Céline Boutin

Research Scientist - Ecotoxicology and biodiversity of habitats

CURRENT S&T / RESEARCH - Natural habitats are known to contribute positively to biodiversity, especially in areas of intensive agriculture where agrochemicals are commonly used. In other ecosystems, anthropogenic factors related to mining and oil extraction affect terrestrial and aquatic primary producers of natural environments. It is therefore critical to determine the impact of various stressors on native vegetation and other trophic levels.

  • Investigating factors, mostly pesticides, that alter biodiversity with an emphasis on plant species found in wetlands, riparian strips, woodlots, and hedgerows. With conservation of natural habitats in mind, studies are conducted in order to describe and explain richness and assemblages of vegetation within farming areas. Other trophic levels are also considered.
  • Improving methodologies currently used in phytotoxicity testing and risk assessment, especially for regulatory purposes at national and international levels. Herbicides are used extensively in Canadian agriculture with more than 26 million hectares sprayed at least once in any given year. Studies are conducted to upgrade phytotoxicity testing.
  • Studying impacts of contaminants such as Rare Earth Elements, other metals and contaminants on plants and invertebrates.


Invited member of the External Scientific Expert Working Group to review the quality of a number of scientific risk assessments conducted by the European Food and Safety Authority (EFSA). EFSA's main work is to provide risk assessments associated with food and feed safety (including genetically modified organisms), nutrition, animal health and welfare, plant health and pesticides. EFSA provides science-based advice to the European Commission, the European Parliament and the Member States.
