Mercury in Fish of Natural Lakes of Northern Québecg concentrations were estimated for fish of standardized length and of the following species: longnose sucker (.), white sucker (.), lake whitefish (.), northern pike (.), walleye (.), and lake trout (Salvelinus namaycush). Mean concentrations for 400-mm non-piscivorous fish of various lakes, rangin

Mercury in Birds and Mammalslected numerous data on the levels of mercury in wildlife from both regions between 1989 and 1991. The collection of specimens was conducted with the collaboration of the local Cree trappers and Inuit hunters. Species sampled included birds (waterfowl and Gulls), terrestrial mammals (marten, mink, e

Mercury Accumulation in Fish from the La Grande Complex: Influence of Feeding Habits and Concentratiin natural lakes. Feeding habits of non-piscivorous and piscivorous fish species from the La Grande complex were studied 2 to 4 years after filling (1980 to 1982) and several years later (1992 to 1994). Results showed that non-piscivorous fish from both natural lakes and reservoirs have similar diet

Calculated Fluxes of Mercury to Fish in the Robert-Bourassa Reservoirately following the flooding of the reservoir. Fish were divided into two arbitrary groups: piscivores and prey (non-piscivores) accounting globally for more than 90% of all fish biomass captured during the 7 years period. Extensive catch-per-unit-effort data available over time was used to estimate

With the exception of eggs, which are usually laid when reservoirs are still ice covered, total Hg levels were significantly higher in the feathers of adult Osprey and nestlings living close to reservoirs than in those living in a natural environment. Despite a much higher total Hg exposur
