Bioaccumulation of Brominated Flame Retardants, Currently Used Pesticides, and emerging metal trends in the Vegetation-Caribou-Wolf Food Chain
chercheur principal: Katz, Sharon
Année(s) de permis: 2009
Résumé: 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
chercheur principal: Chan, Laurie H. M.
Année(s) de permis: 2007
Résumé: 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
chercheur principal: Katz, Sharon
Année(s) de permis: 2007
Résumé: 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...

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
chercheur principal: Thomas, Patricia
Année(s) de permis: 1991
Résumé: 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....
