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): 2020 2019
Summary: 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...


Tundra Mine Remediation Risk Assessment
Principal Investigator: Corrin, Natasha
Licensed Year(s): 2016
Summary: The overall objective of the Tundra Mine risk assessment is to facilitate project closure by determining if there are any residual risks to human health or ecological receptors, including aquatic life, associated with the proposed tailings remediation. If any risks remain, the goal is to provide recommendations for risk management. In support of the risk assessment, and in order to collect baselin...


Metal levels in large-bodied fishes near communities along the Mackenzie River compared to impacted lakes near Yellowknife, NWT
Principal Investigator: Somers, Gila L
Licensed Year(s): 2016
Summary: The objectives of this project are to collect fish tissue samples from species of subsistence importance to (1) establish a long-term community monitoring program for contaminants in fish within the Gwich’in Settlement Area; and (2) to monitor potential spatial and temporal trends in metal concentrations (including mercury) in fish tissues within the Mackenzie River watershed and the Yellowknife r...


Updating data on mercury levels in food fish species in lakes used by Deh Cho communities
Principal Investigator: Low, George
Licensed Year(s): 2016 2015 2014 2012 2011
Summary: The objectives of this project are: 1) To determine which lakes are important as food sources in four Dehcho communities and which fish species are used for human food from these lakes using Traditional Knowledge. 2) To train community monitors to collect fish and other samples according to Environment Canada and Department of Fisheries and Oceans protocol. 3) To involve local school children i...


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): 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...


Effects of Athabasca and Slave River Sediments affected by oil sands operations on embryonic fish
Principal Investigator: Jones, Paul D
Licensed Year(s): 2013 2012 2011
Summary: The research team will quantify the effects of exposure of embryonic fish to contaminants released from oilsands operations that may be present in the sediments. The research team will drill a hole in the ice, no more than 12 inches in diameter, and use sediment collection equipment to collect a few centimeters of sediment from the river bed. Local communities will have an opportunity to as...


Giant Mine Phase 4 Environmental Effects Monitoring
Principal Investigator: Harris, Katherine M.
Licensed Year(s): 2012 2010
Summary: The objective of this study is to examine the health of two small-bodied fish species (Slimy Sculpin and Ninespine Stickleback) exposed to treated effluent from Giant Mine. Data collected during this study will be assessed to determine if there are treated effluent related effects. The study will be conducted within the exposure areas (Baker Creek and Yellowknife Bay) and the reference areas (Yell...


Multi-scale environmental health implications of the Athabasca oil sands for Aboriginal communities in Alberta and Northwest Territories
Principal Investigator: McLachlan, Stephane M
Licensed Year(s): 2012 2011
Summary: The overall goal of this project is to better understand and communicate the implications of industrial activity associated with the Athabasca tar sands and large scale hydro developments for environmental and human health as it affects the downstream Aboriginal communities. The team completed Phase One of this project (collection of video and interview materials related to observed changes in ...


Miramar Con Mine Environmental Effects Monitoring (EEM) Phase 3 Study – Investigation of Cause
Principal Investigator: Machtans, Hilary
Licensed Year(s): 2018 2015 2012 2009 2007
Summary: The EEM will investigate the cause of differences in fish health that were observed in fish from an area exposed to mine effluent (Jackfish Bay) when compared to fish not exposed to mine effluent (Horseshoe Island Bay). Data will be examined to see what environmental factors are causing the observed effects. Fish Program: A small-bodied fish survey will be conducted within one exposure ar...


Aquatic Studies along the Mackenzie River and its Tributaries
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2005
Summary: This study is designed to investigate various measures of small fish health at a number of locations along the Mackenzie River. The researchers want to find out if small fish health is different near oil seepages and the islands at Norman Wells than in other parts of the river. Also, the researchers will investigate fish and benthic invertebrate abundance and species composition at selected strea...
