NWT RESEARCH DATABASE

Principal Investigator: Bidleman, Terry F.
Licensed Year(s): 1992
Summary: The researcher will collect air and water samples for analysis of toxaphene and other organochlorine compounds, as well as examining differences in toxaphene patterns in air, water and biological samples....

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: Peddle, Juanetta
Licensed Year(s): 1991
Summary: The Researchers will establish an overview of background levels of contaminants in the Mackenzie River Delta. The study includes collection of large volume water, suspended sediment and grab samples at both inflow and outflow sites of the Mackenzie River Delta. Large volume samples will be extracted at the Inuvik Research Centre, and concentrated before being shipped out for analysis....

Principal Investigator: d'Entremont, Andre
Licensed Year(s): 1991 1990
Summary: Fifty (50) sediment samples will be collected from 6 stations in Inner and Outer Sun Bay, Contwoyto Lake. The samples will be analyzed to determine whether or not there have been changes in contaminant levels since the mine became operational. Fifty (50) additional samples will be taken to look at the benthic organisms which live in the sediments....

Principal Investigator: Weis, Michael
Licensed Year(s): 1991
Summary: Through interviews and diet diaries, the patterns of consumption of "country foods" and commercially prepared foods will be assessed in seasons throughout the year. This continuing study will assess the nutritional quality of the diet and will quantify the dietary intake of contaminants....

Principal Investigator: Heinke, G.W.
Licensed Year(s): 1991 1989
Summary: In co-operation with the Department of Municipal and Community Affairs, the researcher will conduct a random sampling of garbage generated in the selected communities to establish their composition. A questionnaire will be used to gather a hazardous waste inventory. A detailed plan will be for the design and cost estimate of a co-disposal facility will be undertaken....

Principal Investigator: Metcalfe, C.D.
Licensed Year(s): 1991
Summary: The Research will examine the variation of organochlorine contaminants (O.C.'s) in the arctic ringed seal species. Major trends in concentrations will be outlined on 4 distinct levels: 1) variation within individual seals 2) seasonal variation in one seal popultion 3) variation between seal popultaions from two distinct sites 4) long-term temporal variations at these two locations....

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....

Principal Investigator: Brunskill, Gregg
Licensed Year(s): 1991 1990
Summary: The Researcher and team will obtain live fish for immediate field dissection and dry ice freezing of tissue samples for contaminant, enzyme and protein measurements. Large core samples of deep lake muds are sliced into thin layers in the field for radiochemical estimation of slice age and the measurements for organochlorines, PAHs, metals and other geochemical parameters....
