Health effects of non-occupational lifetime exposure to cadmium (Cd) are of growing concern worldwide. This overview provides some context for the current situation in coastal British Columbia, Canada, which arose in 1999 from the discovery of problematic residues of Cd in farmed Pacific oysters (Crassostrea gigas). Efforts are underway to define Cd sources(More)
Eulachons return to the Fraser River each spring and migrate through the estuary to spawn in freshwater. During this migration they may be subjected to varying water quality conditions due to the discharge of domestic and industrial wastes and land drainage. Fish were captured at five estuarine stations in April 1986 and again at three stations in April/May(More)
Juvenile chinook salmon (Oncorhynchus tshawytscha) were exposed for 28 days to 0-16% treated effluent from an elemental chlorine free (ECF) bleached kraft pulp mill. Fresh effluent was diluted with river water drawn from upstream of the effluent diffuser. Fish were tested for biochemical responses to identify if the effluent would cause significant effects(More)
Juvenile Pacific salmon display a marked surface water orientation during downstream migration, estuarine and nearshore coastal rearing phases. Many estuaries in British Columbia are vertically stratified with a shallow, well-defined halocline which can restrict the dispersion of wastes discharged into less saline surface waters and impose constraints upon(More)
