Summary:

  • Lack of pre-industrial baseline data hampers assessment of oil sands river pollution.
  • We analyzed metals concentrations in cores of Athabasca Delta floodplain lakes.

  • No enrichment was detected for metals associated with oil sands development.

  • Results inform decision on World Heritage status of Wood Buffalo National Park.

  • A framework has been established for ongoing aquatic ecosystem monitoring.
