Summary: The overall objective of this research is to promote country foods in the Dehcho Region 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, c...

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...

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 ...

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...

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...

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...

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 ...

Summary: Yellowknife Bay on Great Slave Lake is a water body of cultural, subsistence and recreational importance for the Yellowknives Dene First Nation (YKDFN) and residents of Yellowknife. The ecosystem health of Yellowknife Bay has been impacted by historical mining releases of metals (particularly arsenic), as well as long-range atmospheric transport of metals such as mercury from far-away human emissi...

Summary: The objectives of this research project are to collect a series of sediment cores in the West Basin of Great Slave Lake to investigate time trends in various chemicals of interest including mercury, mercury isotopes and persistent organic contaminants. In late-March 2014, the research team will collect sediment cores at 3-4 locations on Great Slave Lake (West Basin, offshore Slave River). An 8...

Summary: The objectives are to draw together multiple sources of information so that we may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and integrate local and traditional kn...
