| spatial and temporal trends of contaminants in canadian arctic freshwater and terrestrial ecosystems: a review. | the state of knowledge of contaminants in canadian arctic biota of the freshwater and terrestrial ecosystems has advanced enormously since the publication of the first major reviews by lockhart et al. and thomas et al. in the science of the total environment in 1992. the most significant gains are new knowledge of spatial trends of organochlorines and heavy metal contaminants in terrestrial animals, such as caribou and mink, and in waterfowl, where no information was previously available. spatia ... | 1999 | 10466229 |
| climate and physiography predict mercury concentrations in game fish species in quebec lakes better than anthropogenic disturbances. | the fluctuations of mercury levels (hg) in fish consumed by sport fishers in north-eastern america depend upon a plethora of interrelated biological and abiological factors. to identify the dominant factors ultimately controlling fish hg concentrations, we compiled mercury levels (hg) during the 1976-2010 period in 90 large natural lakes in quebec (canada) for two major game species: northern pike (esox lucius) and walleye (sander vitreus). our statistical analysis included 28 geographic informa ... | 2016 | 26825460 |

| novel brominated flame retardants and dechloranes in three fish species from the st. lawrence river, canada. | restrictions in the utilization of polybrominated diphenyl ether (pbde) mixtures have led to the increased usage of alternative flame retardant additives in a wide range of commercial applications. the present study examined the occurrence of established and emerging flame retardants (frs) in fish from a densely-populated urbanized sector of the st. lawrence river (montreal, quebec, canada). thirty-eight pbde congeners and sixteen emerging frs were determined in fish belonging to three predatory ... | 2014 | 24534698 |
