Arsenic concentrations in lake sediments in the Yellowknife region, Northwest Territories, Canada are elevated from the weathering of mineralized bedrock and/or from the mining and processing of arsenic (As)-bearing ores at legacy gold mines in the area. Specifically, 50 years of ore roasting at Gia...
