is a French overseas department whose economy relies heavily on agriculture. Organochlorine pesticides, mainly chlordecone, were used for banana cultivation to eradicate banana weevil over a period of 40 years. Chlordecone is chemically stable,and has a strong affinity for fatty tissues. It is therefore able to bioaccumulate in animals and thereby represent a threat to ecosystems and man. Soils from banana plantations in Martinique are heavily contaminated with chlordecone. Possible transfer of these molecules from agricultural watersheds to the aquatic environment and the organisms that live in it is feared. The hypothesis that ecosystems of Martinique might be highly contaminated with this organochlorine pesticide was investigated. Chlordecone...

Chlordecone in the marine environment around the French West Indies: from measurement to pollution management decisions
Provedor de dados: 5
Autores: 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,...

L'acétylcholinestérase, marqueur de neurotoxicité. Application à la surveillance des effets biologiques des polluants chez les organismes marins
Provedor de dados: 5
Autores: Bocquene, Gilles.
Les cholinestérases et particulièrement l'acétylcholinestérase (AChE) constituent la cible privilégiée de nombreuses molécules neurotoxiques notamment des insecticides organophosphorés (OP) et carbamates. La sensibilité des cholinestérases à ces inhibiteurs est aussi complexe que le polymorphisme de ces enzymes. L'utilisation des niveaux d'activité des cholinestérases comme marqueur d'exposition aux neurotoxiques dans le milieu marin implique donc une connaissance approfondie du polymorphisme de i'enzyme, de Ja sensibilité des formes AChE identifiées et des contaminants neurotoxiques susceptibles de provoquer des variations dans l'activité de cette enzyme chez les organismes marins. Aprés une synthèse des connaissances sur le polymorphisme des...

Monitoring of pollutant biochemical effects on marine organisms of the french coasts
Provedor de dados: 5
Autores: Galgani, Francois; Bocquene, Gilles; Truquet, Philippe; Burgeot, Thierry; Chiffoleau, Jean-francois; Claisse, Didier.
The establishment of a network to assess pollutant effects is a current concern of international bodies such as the North Sea Task Force, the International Council for the Exploration of the Sea and the Intergovernmental Oceanographic Commission. With respect to the French coasts, three major considerations have been defined : the choice of monitoring areas ; the determination of a target species according to different criteria such as wide distribution, limited migration and contact with pollutant-rich sediments; and the selection of suitable parameters. This paper concerns the strategy adopted for the French coast. Ethoxyresorufin-O-deethylase, a specific cytochrome P450-dependent monooxygenase, measured by a simple microplate assay, was selected as an...

Pesticide contamination of the coastline of Martinique
Provedor de dados: 5
Autores: Bocquene, Gilles; Franco, Alain.
In January and February 2002, the presence of certain agricultural pesticides throughout the coastline of the Caribbean island of Martinique was investigated. The tropical climate of the French West Indies is suitable for banana production, which requires intensive use of pesticides. An inventory of all pesticides used on the island (compounds and tonnage) was compiled. Surveys and analyses revealed the presence of pesticides in the plumes of seven rivers. The organochlorine chlordecone and metabolites of aldicarb were detected at nearly all of the monitored sites, even though the use of chlordecone has been prohibited since 1993. Two triazines (ametryn and simazine) were also identified. The concentrations of carbamates and triazines detected in the water...

Autores: 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...

The growing development of thermonuclear electric plants on coastal areas drove the I.S.T.P.M. to carry out a number of impact studies. Previous works on the impact of the transit in the condensers on the phytoplankton have been published by the Pollution Biological Effects laboratory (Maggi el al., 1979 and 1980; Lassus and Maggi, 1980). Our results on the chlorophycea Dunaliella terliolecla demonstrated that thermic elevations from low temperatures stimulated its cellular development. Therefore, it seemed interesting to measure the effects of these thermic shocks on dinophyceae (or dinoflagellates), components, with diatoms, of the coastal phytoplankton, and main agents of the summer phenomena known as "red waters".

Several bioindicators were used to evaluate the biological and genotoxic effects of marine pollutants near large coastal cities in the northwestern part of the Mediterranean Sea. Three target species of teleosts were selected: red mullet Mullus barbatus and 2 types of comber (Serranus hepatus and S. cabrilla). Induction of ethoxyresorufin-O-deethylase (EROD) activity specific for polycyclic aromatic hydrocarbons (PAH) and polychlorinated biphenyls (PCB) was measured in the livers of the fish, and inhibition of acetylcholinesterase (AChE) by organophosphorus insecticides and carbamates was measured in their muscle tissues. Maximal EROD activities (16.8 +/- 2.7 to 19.4 +/- 4.2 pmol min(-1) mg protein(-1)) recorded in red muller near Barcelona (Spain),...

Autores: Miossec, Laurence; Bocquene, Gilles; Truquet, Philippe.
Studying the impact of domestic sewer discharge on marine biota we studied lethal toxicity of tetrachloroethylene on brackish water prawn (Palaemonetes varians). These experiments were carried out in a flow-through system during 96 hours : LC 50 is 2,37 mg/l. This result and aIl data, present in litterature, show the high sensitiveness of crustaceans to this chlorinated solvent.

Evaluating the ecological impact of an oil spill is a complex issue requiring coherently articulated examination of the sequence of interactions that link the cell, where contaminants exert their effects, to the ecosystem, where interactions with human activities arise. This sequence of interactions traverses the frontiers between scientific disciplines (chemistry, toxicology, physiology, and fisheries ecology). Using the common sole (Solea solea L.) as a model species for the coastal habitats polluted by the "Erika" oil spill, our research project attempted to define indices of functional integrity that characterised the consequences of fuel exposure at the different biological levels. The coupling of field observations with experimental laboratory work...

Acetylcholinesterase activity in copepods (Tigriopus brevicornis) from the Vilaine River estuary, France, as a biomarker of neurotoxic contaminants
Provedor de dados: 5
Autores: Forget, Joelle; Beliaeff, Benoit; Bocquene, Gilles.
From April 1997 to June 1998, 14 measurements of acetylcholinesterase (AChE) enzymatic activity were performed with the copepod, Tigriopus brevicornis, collected at five stations in the Vilaine River estuary (South Brittany, France). Simultaneously, four chemical analyses of triazines and one analysis of total pesticides in water were undertaken. AChE activity levels in T brevicornis were compared to the levels measured at a reference site not exposed to effluents from Vilaine River. Results reveal significant differences between AChE activity levels depending on location of stations in the plume of the river with an increasing gradient of activity from the upstream to the downstream stations, thus indicating that neurotoxic contaminants are mainly brought...

This work is the preliminary synthesis of some toxicological tests conducted on three pesticides. This recapitulation would not have been possible without the contribution of our trainees, Misses V. Perles and H. Le Boulicot and MM. M. Falchier and G. Gaty who contributed largely to this study, supervised by the laboratory staff. The obtained results cannot be considered as definitive. The urge to answer the needs did not leave us enough time to fine tune and/or complete the results; for example we still have not determined the lethal dose for 50% of the individuals. [...]
