What is the impact of metal contamination from mining activities in the Yellowknife area on northern pike (Esox lucius) and H. azteca populations?
Principal Investigator: Rosabal, Maikel
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 55584. Considering the results obtained in our previous studies on fish and invertebrates, our main goal is to generate a specific knowledge about the implications of metals bioaccumulated observed in the population of northern pike and invertebrates (H. azteca) inhabiting ecosystems located in this mining region. Our spec...


Fate of heavy metals in lagoon and wetland wastewater treatment systems and quantification of relative impacts to downstream aquatic systems
Principal Investigator: Jamieson, Rob
Licensed Year(s): 2020 2019
Summary: This licence has been issued for the scientific research application No.4623. The overall objective of this study is improved understanding of heavy metals in Sewage Disposal Facilities (SDFs) and Solid Waste Disposal Facilities (SWDFs) in the NWT. The proposed study aims to answer the following questions: 1) What is the existing treatment capacity of SDFs in NWT for heavy metals?; 2) Are SDFs ...


Monitoring Temporal Trends of Human Environmental Contaminants in the NWT and Nunavut
Principal Investigator: Beveridge, Christopher
Licensed Year(s): 2006 2005
Summary: The overall goal of this program is to establish a time trend of specific environmental contaminants in human blood and hair. A baseline study was completed in the Inuvik region in 1999–2000. A follow-up assessment to this baseline study will be undertaken this year to observe human exposure to specific contaminants across a representative cross-section of moderately and highly exposed regions (In...


Dust Distribution and Monitoring using Lichens as Bioindicators
Principal Investigator: Wytrychowski, Scott I
Licensed Year(s): 2013 2010 2005
Summary: Air quality is an issue at mine sites, and diamond mining can contribute large quantities of dust to the air. This dust may contain elevated levels of heavy metals. Vehicle and generator exhausts also contribute to air pollution and greenhouse gases. To acheive the goal of sustainable development, Diavik policy focuses on the need to identify potential risks and set targets for pollution preventio...


Inuvik Regional Human Contaminants Monitoring Program
Principal Investigator: MacNeil, Chuck
Licensed Year(s): 2000 1999 1998
Summary: The Inuvik Regional Human Contaminants Monitoring Program has finished sampling maternal scalp hair for methyl mercury analysis, and checking maternal and umbilical cord blood for certain organochlorines and metals. The communications phase is now beginning. As of March 2000 participants will have the option to review their medical health records and obtain their personal results. The compiled res...


Environmental study of the aquatic resources of the Thonokeid Lake area
Principal Investigator: Couture, Richard
Licensed Year(s): 1994 1994 1993
Summary: The researchers will continue their study on fish and other aquatic organisms found in lakes and streams of the Thonokeid Lake area. Muscle and liver tissues of fish will be taken in order to assess levels of heavy metals. In addition, water chemistry data will be collected....


Hurwitz-Kaminak geological mapping
Principal Investigator: Aspler, L.B.
Licensed Year(s): 1993 1992
Summary: A field crew of four people will map (by foot and boat) the rocks deposited in ancient (2,500 to 1,900 million year old) basins. These rocks will also be assessed for their economic potential. The field work will also involve the collection of water, moss and lichen to determine levels of contaminants as part of the northern contaminants study funded by the Arctic Environmental Strategy....


Contaminant analyses for wildlife food sources in the Inuvialuit Settlement Region
Principal Investigator: Bell, Bob
Licensed Year(s): 1993
Summary: This project was initiated following the concern voiced by the six ISR communities about the presence and levels of contaminants in the major country food sources. Samples of body tissues will be taken from charr, whitefish, seals and belugas in order to assess for heavy metal, organochlorine and PCB contaminants. These samples will be taken while other field research is being conducted by Fishe...


Kam Lake, Yellowknife Bay/Area IV and V Great Slave Lake Fish Sampling Program
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....


Assessment of Metal Levels in Fish Tissue from Lupin Project Area 1990
Principal Investigator: Harbicht, Stephen
Licensed Year(s): 1990
Summary: The Researcher and his team using gill nets will sample lake trout to determine the level of heavy metals in order to evaluate the bioaccumulation that has occurred....
