Christian Blaise

Research Scientist - Aquatic Ecotoxicology, Fluvial Ecosystem Research


Contribution to the protection and conservation of aquatic ecosystems

  • Development/application of bioassays and biomarkers for the study of the aquatic environment
  • Experiments on aquatic food chains to assess the potential for contaminant bioaccumulation/biomagnification
  • Assessment of the toxic potential of complex matrices (liquids and solids) and emerging substances (pharmaceuticals, nanomaterials)
  • Impact studies of mixed and non-point source pollution on water quality in the Saguenay Fjord demonstrated using a bivalve model (Mya arenaria)
  • Technology transfer of ecotoxicological tools at the (inter)national level, publication of books and writing of summary articles in the field of aquatic ecotoxicology


Co-chair of the International Steering Committee of the International Symposium on Toxicity Assessment (ISTA)

Member of the editorial board of scientific journals: Environmental Toxicology; Ecotoxicology and Environmental Safety; Brazilian Journal of Aquatic Science and Technology

Invited foreign member of the scientfic board of INERIS (Institut National de l'Environnement Industriel et des Risques, Verneuil-en-Halatte, France): 4-year term

Co-supervisor of three PhD students at UQAR, UQAM and the University of Sao Paulo (Brazil)
