Pollutants

Ecodynamics and ecotoxicology of xenobiotics

General objectives

This workshop will focus on studying the behavior, fate, and effects of pollutants in the broad sense (persistent organic pollutants, emerging organic pollutants, trace metals, nanoparticles, plant protection products, microplastics, etc.) in continental ecosystems, from their sources to their incorporation into food webs and their health impacts. The aim is to understand the mechanisms of transport, exchange, and (bio)transformation of pollutants within and between the atmosphere-soil-water-organisms compartments (environment-biota continuum) and their effects on biological mechanisms, from the cell to the ecosystem.

Keywords: Spatio-temporal dynamics of pollutants; Sources/cycles of pollutants in the environment; Environmental chemistry; Interface processes; Critical zone; Ecotoxicology; Ecosystem functionality, exposure and bioaccumulation, link between pollutants and environmental health.

Workshop activities

This cross-disciplinary workshop aims to develop the scientific interactions (chemistry-physics-biology-modeling) necessary to understand the spatio-temporal dynamics of pollutants and the mechanisms that affect the functioning of the biosphere.

To this end, the workshop will be organized around several types of activities:
– Exchange days (annual seminars, guest lectures, etc.)
– Workshops (technical means of analysis, data processing, bioinformatics, etc.)
– Dissemination of information (announcements of conferences, training courses)
– Establishment of a “suggestion box” and a five-year outlook

Referents and group members

Cross-disciplinary theme led by Muriel Raveton (LECA), Emilie Lyautey (CARRTEL), Christine Baduel (IGE), Stéphane Guédron (ISTerre)

Scientific committee: Jean Martins (IGE), Géraldine Sarret (ISTerre), Gaëlle Uzu (IGE)
