an assessment of the toxicological significance of anthropogenic contaminants in canadian arctic wildlife. | anthropogenic contaminants have been a concern in the canadian arctic for over 30 years due to relatively high concentrations of bioaccumulating and biomagnifying organochlorine contaminants (ocs) and toxic metals found in some arctic biota and humans. however, few studies have addressed the potential effects of these contaminants in canadian arctic wildlife. prior to 1997, biological effects data were minimal and insufficient at any level of biological organization. the present review summarize ... | 2005 | 16154621 |
estimated dietary exposure to fluorinated compounds from traditional foods among inuit in nunavut, canada. | increasing evidence shows that persistent organic pollutants such as perfluorinated compounds (pfcs) are found in the arctic ecosystem and their prevalence is causing human health concerns. the objective of this study was to estimate dietary exposure to pfcs among inuit in northern canada. perfluorooctane sulfonate (pfos), perfluorinated carboxylates (pfca c(7)-c(11)) and fluorotelomer unsaturated carboxylic acids (6:2, 8:2 and 10:2 ftuca) were measured in 68 traditional foods collected in nunav ... | 2009 | 19342075 |
the value of a polar bear: evaluating the role of a multiple-use resource in the nunavut mixed economy. | the polar bear (ursus maritimus) is a common pool resource that contributes to both the subsistence and monetary aspects of the nunavut mixed economy through its use as food, the sale of hides in the fur trade, and sport hunt outfitting. sport hunting is more financially profitable than subsistence hunting; however, the proportion of the polar bear quota devoted to the sport hunt has become relatively stable at approximately 20% across nunavut. this ratio suggests local inuit organizations are n ... | 2010 | 20648983 |
recent progress on our understanding of the biological effects of mercury in fish and wildlife in the canadian arctic. | this review summarizes our current state of knowledge regarding the potential biological effects of mercury (hg) exposure on fish and wildlife in the canadian arctic. although hg in most freshwater fish from northern canada was not sufficiently elevated to be of concern, a few lakes in the northwest territories and nunavut contained fish of certain species (e.g. northern pike, arctic char) whose muscle hg concentrations exceeded an estimated threshold range (0.5-1.0 μg g(-1) wet weight) within w ... | 2015 | 24935263 |
