Principal Investigator: Chan, Laurie H. M.
Licensed Year(s): 2007
Summary: Lichens, cotton grass and willows will be collected in the NWT to be used in a study of caribou diet in comparison with quantitative fatty acid signature (QFASA) and mercury analyses. Fieldwork is being conducted in correlation with a caribou serum and adipose tissue sampling project. Mercury (Hg) is a global environmental contaminant that derives mostly from burning fossil fuels. The Porcupine...

Principal Investigator: Outridge, Peter M
Licensed Year(s): 2007
Summary: The objective of this research is to reconstruct climate change information as well as recent industrial mercury and lead pollution histories for Inuvik and the lower Mackenzie River valley. To determine the above, a core sample of peat will be taken from a peat bog located near Inuvik, and analyzed for elements and dusts deposited from the air over the last 7,000 years. The site will be a...

Principal Investigator: Ford, Bruce S
Licensed Year(s): 2005
Summary: This study involves fish sampling to determine relative abundance and levels of mercury and other metals in fish tissue in Giauque Lake, Thistlethwaite Lake and Control Lake A, as well as benthic invertebrate sampling and water quality sampling in the three lakes to complement the fish sampling. 3 sites in Giauque, 3 in Thistlethwaite and one in Control Lake A will be recorded. Captured fish will ...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2003 1998
Summary: This study is based on earlier research conducted by the Department of Fisheries and Oceans which found that fish in many lakes in the Mackenzie River Basin had high mercury concentrations. This study examines the environment in which the fish live in o...

Principal Investigator: Stephens, Glen
Licensed Year(s): 1998
Summary: The objective of the work is to characterize the water chemistry of lakes with reported elevated concentrations of mercury in fish from the Mackenzie River Valley, which were sampled as part of the Department of Fisheries & Oceans (DFO) fisheries management plan. This would help to establish if there is any relationship between basic lake water chemistry and mercury levels in fish which could be u...

Principal Investigator: Puznicki, Wayne
Licensed Year(s): 1997
Summary: The objective of the study is to assess the concentration of mercury in fish, water and sediment in Bluefish and Duncan Lakes; to provide information to the Yellowknives Dene First Nation to make decisions relating to the use of fish and water from these lakes; and to correlate traditional knowledge with scientific data. Bluefish & Duncan Lakes are about 50 km to the northeast of Yellowknife. Tr...

Principal Investigator: Hermanson, Mark
Licensed Year(s): 1994 1993 1992 1990
Summary: Fish (most likely Arctic charr) will be obtained either by purchase or by individual collection to analyze for chlorinated organic industrial compounds, pesticides and mercury. Few of these contaminants were ever used in the Arctic. They have been shown to travel to the Arctic through the atmosphere and accumulate in lake sediments and in fish tissues. An attempt will be made to relate the level o...

Principal Investigator: Biggs, Homer
Licensed Year(s): 1979
Summary: To collect hair, blood and urine samples to determine the disease resistence and state of health of native people on traditional diets and those who consume large quantities of "junk" food. A comparison will be made with a control group of people from Cleveland. Lead and mercury determinations along with other heavy metals will also be undertaken on the hair and urine samples....

Principal Investigator: Hatfield, C.T.
Licensed Year(s): 1976
Summary: To carry out a fresh water fisheries study, primarily in search for spawining areas. Some fish might be tested for parasites and mercury....
