Biochemical and metabolomic impact of trace metals (As, Sb, Cd, Ag, La, Ce) in various fish species and amphipods collected from the metal-impacted Yellowknife area
Principal Investigator: Rosabal, Maikel
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5278. The main goal is to generate a specific knowledge about the implications of metals bioaccumulated observed in the population of three species of fish (e.g., northern pike, lake whitefish, yellow perch) and invertebrates (H. azteca) inhabiting ecosystems located in this mining region. The specific objectives are: 1) to...


Monitoring of mercury, flame retardants and other chemicals in lake trout and cisco from Great Bear Lake
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5359. This study is designed to find out whether contaminant levels are changing in fish (lake trout and cisco) in Great Bear Lake. Of particular interest is mercury. It complements ongoing fish population studies being conducted by the Department of Fisheries and Oceans on Great Bear Lake and contributes to Deline's resear...


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...


Investigating Anthropogenic Sources of Groundwater Contamination in the Canadian Arctic
Principal Investigator: Hamel, Emilienne
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5245. The objectives of this project are to contribute to the territorial government’s groundwater monitoring plan by establishing baseline conditions for solutes in the local groundwater around the solid waste facility. The research team aim to improve current groundwater vulnerability frameworks to account for anthropogen...


Potential Impacts of Climate Change on the levels of Poly- and Perfluoroalkyls in Country Foods and Implications for Human Health Risk
Principal Investigator: Wallace, Elizabeth
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5313. The objectives of this study are to estimate potential future Perfluorooctane sulfonate (PFOS) concentrations in marine country foods under two climate change scenarios, and to determine dietary exposure estimates and hazard indices based on potential future concentrations and dietary intake data. The longer-term obje...


Contaminants (PAHs, mercury) in the Mackenzie River and fish health assessments: implementation of classic and new molecular screening tools for environmental monitoring and stressor assessment
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5333. This study will determine the concentrations of Polycyclic Aromatic Hydrocarbons (PAHs) in small-bodied fish in the Norman Wells/Imperial area near nature oil seeps and industrial activities with comparisons to be made with upstream (Tulita area) and downstream (Fort Good Hope) areas. The research team will also asses...


Thompson-Lundmark Mine Remediation Project Phase III Environmental Site Assessment
Principal Investigator: Kalinovich, Indra
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5312. The objective of this project is to address the data gaps at the Thompson-Lundmark Mine site. The data collected from the field program will be used to inform the future Human Health and Ecological Risk Assessments in order to achieve appropriate remedial objectives for the site to satisfy the Federal Contaminated Sit...


Hydrocarbon-derived compounds (anthropogenic and natural) in water bodies in the Sahtú
Principal Investigator: Gurney, Kirsty E.
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5262. The research team are proposing to work with community partners to collect samples and analyze data describing concentrations of Polycyclic Aromatic Compounds (PAC’s) in the Mackenzie River and in other water bodies, along a gradient of environmental disturbance. Specifically, the program will evaluate the relative co...


Rocher River Town Site ESA
Principal Investigator: Bandler, Paul
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5297. The field program aims to fill gaps previously identified to support a human health and ecological risk assessment, as well as remedial/risk management options analysis and associated cost estimation for the Site. A Phase III Environmental Site Assessment will be completed to delineate environmental impacts, collect b...


Investigating Lead Exposure in the Sahtú region
Principal Investigator: Skinner, Kelly
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5204. This project proposes to continue investigating the determinants of lead exposure in humans and to assess health risk in the Sahtú region. This project will provide knowledge on potential strategies to reduce the lead exposures in Dene and Métis communities. The research team propose to: 1) Implement the previously...
