Wildfires and contaminated landscapes: The impact of wildfire on the mobility, transport and fate of metal(loids) in a subarctic shield landscape
Principal Investigator: Devoie, Élise
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5898. The main goal of this project is to explore how wildfire will affect the stability and fate of metals and metalloids (i.e. arsenic, mercury, antimony) in mining contaminated and pristine landscapes. Metal(loid) concentrations in air, soil, and water in and around Boundary Creek (30 km west of Yellowknife) will be co...


A multidisciplinary investigation of recovery in Yellowknife area lakes from 50 years of arsenic pollution: What are the factors inhibiting recovery and the biological consequences?
Principal Investigator: Palmer, Mike
Licensed Year(s): 2019 2018 2017
Summary: The overarching objectives of this research are two-fold: 1)To investigate watershed and within-lake abiotic processes affecting the recovery of mine-impacted lakes in the Yellowknife area, including storage and release of arsenic from soils, seasonal dynamics of arsenic export in runoff, and fluxes of arsenic to and from lake sediments; and 2) To investigate the toxicological consequences of ...


Developing New Tools for Assessing Legacy Pollutants and their Ecological Consequences in Lakes Near Northwest Territories Mines
Principal Investigator: Blais, Jules M
Licensed Year(s): 2017 2016 2015
Summary: The research team propose to develop tools to assess risks associated with legacy industrial developments in a northern setting. The team will investigate contaminants from the Giant Mine near Yellowknife Northwest Territories (NT), which operated between 1948 and 2004, producing a legacy of contaminants including arsenic, antimony, hydrocarbons, mercury, and others. This remediation strategy appl...


Arsenic speciation in Yellowknife Lakes during spring bloom
Principal Investigator: Reimer, Kenneth J.
Licensed Year(s): 2010
Summary: The objectives of this research are to: 1. Determine total arsenic and arsenic species in water from Kam Lake and Meg Lake, 2. Determine total arsenic and arsenic species in porewater (which is a link between sediments and overlying water) from Kam Lake and Meg Lake, 3. Determine plankton communities, and total arsenic and arsenic species in plankton fractions, 4. Determine arsenic in food sou...
