Sodium cyanide hazards to fish and other wildlife from gold mining operations Sodium cyanide hazards to fish and other wildlife from gold mining operations
Highly toxic sodium cyanide (NaCN) is used increasingly by the international mining community to extract gold and other precious metals through milling of high grade ores and heap leaching of low grade ores. Of the 98 million kg cyanide (CN) consumed in North America in 1989, about 80% was used in gold mining (Knudson 1990). In Canada, more than 90% of the mined gold is extracted from...

Chlorinated hydrocarbons in livers of American mink (Mustela vison) and river otter (Lutra canadensis) from the Columbia and Fraser River Basins, 1990-1992 Chlorinated hydrocarbons in livers of American mink (Mustela vison) and river otter (Lutra canadensis) from the Columbia and Fraser River Basins, 1990-1992
We investigated chlorinated hydrocarbon contaminants in aquatic mustelid species on the Fraser and Columbia Rivers of northwestern North America. Carcasses of river otter (Lutra canadensis) (N=24) and mink (Mustela vison) (N=34) were obtained from commercial trappers during the winters of 1990–91 and 1991–92. Pooled liver samples were analyzed for organochlorine pesticides...

Butyltin compounds in river otters (Lutra canadensis) from the northwestern United States Butyltin compounds in river otters (Lutra canadensis) from the northwestern United States
Butyltin compounds, including mono-, di-, and tributyltin (MBT, DBT, and TBT) were measured in livers of 40 adult river otters (Lutra canadensis) collected from rivers and coastal bays in Washington and Oregon, USA. Butyltins were found in all the river otters, at a concentration range of 8.5–2,610 ng/g, WW. The greatest concentration of total butyltins of 2,610 ng/g, WW, was found in a...

Persistence of high lead concentrations and associated effects in Tundra Swans captured near a mining and smelting complex in northern Idaho Persistence of high lead concentrations and associated effects in Tundra Swans captured near a mining and smelting complex in northern Idaho
Lead poisoning of waterfowl, particularly tundra swans (Cygnus columbianus), has been documented in the Coeur d'Alene River Basin in northern Idaho for nearly a century. Over 90% of the lead-poisoned tundra swans in this area that were necropsied have no ingested lead shot. Spent lead shot from hunting activities over the years is therefore a minor source of lead in these swans. The...

Osprey (Pandion haliaetus) eggs were collected from 1991 to 1997 at nests (n = 121) upstream and downstream of bleached kraft pulp mills and at reference sites in the Fraser and Columbia River drainage systems of British Columbia, Washington, and Oregon. Blood samples were collected from nestling ospreys during the 1992 breeding season on the Thompson River. Samples were analyzed for

Organochlorine pesticides, PCBs, and mercury in Osprey (Pandion haliaetus) eggs from the Upper Volga River, Russia Organochlorine pesticides, PCBs, and mercury in Osprey (Pandion haliaetus) eggs from the Upper Volga River, Russia
The Osprey population associated with Darwin Nature Reserve and the Rybinsk Reservoir increased from only a few pairs prior to the creation of the reservoir in the late 1940s , to about 45-50 pairs in 1994. Productivity rates were excellent in 1988 and 1989 (1.38 young/occupied nest), but extremely low in 1987 (0.47 young/occupied nest). A chemical spill into the Volga River in early...

Declining ring-necked pheasants in the Klamath Basin, California: I. Insecticide exposure Declining ring-necked pheasants in the Klamath Basin, California: I. Insecticide exposure
A study of organophosphorus (OP) insecticide exposure was conducted on a declining population of ring-necked pheasants (Phasianus colchicus) associated with agricultural lands at Tule Lake National Wildlife Refuge (TLNWR) during the summers of 1990–92. Findings at TLNWR were compared with a nearby pheasant population at Lower Klamath National Wildlife Refuge (LKNWR) not subjected to...

Organochlorine pesticides, PCBs, and mercury in hawk, falcon, eagle, and owl eggs from the Lipetsk, Voronezh, Novgorod and Saratov regions, Russia, 1992-1993 Organochlorine pesticides, PCBs, and mercury in hawk, falcon, eagle, and owl eggs from the Lipetsk, Voronezh, Novgorod and Saratov regions, Russia, 1992-1993
Fifty-two eggs (one per nest) of 12 species of raptors were collected in 1992-93 for contaminant analysis in three southern European locations in Russia. One Peregrine Falcon (Falco peregrinus) egg was also collected farther northwest in the Novgorod region. A high DDE concentration (27.3 ppm, wet weight [w/w]) in the Peregrine Falcon egg raised concern for the species in European Russia...
