Department UMR 5255 ISM - LPTC and UMR 5805 EPOC - GEMA Arcachon
Country France
Region Aquitaine

The departments belong to the CNRS. Their aims are fundamental research in ecotoxicology, littoral oceanography and paleoclimatology as well as expertise and transfer of knowledge in the related fields. They integrate scientists in a multidisciplinary approach from several areas of science and technology of the CNRS and other institutions (chemists, biologists, mathematicians, physicians ...). The departments have developed for several years works dealing with the presence, analysis, bioaccumulation and toxicity of several ubiquitous organic and inorganic pollutants and their reactivity in the environment. More precisely they have more than 15 years of expertise in brackish and marine pollution study: detection and impact characterization. They have developed original methodologies for the analysis of pollutants in various environmental compartments and they have a large experience to study toxicity mechanisms.

Partner Skills

The unit has developed pluridisciplinary skills related to analytical chemistry, ecotoxicology and ecophysiology in aquatic ecosystems, and have experience in:

- Study of biogeochemical cycles and toxic impacts of inorganic and organic pollutants; 

- Development of analytical tools for the determination of chemical pollutants; 

- Development of passive samplers; 

- Development of an integrative online biosensor;

- Study of the toxic effects of organic and trace metals pollutants (from organismic to cellular and genetic levels, including embryo-, geno-, and repro-toxicity); 

- Study of the interactions between contamination process and physiological status; 

- Pollution biomonitoring in pilot estuarine and coastal sites; 

- Risk assessment in aquatic ecosystems using a multi-parametric approach (bioassays, biomarkers, chemical analyses);

- Ecophysiology;

- National and international expertise for decision making at governmental levels.


The units have participated in many programs at national and international levels in the last 10 years including more than 10 EU research projects and more than 10 national French projects dealing with environmental sciences ("Biological effects of environmental pollution in marine coastal ecosystems" (BEEP); "Screening method for water data information in support of the implementation of the water framework directive (SWIFT-WFD); Ecotoxicological and economical liability of eel exposed to seasonal and global change-induced O2-depletion and pollution in estuaries (ANR VMC EEL-scope)). 
The sophisticated equipment of the units offers suitable analytical and experimental facilities for trace level determinations and chemical toxicity assessment. 
They have strong collaborations with public agencies responsible for water quality (French Water Agencies, IFREMER). They are also involved in national and international expertises (for example heading the International Expertise Group on the putative impact of the Goro-Nickel effluent in New-Caledonia; scientific council of ONEMA), and have published more than 150 papers in the field since 2005.
Participation in the Work Plan
The departments of the CNRS will participate in activity 6 "Indicators - Monitoring" and activity 8 "Communication", and will also contribute to activity 7 "Decision Supporting System - Case studies".
They will carry out studies on the water and sediment quality in harbours, using in situ testing, in situ monitoring of the organic pollutants; and characterization of the contamination and the toxicity of collected samples (water, sediment and biota). They will deploy modern tools in harbours, such as integrative passive samplers and an online biosensor.
They will provide a case study on the port of Bordeaux.
