Summary: This study will serve to establish the types & levels of organochlorines and heavy metals in maternal and cord blood samples, and the level of mercury in hair samples from participants in the area served by the Inuvik Regional & Social Services Board. Sampling protocol has been outlined technical specialists in the field of organochlorine in blood and mercury in hair. Participating mothers deliver...

Principal Investigator: Little, Alison
Licensed Year(s): 1995
Summary: The researchers will sample the fishes in three areas (below the rapids at Fort Smith, at the mouth of the Salt River, and in the delta) throughout the open-water season to monitor broad patterns of habitat distribution of the different species and different sizes/ ages of each species. Fish will be collected by use of multi-mesh gill nets, set lines and seines. Fish measurements, aging structu...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1995 1994
Summary: The researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Fort Resolution and Lutsel K'e. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect invertebrates and fish samples as part of an overall study of contaminants in the lake's ecosystem....

Principal Investigator: Bong, Tom D.
Licensed Year(s): 1994
Summary: The researcher will collect fish for analyses of contaminant body burdens. The sample size for each species will be 10-15 of each sex at each sampling site. Fish will be collected using set lines set in the evening and fished overnight. Blood samples will be taken from live fish and then tissues will be sampled and sent to labs for analyses. Gut contents will be examined and the fish will be aged....

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: 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: Gregor, Dennis J.
Licensed Year(s): 1993
Summary: Contaminants are carried in the air to the arctic during the winter when large-scale wind movements bring these contaminants from industrialized locations in North America, Europe and Asia to the north. Snow can collect these compounds from the air and bring them to the ground where they can accumulate. Thus, it is important to study the amount of contaminants in snow to determine the types and ...

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...
