Environmental physical-chemistry

Dr Serge Stoll


The fate and transport of emerging contaminants in aquatic systems, such as manufactured nanoparticles and micro-plastics, introduced by human activities, needs to be understood urgently to evaluate their long-term impacts as well as their influences and effects on biota and humans. With industrialization, their fluxes and accumulation in aquatic systems have continuously increased over the past decades. Our research activities are dealing with the characterization and the understanding of the physical and chemical processes which are controlling the circulation, fate and environmental transformation of these pollutants. Research activities are developed via international, national and local collaborative projects at the academic and industrial level.

Our research domains are dealing with:

  • the behavior, transformation and interactions of manufactured nanoparticles in the environment and in the water treatment processes
  • the fate of micro plastics in the aquatic systems,  their detection, characterization and impact on water treatment process  
  • the understanding and improvement of water treatment processes with a focus on the role of coagulation       
  • the formation of complexes between (bio)macromolecules and manufactured nanoparticles in the production of new materials as well as their  behavior in biological fluids.
  • computer modeling of nanoparticles, natural organic matter and inrganic colloids heteroagglomeration

Important physico chemical processes in aquatic systems for a better understanding
of the fate of manufactured nanoparticles in aquatic systems


The group members are giving courses and practical labs on environmental physicochemical processes, chemistry of aquatic systems, and water analysis. Teaching is given at the Faculty of Sciences within the framework of the Master Universitaire of Environmental Sciences. Master, PhD students and Postdocs are welcome for training and research courses. Our research group is also regularly participating to outreach activities via interviews and public debates.
