Ekati Wildlife and Human Health Risk Assessment Final Report (BHP Billiton, January 2006)
This final risk assessment evaluates potential health risks to wildlife and humans from exposure to metals in processed kimberlite at the EKATI Diamond Mine's Long Lake Containment Facility, where vegetation cover is proposed as a reclamation option. The assessment identified ten metals of concern and predicted acceptable risks for most wildlife receptors and human consumers of caribou and goose, with the exception of potential unacceptable nickel risks for humans consuming caribou under elevated soil ingestion scenarios.
