Legacy arsenic pollution in Yellowknife Bay sediments: An assessment of its long-term fate under a changing climate
chercheur principal: Chételat, John
Année(s) de permis: 2019 2018
Résumé: This study will assess the present-day and future stability of legacy arsenic contamination stored in Yellowknife Bay sediments that originated from local gold mining activities. Using a combination of quantitative methods (field measurements, laboratory experiments, paleolimnology and mass balance modelling), the research team will estimate the diffusion of arsenic from sediments to overlying wat...

Cumulative Impacts Monitoring of Aquatic Ecosystem Health of Yellowknife Bay, Great Slave Lake
chercheur principal: Chételat, John
Année(s) de permis: 2015
Résumé: The main objective of this study is to investigate the ecosystem health of Yellowknife Bay. We will address the following questions through a field study: 1) What is the quality of water and sediment in Yellowknife Bay (focusing on metals, nutrients and cyanobacteria)? 2) What are the main sources and transport pathways of metals accumulating in the food web of Yellowknife Bay? 3) How much of ...

Cumulative impacts of metal deposition in the NWT: Using lead isotopes to trace local, regional and long-range sources
chercheur principal: Chételat, John
Année(s) de permis: 2014 2013
Résumé: Yellowknife Bay on Great Slave Lake is a water body of cultural, subsistence and recreational importance for the Yellowknives Dene First Nation (YKDFN) and residents of Yellowknife. The ecosystem health of Yellowknife Bay has been impacted by historical mining releases of metals (particularly arsenic), as well as long-range atmospheric transport of metals such as mercury from far-away human emissi...
