| The aim of this study was to test field relevance of the prospective methodology for the assessment of environmental risk described in the EU technical guidance document (TGD) [European Commission 2003. Technical guidance document in support of Commission Directive 93/67/EEC on Risk assessment for new notified substances and Commission Regulation (EC) No 1488/94 on Risk assessment for existing substances and Commission Directive (EC) 98/8 on biocides, second ed. European Commission, Luxembourg, Part 1, 2 and 3, 760pp.]. To achieve this goal, an environmental risk assessment was performed according to the TGD for two major contaminants, atrazine and diuron, that are present in the Seine River estuary (France) and listed in the EU Water Framework Directive... |

| This study contributes to inventory programme on emerging pollutants in French waters and to the general reflection which will enable to update the list of relevant substnaces to be included in the new monitoring programmes to come. This work concerns the coastal part of the inventory programme on marine waters and sediments of France and five overseas french departments (OFD). In this goal, passive sampling techniques and direct extraction techniques have been tested through the implementation of in situ systems integrators POCIS (Polar Organic Chemical Integrative Sampler) and the extraction by SBSE bars (Stir bar sorptive extraction) directly in the waters sampled. Finally, analyzes of sediment completed the acquisition of data. Arount 40 stations were... |

| 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... |

| 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. |

| 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". |

| 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... |

| Analyse moléculaire de la mutagénèse Pour prédire les effets à long tenne de l'exposition aux polluants, la recherche s'oriente sur le développement, la validation et l'application de biomarqueurs de mutagénèse. Les mutations sur les gènes associés au développement tumoral peuvent être détectés dans des stades précoces du cancer, c'est le cas des gènes de la famille Ras et du gène supprésseur de tumeur P53. Les travaux ont porté sur l'étude de l'activation du protooncogène Ras chez les poissons, pour savoir si elle pouvait être corrélée avec l'apparition de tumeurs et à la présence de contaminants cancérigènes. Les exons 1 et 2 du gène Ras de Callionymus lira et de Mullus barbutus ont été amplifiés, clonés et séquencés pour détecter des mutations liées à... |

| 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... |

| 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... |

| Tetrachloroethylene, a chlorinated solvent, is detected in the plume of East-Toulon domestic wastes treatment plant. Its subletal toxicity was tested du ring 31 days in a flow-through system at Pen Bron aquaculture centre, using swampshrimp Palaemonetes varians as test organism. Under expérimental conditions : natural variations in temperature and salinity , normal pH, ammonia and dissolved oxyg~n values, running tetrachloroethylene concentrations (10, 100 and 500 µg.l-1) induced neither mortalities nor any change in molting frequencies of experirnented animaIs. Histology of gills in contaminated animaIs showed several non specific deteriorations which could be observed either in control or assay animaIs. Necrosis levels nevertheless, seem to increase in... |

| 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... |

| 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),... |
