Patricia L. Gillis
Research Scientist - Freshwater Invertebrate Ecotoxicology and Immunotoxicology
CURRENT S&T / RESEARCH - Contributing to Environment Canada’s mandate to conduct research on the impacts of contaminants on aquatic ecosystems
- Investigate the toxicity of waterborne contaminants (metals, chloride, municipal wastewater effluents) to freshwater mussels
- Assess the role that water quality and waterborne contaminants have in the recovery of endangered freshwater mussels
- Examine links between immunotoxicity and disease resistance in bivalves
- Employ various tools to assess the bioavailability of metals to invertebrates (including the biotic ligand model and biomarkers such as metallothioenein)
