| 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... |

| RAPPEL DES OBJECTIFS - Les objectifs visés par l'étude à l'origine du présent contrat consistaient à proposer et réaliser une démarche d'analyse prévisionnelle des risques environnementaux applicable aux boues de dragages des ports maritimes et à leur immersion. L'objectif final était de fournir aux services portuaires et aux Cellules de la Qualité des Eaux Littorales du Ministère de l'Aménagement du Territoire et de l'Environnement, une méthodologie de prévision des risques environnementaux des immersions des matériaux de dragage, facilitant ainsi leur gestion. |
