Looking at biological community level to improve ecotoxicological assessment of freshwater sediments: report on a first French-Swiss workshop

The first French-Swiss workshop on ecotoxicology of freshwater sediment communities was co-organized by the French Research Institute of Science and Technology for Environment and Agriculture (Irstea) and the Swiss Centre for Applied Ecotoxicology (Ecotox Centre EAWAG-EPFL) in Villié-Morgon (Beaujolais Region, France) on April 27–28, 2017. The workshop brought together scientists working in different fields of expertise (ecotoxicologists, ecologists, environmental chemists…), environmental stakeholder groups and managers, as well as economic players (start-ups and consultancies) to better connect research needs of potential end-users with research outputs. The objectives of this workshop were (i) to establish the state of the art of research in the characterization of sediment contamination and in the evaluation of the effects on sediment-associated biological communities and ecosystem functioning and (ii) to give an overview of the French and Swiss regulations dealing with the assessment of contaminated sediments in freshwater ecosystems. The ultimate goal was to collectively identify research needs and knowledge gaps, as well as to highlight ways to improve the ecotoxicological assessment of sediments in freshwater environments by further considering the structure and functions of associated microbial and invertebrate communities.

We would like to thank the Municipality of Villié-Morgon for granting us the space to host our workshop and our colleagues from Irstea who were closely involved in the workshop organization: Vanessa Aburegaiba, Catherine Ambroise-Rendu, Anaïs Charton, and Bernard Motte. We are also grateful to Dr. Inge Werner for her careful reading of and valuable comments on the manuscript.
This workshop benefited from funding from the Auvergne-Rhône-Alpes Region, the French Research Institute of Science and Technology for Environment and Agriculture (Irstea) and the Swiss Centre for Applied Ecotoxicology (Ecotox Centre Eawag-EPFL).
