Principal Investigator:Katz, Sharon Licenced Year(s):
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 ...
Principal Investigator:Hermanson, Mark Licenced Year(s):
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...

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....

(1) To conduct an inventory of tern and gull colonies: up to 20 herring gull eggs will be collected for pesticide analysis - North Arm of Great Slave Lake. (2) To conduct investigations into the concentrations of arsenic and heavy metals in ducks - Yellowknife area. (3) To conduct annual breeding bird census programs - Yellowknife area....
