Aquatic Microbial Ecotoxicology (EMA)

Benthic communities as a tool to assess ecotoxicological effects and ecological quality in contaminated freshwaters


While invisible to the naked eye, aquatic microbial communities contribute to a wide range of ecological functions and ecosystem services, including primary production, organic matter degradation, nutrient recycling, micropollutant dissipation and transformation. Given the widespread contamination of the environment that occurred in a context of global change, preserving aquatic ecosystem health requires to protect microbial diversity and functions from the adverse ecological effects of micropollutants and multiple stressors.


In this context, our Research Group on Aquatic Microbial Ecotoxicology combines microcosm experiments and in situ surveys to provide knowledge and develop innovative tools and approaches to:

  • Describe how micropollutants affect the vulnerability and resilience of benthic microbial biodiversity and associated ecological functions in a context of multiple stresses,
  • Evaluate the ecological quality of contaminated aquatic ecosystems through the study of natural periphytic and sediment microbial communities.

EcotoxicoMic steering committee 2024

The steering committee of the international network on microbial ecotoxicology (EcotoxicoMic) had a one day meeting at Paris on February 6, 2024 to produce an overview of 2023 activities and to prepare, among others, the 4th international conference of microbial exotoxicology (EcotoxicoMic2024) to be held in Gothenburg, Sweden, from 12 – 14 November 2024.
The meeting provided an opportunity to welcome the new members of the team, who joined us in 2024: Emilie Egea (MSCA DN Poject Manager) and Louis Susset (MSc Internship student).
Laura Kergoat (Post-Doc/Research Engineer) and Hélène Rogue (Phd Student) have presented their research during the 11th conference of the French Association of Microbial Ecology (AFEM), which took place in Carqueiranne from October 17 to 20, 2023.
