Current Postdoctoral Scholars

  • Dr. Fiorella Barraza: Impacts of atmospheric dust deposition (from bitumen mines, dry tailings, gravel roads) on the speciation of trace elements in snowmelt and peatland surface waters.
  • Dr. Mandy Krebs: The potential environmental impacts and ecological significance of trace elements in aquatic industrial particles, including those present in treated oil sands process water released to the Athabasca River. The aim of my project is to determine which trace elements are directly bioavailable ionic species, and which are bioaccessible and may become bioavailable during ingestion to evaluate the risks to the health of aquatic ecosystems.
