Summary: The objectives of this research are two-fold: 1) Identify an ecological indicator that can monitor changes in loadings of metals in the South Nahanni Watershed. This work is scheduled for completion in 2007-2008. 2) Establish a monitoring program that can quantify the cumulative effects of mining activities on the health of streams in the South Nahanni Watershed. This work is scheduled for compl...

Summary: The monitoring objectives of this project are: to conduct a targeted scientific program to analyze heavy metals and trace elements and stable isotopes in vegetation (caribou food); to correlate the results in vegetation with concentrations in caribou from a related NCP program [Gamberg 2006]; to test if contaminant patterns in caribou tissues will vary with patterns observed in lichen/moss, or wil...

Summary: This is a study investigating the contaminant levels in sea-run Arctic char as they return from feeding in the ocean. The aim of this study is to provide communities with more information on the chemical levels in these fish. By making these chemical measurements in char and comparing them with chemical levels in marine mammals, there would be a possibility to demonstrate that char is a good food ...

Summary: Currently, there is no information about the bioavailability and toxicity of metals in the Slave River delta. The goal of this research is to examine metal cycling pathways in the delta and to assess the role of aquatic vegetation for metal accumulation...

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...

Summary: Rescan Environmental Services Ltd. will continue their study on the types of fish and other aquatic organisms found in the Thonokeid Lake area. Data on species type as well as their age, abundance and habitat will be collected. In addition, muscle and liver tissue of fish will be collected in order to assess for the presence of heavy metal contaminants. This study will be summarized in an envir...

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....

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....

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 Spyder Lake 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: Johnston, Laura
Licensed Year(s): 1993
Summary: Samples of sediment, water and different marine species such as fish, marine invertebrates (including sea urchins, clams and crabs), and microscopic organisms will be collected by divers from the underwater dumpsite in Cambridge Bay. These samples will be assessed for contaminants such as heavy metals and PCB's. The study is primarily being conducted to determine if the waste materials of the du...
