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: Reimer, K.J.
Licensed Year(s): 1994 1993
Summary: The Environmental Sciences Group has been requested by Indian and Northern Affairs to conduct environmental investigations of abandoned DEW Line sites (Intermediate sites) on or near Baffin Island. A major focus of this study is an evaluation of contaminants at the sites and their presence in the water, soils, vegetation and wildlife. The research will also identify when and where remedial measu...

Principal Investigator: Swyripa, Murray
Licensed Year(s): 1993
Summary: Northward flowing rivers are thought to be major ways in which contaminants are introduced to the Arctic Ocean. As part of an on-going study, river water and sediments will be collected over the course of the year and assessed for the presence of contaminants. A total of 12 rivers in the Canadian arctic mainland will be sampled in this study, including the Mackenzie, Coppermine, Burnside, Ellice...

Principal Investigator: Waite, Don
Licensed Year(s): 1993
Summary: In this study, we will collect air, dust and rain samples on a weekly basis at five Canadian locations during the months of June and July, 1993. Three locations are in the NWT while two locations are in Saskatchewan. The samples will be analyzed in Regina and Edmonton for the presence of certain insecticides, herbicides and PCB's that are known to be transported in the atmosphere....

Principal Investigator: Edwards, Thomas W.D.
Licensed Year(s): 1993
Summary: The proposed research is part of an ongoing program of hydrological studies in the north aimed at improving our understanding of how water cycles through natural drainage systems. This year, I will examine water evaporation on lakes and ponds that are located on mine sites: results from this research will aid in the design of better tailings impoundments containing mine wastes/contaminants....

Principal Investigator: McNaughton, Duane
Licensed Year(s): 1992
Summary: The researcher will drill and complete some 20 observation wells in the vicinity of the Fort Resolution sewage infiltration pit. Sample groundwater and analyze it for sewage derived contaminants and coliform bacteria. A report will be prepared with recommendations based on the findings and submitted to relevant agencies in the N.W.T....

Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1992 1991 1991 1990
Summary: Snow samples will be collected from approximately 30 sites across the NWT and Yukon in the spring of the year. This annual snow pack sample will allow an estimate of the quantity of organic contaminants that have been deposited over the winter season. To better understand the fate of these contaminants in the High Arctic, the researchers will undertake an intensive small basin study on Cornwallis ...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1992
Summary: The Researchers will collect a series of sediment and water samples. These will be analyzed for plant nutrients, concentration of microscopic plant cells, bacteria, suspended solids, dissolved oxygen and organic contaminants. Microscopic animals will also be netted. They will determine the abundance and composition of the animals and conduct experiments to measure their feeding rates and fat cont...

Principal Investigator: Thomas, Patricia
Licensed Year(s): 1991
Summary: The study will compare two arctic food chains, namely, lichen-caribou- wolf and lichen-caribou-human to investigate the accumulation and transfer of Polonium-210 and Lead-210. Background levels of radiation will be measured by collecting samples of lichen, caribou, wolf and human placenta....
