Temporal trend studies of trace metals and halogenated organic contaminants (HOCs) including new and emerging persistent compounds, in Mackenzie River burbot, Fort Good Hope, NWT (2024-2025)
Principal Investigator: Stern, Gary
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5906. Short-term goals are to determine if burbot contaminant concentrations: • Are above or below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish). Annual data will be provided to NWT Health and Social Services for evaluation; • Are associated with dietary indicators, i.e. stable isotope ratio data (15N, 1...

Nutrient and contaminant status in the wetlands of the Slave River Delta
Principal Investigator: Doig, Lorne
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5337. The objective is to answer key questions: 1. From the outer SRD (river-water dominated) to the apex of the SRD (runoff dominated), what is the current status of nutrients and contaminants in SRD wetland ecosystems? 2. How do trace elements (e.g., mercury) move through SRD wetland food webs? 3. How does water source...
