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 will 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 NT, which operated between 1948 and 2004, producing a legacy of contaminants including arsenic, antimony, hydrocarbons, mercury, and others. This remediation strategy only applies to the Giant Mine pro...

Impacts of recent climate warming on Canada’s northern aquatic ecosystems
Principal Investigator: Blais, Jules M
Licensed Year(s): 2014
Summary: The objectives of this research project are: 1) to determine the impact of shoreline expansion and forest/peat submergence from thawing permafrost on contaminant and carbon fluxes to lakes in the Yellowknife region; 2) to develop novel approaches to track terrestrial organic matter sources in lakes, in order to assess how climate warming and permafrost thaw are affecting the delivery of terrestr...

The Arctic in Flux: How has Recent Climate Change Affected Contaminant Transport and Uptake in Aquatic Arctic Systems?
Principal Investigator: Blais, Jules M
Licensed Year(s): 2013 2012
Summary: This research will determine how the recent and dramatic climate changes in Arctic freshwater have affected the transport and fate of anthropogenic contaminants to freshwater systems, two of the largest threats facing northern communities and ecosystems. This research will develop new tools to examine how the fate of anthropogenic contaminants is affected in Arctic regions under different climate ...

Enhanced Contaminant Transport from Thawing Permafrost in Freshwater Ecosystems
Principal Investigator: Blais, Jules M
Licensed Year(s): 2010
Summary: This research goal is to examine the role of thermokarst development on natural organic matter and the release of metals (e.g. mercury) and organic contaminants (e.g. polychlorinated biphenyls - PCBs). Sampling for contaminants: Water sampling for persistent organic pollutants (POPs) will be done by passive samplers, consisting of a semi-permeable membrane containing a resin that will extract ...
