comparison of mercury concentrations in landlocked, resident, and sea-run fish (salvelinus spp.) from nunavut, canada.mercury concentrations ([hg]) in arctic food fish often exceed guidelines for human subsistence consumption. previous research on two food fish species, arctic char (salvelinus alpinus) and lake trout (salvelinus namaycush), indicates that anadromous fish have lower [hg] than nonanadromous fish, but there have been no intraregional comparisons. also, no comparisons of [hg] among anadromous (sea-run), resident (marine access but do not migrate), and landlocked (no marine access) life history type ...201121381088
eating habits of a population undergoing a rapid dietary transition: portion sizes of traditional and non-traditional foods and beverages consumed by inuit adults in nunavut, determine the portion sizes of traditional and non-traditional foods being consumed by inuit adults in three remote communities in nunavut, canada.201323724920
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 ...201524935263
mercury concentrations in arctic food fishes reflect the presence of anadromous arctic charr (salvelinus alpinus), species, and life history.single-spawning (semelparous) anadromous fishes are known to transport contaminants from marine to freshwater habitats, but little research has been conducted on contaminant biotransport by multiple-spawning (iteroparous) anadromous fishes. we examined the effect of iteroparous, anadromous arctic charr (salvelinus alpinus) on mercury concentrations ([hg]) in freshwater biota and compared [hg] between species and life history types of arctic charr and lake trout (salvelinus namaycush). data from ...201020384334
a history of total mercury in edible muscle of fish from lakes in northern canada.subsistence fishing has been an important source of food for native people in northern canada since prehistoric time. measurements of the levels of mercury in edible muscle of northern fish have been undertaken for over three decades in efforts to evaluate the risks of consuming northern fish. this report summarizes the data obtained from 7974 fish of 25 species from sites distributed from the yukon to labrador. the most abundant species were lake trout, lake whitefish, arctic char, walleye, nor ...200516169059
