Dr. Amila O. De Silva

Research Scientist - Environmental chemistry of priority and emerging organic pollutants

CURRENT S&T / RESEARCH - Develop knowledge on the distribution, fate and bioaccumulation of priority substances for assessment and management of chemicals

  • Conduct bioaccumulation and biotransformation of candidate persistent organic pollutants (POPs) in aquatic organisms including invertebrate
  • Interrogate sources of candidate POPs based on environmental distribution and patterns of pollution
  • Contribute information on the environmental fate and disposition including persistence, bioaccumulation, and long range transport potential of chemicals relating to the Chemicals Management Plan
  • Studies on new contaminants in foodwebs such as those of the Great Lakes and Arctic terrestrial
