Enhanced Investigations of the Factors affecting Long-term Contaminant Trends in Predatory Fish in Great Slave Lake, the Northwest Territories
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2010 2009
Résumé: This licence is being issued for the scientific research application no. 991. The goal of this research is to conduct sediments coring and food web studies to better understand the factors affecting long-term contaminant trends in predatory fish in Great Slave Lake. For several years the researchers have been conducting studies to find out if contaminant levels are changing in lake trout and...

Biological studies of waters along the proposed Mackenzie Gas Pipeline route - Inuvialuit Settlement Region
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2009 2008 2007 2006
Résumé: This study is designed to fill gaps in Environment Canada’s understanding of the aquatic environment potentially impacted by various aspects of the Mackenzie Gas Project (MGP). Potential stressors including: increased erosion, nutrient releases from sewage discharges, other chemical releases, water withdrawals, impacts of barge traffic, increased atmospheric emissions, etc. The focus will be on th...

Spatial and long-term trends in persistent organic contaminants and metals in lake trout and burbot from the Northwest Territories
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2023 2022 2017 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005
Résumé: The researchers are trying to determine whether contaminant levels are changing in lake trout and burbot in the Northwest Territories. The researchers will focus their analyses on contaminants such as PCBs, DDT, toxaphene and mercury but also will analyze a subset of fish for new compounds of concern. During the project, 20 lake trout will be collected from each of the four study locations and ...
