Summary: The seven-year objective of Sub-Arctic Meteal Mobility Study (SAMMS) is to identify, quantify, and predict mobility of natural-source and legacy mine-source metals in soil, wetlands, and lake sediments that extend from former, present, and planned mine sites currently and as climate change alters the quantity and quality of dissolved organic matter produced and exported in subarctic NWT watersheds...

Principal Investigator: Amuno, Solomon A
Licensed Year(s): 2017
Summary: The objectives of this research project are to: 1. investigate the effects of chronic arsenic exposure on reproductive parameters, specifically seminal and hormonal parameters including testicular pathology and os penis (baculum) morphology of small mammals (muskrats and squirrels) inhabiting the vicinity of the Yellowknife area, near the Giant mine, and in a reference location approximately 30-8...

Licensed Year(s): 2018 2017 2016 2015 2014 2013
Summary: The purpose of the project is to work in collaboration with Northwest Territories (NWT) communities to collect water quality data to answer community concerns and questions about the health of NWT waters, to enhance understanding of cumulative impacts and to contribute to decision making. There are three associated objectives: 1) collect water quality data at locations throughout the NWT, to ...

Principal Investigator: Blais, Jules M
Licensed Year(s): 2017 2016 2015
Summary: The research team propose to develop tools to assess risks associated with legacy industrial developments in a northern setting. The team will investigate contaminants from the Giant Mine near Yellowknife Northwest Territories (NT), which operated between 1948 and 2004, producing a legacy of contaminants including arsenic, antimony, hydrocarbons, mercury, and others. This remediation strategy appl...

Principal Investigator: Stephen, Celsian C
Licensed Year(s): 2010
Summary: The objective of this project is to enhance our understanding of the controls on the mobility of metal contaminants in mine-impacted environments. More specifically, to enhance our understanding of the role terrestrial and aquatic plants play in sequestering mine-contaminants such as arsenic, antimony, copper, lead and zinc. The field methods for this program consist of a soil and vegetation...

Principal Investigator: Blais, Jules M
Licensed Year(s): 2010
Summary: This research goal is to examine the role of thermokarst development on natural organic matter and the release of metals (e.g. mercury) and organic contaminants (e.g. polychlorinated biphenyls - PCBs). Sampling for contaminants: Water sampling for persistent organic pollutants (POPs) will be done by passive samplers, consisting of a semi-permeable membrane containing a resin that will extract ...

Principal Investigator: Seddon, Laura
Licensed Year(s): 1995 1994
Summary: This activity will help expand the human health baseline on exposure and effects of environmental contaminants on humans in the NWT. Blood will be sampled from participating mothers and from the umbilical cord to determine the levels of specific organochlorines and heavy metals. This activity will involve the participation of communities and community health workers in all aspects including desi...

Principal Investigator: Chan, L.H.M.
Licensed Year(s): 1994
Summary: The researchers will be collecting food samples and analyzing them for the presence of cadmium. The study is being conducted in concert with H. Kuhnlein's study on food use patterns in Dene/Metis communities. Thus, cadmium levels in food can be assessed in light of food consumption patterns in order to address the risks associated with consumption of foods containing cadmium....

Principal Investigator: Couture, Richard
Licensed Year(s): 1993
Summary: The researchers of Rescan have been contracted by B.H.P. Minerals Canada Ltd. to conduct an assessment of the types of fish and other aquatic organisms that are found in the Lac de Gras area. Tissue samples will be collected in order to assess heavy metal contaminants in fish. An environmental report will be submitted to the Territorial Government on the results of this study....

Principal Investigator: Harbicht, Stephen
Licensed Year(s): 1990
Summary: The Researcher and his assistants will set gill nets in Kam Lake, areas IV and V of Great Slave Lake and Yellowknife Bay to collect fish samples for analysis to determine baseline levels of heavy metals in fish tissues....
