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.5058. The research team will conduct a study of Polycyclic aromatic hydrocarbons (PAHs) and mercury in large-bodied fish (primarily burbot, whitefish), small-bodied fish (trout perch, slimy sculpins, lake chub) to assess cumulative impacts of anthropogenic and natural disturbances on fish health with a focus on the Mackenzi...

Spatial and long-term trends in persistent organic contaminants and metals in fish from the Northwest Territories
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5031. The study is continuing to investigate whether contaminant levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which we have been studying since the early 1990s. The research team plans to collect lake trout from Great Slave Lake (Hay River area and Lutsel K’e area and also plans ...

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): 2024 2016 2015 2014 2013
Summary: This study is designed to find out whether contaminant levels are changing in fish (lake trout and cisco) in Great Bear Lake. The research team require a batch of spring-caught fish and a batch of summer/fall-caught fish for this study. Twenty whole lake trout and 20 whole cisco of a range of sizes are required from each collection period. The fish will be frozen immediately after capture and s...

Spatial and long-term trends in persistent organic contaminants and metals in lake trout and burbot from the Northwest Territories
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2023 2022 2017 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005
Summary: The Northern Contaminants Program (NCP) calls for monitoring of contaminant trends. Lake trout are the fish most commonly consumed and harvested. Studies are showing that contaminants such as PCBs and DDT are declining in lake trout in Great Slave Lake. Burbot liver will also be examined as part of this study because contaminant levels can be high in this organ, and contaminant levels are not decl...
