Distinguishing between natural and anthropogenic sources of arsenic in soils from the Giant mine, Northwest Territories and the North Brookfield mine, Nova Scotia
Anthropogenic and geogenic sources of arsenic (As) have been identified in mining-impacted soils from the Giant mine (1948-1999), NT and the North Brookfield mine (1886-1906), NS. Both used roasting to extract gold from ...
Hydrogeochemical Evaluation and Impact of Remediation Design on Arsenic Mobility at Historical Gold Mine Sites
Historical gold mine tailings at several sites in Nova Scotia, Canada are publicly accessible and may pose a threat to human and ecosystem health because of high arsenic (As) concentrations in the tailings (max 25 wt.%) ...
ARSENIC SPECIATION AND THE CONTROLS ON ITS RELEASE IN CONTAMINATED SEDIMENTS AND CORRESPONDING TOXICOLOGICAL EFFECTS AT GIANT MINE, NWT
Arsenic (As) contamination presents an ecosystem and human health risk at Giant Mine, a historic gold mine near Yellowknife, NWT currently undergoing the final stages of assessment for remediation. Arsenic concentration ...
Dynamic Arsenic Cycling in Scorodite-Bearing Hardpan Cements, Montague Gold Mines, Nova Scotia
Hardpans, or cemented layers, form from precipitation and subsequent cementation of secondary minerals in mine tailings and can act as both physical and chemical barriers. During precipitation, metals in the tailings are ...
