Contaminant Biomonitoring in the Northwest Territories Mackenzie Valley: Investigating the Links Between Contaminant Exposure, Nutritional Status, and Country Food Use
Principal Investigator: Laird, Brian D
Licenced Year(s): 2016 2015 2014
Summary: The overall objective of this research is to promote country foods in a way that balances contaminant risks and nutrient benefits in order to maximize nutrient status while minimizing mercury exposure. The research team will work towards this objective through the implementation of research that will consist of the biomonitoring study to evaluate country food usage patterns, contaminant exposure p...


Metal levels in large-bodied fishes near impacted lakes near Yellowknife, NWT
Principal Investigator: Somers, Gila L
Licenced 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; and 2) to monitor potential spatial and temporal trends in metal concentrations (including mercury) in fish tissues within the Yellowknife region. The data acquired will be added to existing and concurrently coll...


Monitoring of mercury, flame retardants and other chemicals in lake trout and cisco from Great Bear Lake
Principal Investigator: Evans, Marlene
Licenced 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 fall-caught fish for this study. Twenty whole lake trout and 20 whole cisco of a range of sizes are required from Great Bear Lake. The fish will be frozen immediately after capture and shipped to Environment and Climate Change Canada (ECCC)-Sask...


Updating data on mercury levels in food fish species in lakes used by Deh Cho communities
Principal Investigator: Low, George
Licenced Year(s): 2016
Summary: The objectives of this project are: 1) to determine through which lakes are important as food sources in four Dehcho communities and which fish species are used for human food from these lakes; 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 in the studies by ...


The Bio- Magnification of Mercury within Fish Species of the Deh Cho and Their Varying Levels Among Lakes
Principal Investigator: Swanson, Heidi
Licenced Year(s): 2016 2015 2014 2013
Summary: The objectives of this research project are to: 1) determine why fish mercury levels vary among lakes in the Dehcho region; 2) identify best predictors of fish mercury levels; and, 3) determine which fish have the lowest levels of mercury and highest levels of micro-nutrients and fatty acids. The methods for this project include two parts, first is the collection of food web data from each lake...


Metal levels in large-bodied fishes near communities along the Mackenzie River compared to impacted lakes near Yellowknife, NWT
Principal Investigator: Somers, Gila L
Licenced 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...

Sampling of Traditional Foods in Deline, NT in 2015/2016
Principal Investigator: Macdonald, Colin R
Licenced Year(s): 2015
Summary: The objective of the study is to obtain statistically valid numbers of samples of major traditional food items and to analyse them for chemicals of concern, including mercury, and naturally-occurring radionuclides. The conclusions of this, and previous, food studies will be communicated to the community. Approximately 20 samples of moose or caribou, fish, and waterfowl will be obtained from...


Tracing the Origin of Mercury Contamination in the Lakes and Fish of the Jean Marie River First Nation Lands
Principal Investigator: Laurent, Cyrielle C
Licenced Year(s): 2015
Summary: The short term objectives for this project are to: - Assess permafrost as a possible origin of mercury contamination; - Measure mercury content in permafrost samples; - Engage the community to exchange traditional and scientific knowledge to better understand relationships between country food, water quality, and permafrost degradation from a contamination perspective; and - Use traditional la...


Cumulative Impacts Monitoring of Aquatic Ecosystem Health of Yellowknife Bay, Great Slave Lake
Principal Investigator: Chételat, John
Licenced Year(s): 2015
Summary: The main objective of this study is to investigate the ecosystem health of Yellowknife Bay. We will address the following questions through a field study: 1) What is the quality of water and sediment in Yellowknife Bay (focusing on metals, nutrients and cyanobacteria)? 2) What are the main sources and transport pathways of metals accumulating in the food web of Yellowknife Bay? 3) How much of ...
