Using Quantitative Fatty Acid Signature Analysis to Investigate Diet and Mercury in Porcupine Caribou
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...


Temporal trends and spatial variations in persistent organic pollutants and metals in sea-run char from the Canadian Arctic
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2007 2006
Summary: This study is designed to determine what the levels of contaminants are in char when these fish return from feeding in the ocean in the summer. This is the fourth year of a study investigating the contaminant levels in sea-run Arctic char as they return from feeding in the ocean. The reason this study is being conducted is to provide communities with more information on the chemical levels in t...


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...


Aquatic Studies in support of the Discovery Mine Remediation Work
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 ...


Dust Distribution and Monitoring using Lichens as Bioindicators
Principal Investigator: Wytrychowski, Scott I
Licensed Year(s): 2013 2010 2005
Summary: Air quality is an issue at mine sites, and diamond mining can contribute large quantities of dust to the air. This dust may contain elevated levels of heavy metals. Vehicle and generator exhausts also contribute to air pollution and greenhouse gases. To acheive the goal of sustainable development, Diavik policy focuses on the need to identify potential risks and set targets for pollution preventio...


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...


Temporal Variability of Stable Carbon and Nitrogen within the Food Webs of Wood Buffalo National Park
Principal Investigator: Sotiropoulos, Maria
Licensed Year(s): 2000
Summary: The extensive wetland complex in Wood Buffalo National Park (WBNP) is composed of a mosaic of shallow ponds that are unique in Canada. They are also the nesting grounds of the last migratory population of Whooping Cranes. Water, organic matter, aquatic plants and small aquatic life forms will be sampled from ponds just outside the nesting area and 0.5 km from the highway. The research team will ...


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...
