Bioaccumulation of Brominated Flame Retardants, Currently Used Pesticides, and emerging metal trends in the Vegetation-Caribou-Wolf Food Chain
Principal Investigator: Katz, Sharon
Licenced 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 ...


Organochlorine Industrial Compounds, Pesticides and Mercury in Fish From the Belcher Islands Region, Northwest Territories, Canada
Principal Investigator: Hermanson, Mark
Licenced 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...


Climate Change and Postglacial Paleoenvironmental History of Peatlands in the Mackenzie Delta Area and Anthropogenic Contaminant Residues in Active Peat Bogs in the Yukon and Northwest Territories
Principal Investigator: Vardy, Sheila
Licenced Year(s): 1993 1992
Summary: This research is part of a Canadian-Russian collaborative, interdisciplinary project aimed at the history of treeline fluctuations in circumboreal regions. We will also investigate the feasibility of using peat as a temporal record of pesticide residues. It will also investigate methods utilized in temperate peat studies and the applicability of these methods in northern Canada....
