Understanding the potential impacts of rare earth elements in aquatic systems in the NWT.
chercheur principal: McGeer, Jim
Année(s) de permis: 2023 2022
Résumé: This licence has been issued for the scientific research application No.5300. The objectives of the project are to develop data on the aquatic toxicology of rare earth elements in northern ecosystems and to contribute to water quality criteria for these metals. Three types of sample collections are proposed: 1) Water samples of approximately 0.5 L will be collected in pre-cleaned bottles ...


Understanding the potential impact of metals in aquatic systems.
chercheur principal: McGeer, Jim
Année(s) de permis: 2017
Résumé: The objectives of this research are to evaluate the relative sensitivity of northern aquatic invertebrates and northern ecosystems in comparison to southern species and environments. The focus of comparisons is in relation to the toxicity of metals. Three types of sample collections are proposed. These would be done at selected sites along the Ingraham Trail (highway 4) east of Yellowknife. The...


Understanding Community Based Monitoring Exceedances Through Site Assessments
chercheur principal: McGeer, Jim
Année(s) de permis: 2016
Résumé: The objectives of this project are to apply short term sublethal exposures to contaminants of concern with locally collected small bodied fish to establish measures of the relative bioavailability and effect in the Slave River. This information will then be applied to the Community Based Monitoring (CBM) program data to assess exceedances in a more comprehensive manner. Small fish (for exampl...
