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.
chercheur principal: Stern, Gary
Année(s) de permis: 2022 2021
Résumé: This licence has been issued for the scientific research application No.5111. The short-term goals are to determine if 2020, 2021 and 2022 burbot contaminant concentrations: a) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish). The research team will provide annual data to NWT Heath and Social Services for evaluation; b) are associated with dietary indicators, i.e. sta...

The Continuation of a Community-led Fish Monitoring Study in Déline, NT 2012
chercheur principal: Macdonald, Colin R
Année(s) de permis: 2012 2010 2009
Résumé: The goal of this project is to determine the levels of potential chemicals of concern in three major fish species through the analysis of muscle and liver samples for mercury, radionuclides and a number of elements. Fish of three species (lake trout, lake whitefish and lake herring) will be collected in the Keith Arm of Great Bear Lake near the community of Deline. Approximately 15 trout and 10...

Bluefish Lake Mercury Monitoring
chercheur principal: Dewar, David J
Année(s) de permis: 2012
Résumé: The Objectives of this research project are to: 1.) gather information in 2012 on the small-bodied and Young of Year fish in Bluefish Lake that may be available for monitoring as well as determine the most suitable methods and locations for their capture in order to finalize the proposed mercury study design, and 2.) complete monitoring between 2013 and 2015 as described in the finalized mercury ...

An investigation of the factors affecting high mercury concentrations in predatory fish in the Mackenzie River Basin.
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2003 1998
Résumé: It has recently been learned that predatory fish in some lakes in the Mackenzie Basin have very high concentrations of mercury. This study will try to determine why the mercury concentrations are high. The researcher will fly into Cli Lake. A boat, a depth sounder and a global positional finder will be used to find out how deep the lakes in different spots. The temperature of the water, its acidit...
