Fate and transport of inorganic and organic contaminants
  •  Fate of contaminants in indoor environments and human exposure
    • Measurement of indoor concentrations and fate of semi-volatile organic compounds, notably halogenated and organophosphate flame retardants, phthalates and PAHs
    • Development of Multimedia Indoor Model or MIM
    • Development of indoor passive air sampling methods
  • Fate of contaminants in lakes
    • Mass balance modelling of contaminants and polyunsaturated fatty acids in Great Lakes and food webs, “Areas of Concern” Bay of Quinte, Hamilton Harbour and Spanish Harbour, and Lake Winnipeg. Contributor to development of Remedial Action Plans (RAPs) and Lake Wide Management Plans (Lake Erie, Lake Ontario)
    • Coupling our multispecies mass balance model with chemical speciation-complexation and toxicity models
    • Measurement of current use chemicals in Arctic air and water
  • Fate of contaminants in urban areas
    • Determining ambient concentrations and fate processes of semi-volatile organic contaminants in urban media, including development of analytical methods and event-based sampling of urban streams
    • Developing Multimedia Urban Model (MUM) with application to Toronto. Includes spatial and temporal resolution, merging air dispersion module, linkage to GIS.

Exposure and Health Effects of Contaminants in the Environment
  • Estimating human exposure to indoor contaminants
  • Evaluating potential health effects
    • Balancing potential health benefits and risks from omega 3-fatty acids and contaminants in fish.
  •  Life Cycle Assessment
    • Within Life Cycle Impact Assessment, development of characterization factors for metals including fate and effects modelling


Chemical Management
  • Quantifying inventories and Material Flow Analysis of regulated chemicals (PCBs, PBDEs)
  • Analysis of policies, legislation and regulations related to chemical management, as well as flammability codes and standards
  • Measurement and estimation of physical-chemical properties of semi-volatile organic compounds of concern
  • Planetary boundary for chemical pollution
  • Chemical Footprint
