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)
chercheur principal: Stern, Gary
Année(s) de permis: 2024
Résumé: 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...

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.4755. The short-term goals are to determine if 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. stable is...


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: 2019
Résumé: The short-term goals are to determine if 2019 burbot contaminant concentrations: 1) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish); 2) are associated with dietary indicators to determine the influence of diet (via stable isotope ratios) on contaminant concentrations in current fish, although previous results suggested no association; and, 3) as well as to look for link...

Année(s) de permis: 2018
Résumé: The short-term goals are to determine if 2018 burbot contaminant concentrations: 1) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish); and 2) are associated with dietary indicators to determine the influence of diet (via stable isotope ratios) on contaminant concentrations in current fish, although previous results suggested no association (Carrie et al. 2010); as well as...


Impact of climate change on freshwater fish mercury levels
chercheur principal: Stern, Gary
Année(s) de permis: 2012
Résumé: The objective of this study is to collect fish from lakes and tributary rivers of lakes under fish (mercury) consumption advisories and compare with older data from government if available (DFO, Environment Canada), and to collect and analyse sediment cores from these lakes to see how lake ecosystem changes relate to fish mercury levels. There are two main methods involved in this work. For fis...
