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...

Dust Distribution and Monitoring using Lichens as Bioindicators
chercheur principal: Wytrychowski, Scott I
Année(s) de permis: 2013 2010 2005
Résumé: 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...

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....
