Abundant reserves of metals and oil have spurred large-scale mining developments across
northwestern Canada during the past 80 years. Historically, the associated emissions …

Climate change is profoundly affecting seasonality, biological productivity, and hydrology in
high northern latitudes. In sensitive subarctic environments exploitation of mineral resources …

The controls on the mobility and fate of arsenic in lakes impacted by historical gold ore
roasting in northern Canada have been examined. A detailed characterization of arsenic …

Ore processing techniques used in Yellowknife's largest mining operation, Giant Mine, is
responsible for the atmospheric release of approximately 20,000 t of particulate arsenic …

Gold mines in the Yellowknife, NT, region—in particular, the Giant Mine—operated from
1949–99, releasing 237,000 tonnes of waste arsenic trioxide (As2O3) dust, among other …

Arsenic (As) concentrations in lake sediments in the Yellowknife region, Northwest
Territories, Canada, are elevated from the weathering of mineralized bedrock and/or from …

The contributions of contaminant sources are difficult to resolve in the sediment record using
concentration gradients and flux reconstruction alone. In this study, we demonstrate that …

Precious metal mining activities have left complex environmental legacies in lakes around
the world, including some sites in climatically sensitive regions of the Canadian sub-Arctic …

Gold mining operations near Yellowknife (Northwest Territories, Canada) released vast
quantities of arsenic trioxide during the 1950s, which dispersed across the landscape …

Contaminant levels in fish are of public concern in northern Canada where they are an
important food source. In this study, we investigated the concentration of total arsenic, four …
