François Gagné

Research Scientist - Molecular Ecotoxicology Specialist

CURRENT S&T / RESEARCH - Contribution to the protection and conservation of aquatic ecosystems

  • Molecular ecotoxicology of aquatic contaminants; development of biomarkers/bioassays to measure the cumulative effects of emerging substances (pharmaceuticals and nanotoxicology) in aquatic ecosystems
  • Evaluation of City of Montreal effluent disinfection processes on endocrine disruption and the effects of pharmaceuticals in mussels and fish
  • Presence of Bacillus thuringiensis cry1Ab genes and transgenic corn in the aquatic environment. Immunotoxicological effects of commercial microbial consortia products in bivalves
  • Study of the quality of the Saguenay Fjord by measuring selected biochemical and physiological effects in soft-shell clams. Health effects of warming in soft-shell clams


Ecotoxicology, neuroendocrine disruption in mussels and fish caused by urban discharges

Aquatic nanotoxicology
