Bioaccumulation of Brominated Flame Retardants, Currently Used Pesticides, and emerging metal trends in the Vegetation-Caribou-Wolf Food Chain
Principal Investigator: Katz, Sharon
Licensed Year(s): 2009
Summary: The objectives of this study are: (a) To determine whether brominated flame retardants (BFRs), current use pesticides (CUPs), perfluorinated compounds (PFCs), and mercury bioaccumulate using the vegetation-caribou-wolf food chain and the Bathurst caribou herd as a model; (b) To explore possible sources of lead contamination in the Bathurst herd caribou; (c) To elucidate the pathway of lead uptake ...


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...


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...


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...


Studies on the past, present and future ecological impact on Canadian northern boreal forest and arctic ecosystems due to mining activities, shown at the Great Slave Lake area, Northwest Territories, Canada
Principal Investigator: Steinecke, Karin
Licensed Year(s): 1998 1997
Summary: The project will focus on understanding, analyzing and evaluating the reactions of the northern boreal forest ecosystems in the Great Slave Lake region due to man made stress of mining, settlement and connecting activities. The project will try to develop some general conclusions, statements and model systems. The research team (2 persons) will come from Europe to Yellowknife by plane. The base wi...
