Spatial and long-term trends in persistent organic contaminants and metals in fish from the Northwest Territories
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2020 2019
Résumé: This licence has been issued for the scientific research application No.4818. This research will investigate whether contaminant levels are changing in fish in Great Slave Lake which the team have been studying since the early 1990s. The research team plan to work with commercial fishery and community collected lake trout from the Hay River and Lutsel K’e areas, burbot from the Lutsel K’e and F...


Spatial and long-term trends in persistent organic contaminants and metals in lake trout and burbot from the Northwest Territories

Résumé: The purpose of the study is to continue investigating whether contaminant levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which the research team has been studying since the early 1990s. The plan is to collect lake trout from Great Slave Lake (Hay River area and Lutsel K’e area). The research team also plans to collect burbot from the Lutsel K’e and Fort R...


Temporal trends and spatial variations in persistent organic pollutants and metals in sea-run char from the Canadian Arctic
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2007 2006
Résumé: This is a study investigating the contaminant levels in sea-run Arctic char as they return from feeding in the ocean. The aim of this study is to provide communities with more information on the chemical levels in these fish. By making these chemical measurements in char and comparing them with chemical levels in marine mammals, there would be a possibility to demonstrate that char is a good food ...


The Historical Record of Persistent Organic Pollutants and Trace Metals in Glacial Snow and Ice
chercheur principal: Gregor, Dennis J.
Année(s) de permis: 1994 1993
Résumé: Ice caps have been used to measure changes in the chemistry of the atmosphere over long periods of time. The studies have addressed climate change, levels of pollutants resulting from human activities, and levels of materials put into the atmosphere by natural processes (e.g., volcano eruptions). This on-going study has been examining the levels of contaminants in ice caps since 1986 by collecti...
