Metals Uptake from Vegetation to Caribou in the Canadian Arctic
Principal Investigator: Katz, Sharon
Licensed Year(s): 2007
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...


2003 Port Radium: Phase 2 Environmental Studies
Principal Investigator: MacNeill, Scott W
Licensed Year(s): 2003
Summary: This 5-day sampling program will involve fisheries, aquatic, and vegetation studies at/in the vicinity of the abandoned Port Radium Mine site. Concentrations of five biologically significant metals (antimony, arsenic, lead, nickel and zinc) will be dete...


Arsenic Speciation in Fish for Back Bay, Yellowknife, and Consequences for Human Health
Principal Investigator: de Rosemond, Simone
Licensed Year(s): 2003
Summary: The Giant Mine, Yellowknife, was in operation for more than 50 years during which time arsenic levels in the surrounding area have significantly increased due to the roasting methods used to extract gold from mined ore. Arsenic was measured in walleye (...


Trace Contaminant Transformation and Fate in Northern Ecosystems
Principal Investigator: Siciliano, Steven D
Licensed Year(s): 2003
Summary: This study will: (1) assess sulfate-reducing bacterial diversity and mercury transformations; and (2) analyze the toxicity of contaminants deposited on vegetation and soil to wildlife that may digest it. Little is known about transformations of mercury...


Inuvik Regional Human Contaminants Monitoring Program
Principal Investigator: MacNeil, Chuck
Licensed Year(s): 2000 1999 1998
Summary: The Inuvik Regional Human Contaminants Monitoring Program has finished sampling maternal scalp hair for methyl mercury analysis, and checking maternal and umbilical cord blood for certain organochlorines and metals. The communications phase is now beginning. As of March 2000 participants will have the option to review their medical health records and obtain their personal results. The compiled res...


Assessment of Dietary Benefit: Risk in Inuit Communities
Principal Investigator: Kuhnlein, Harriet V
Licensed Year(s): 1998
Summary: The objectives of this study are therefore: 1) derive quantitative estimates of traditional and market food among Inuit; 2) complete databases of nutrient and contaminant contents of traditional food; define benefits of traditional food in terms of nutritional, socioeconomic and cultural significance; define the levels of exposure to contaminants (heavy metals and organochlorines). In each commun...


Food and habitat use among fishes of the Slave River, NWT.
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...


Productivity of Marine Mammal Food Chains in the Northwest Passage
Principal Investigator: Welch, Harold
Licensed Year(s): 1993 1992 1991 1990 1988 1987
Summary: The researcher and his team will continue their marine research at Resolute. They will continue their work on the trophic dynamics of the arctic marine food chain as it pertains to marine mammal and seabird production. The main goal is to obtain data on seasonal cycles of energy flow. The team will also be examining organochlorine and heavy metal contaminants in the marine system....


A Study of Polonium 210 and Lead 210 in Food Chains, Lichen-Caribou-Man and Lichen-Caribou-Wolf in Northern Saskatchewan and the Northwest Territories
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....


Assessment of Metal Levels in Fish Tissue from Lupin Project Area 1990
Principal Investigator: Harbicht, Stephen
Licensed Year(s): 1990
Summary: The Researcher and his team using gill nets will sample lake trout to determine the level of heavy metals in order to evaluate the bioaccumulation that has occurred....
