Why is Mercury rising in some northern lakes and not others?
chercheur principal:
Année(s) de permis: 2025
Résumé: This licence has been issued for the scientific research application No. 5927. We will leverage a large spatial dataset of over 200 near-surface lake sediment samples in the central Northwest Territories to better understand controls on biogeochemical cycling of Hg and other elements of concern, and analyze lake sediment and peat cores to obtain a temporal perspective of metal(loid) accumulatio...


Murky waters: Impacts of disturbances on the mobilization and downstream delivery of mercury and methylmercury
chercheur principal:
Année(s) de permis: 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No.5448. This project proposes to monitor wetlands, streams, rivers, and lakes in the Dehcho region, with a focus on understanding current and future trends in aquatic mercury and methylmercury. The region has vast stores of mercury accumulated in organic wetland soils, and there is a risk that disturbances such as permafrost ...


Further Examination of the Bio- Magnification of Mercury within Fish Species and watersheds of the Deh Cho and Their Varying Levels Among Lakes
chercheur principal:
Année(s) de permis: 2024 2023 2021 2019
Résumé: This licence has been issued for the scientific research application No.5348. The objectives of this research project are: 1) to determine why fish mercury levels vary among lakes in the Dehcho region; 2) to identify best predictors of fish mercury levels; 3) to determine with fish have the lowest levels of mercury and the highest levels of nutrients; and, 4) to collect data on parameters that ...


Contaminant Biomonitoring in the Northwest Territories Mackenzie Valley: Investigating the Links Between Contaminant Exposure, Nutritional Status, and Country Food Use
chercheur principal:
Année(s) de permis: 2017 2015 2014
Résumé: The overall objective of this research is to promote country foods in the Dehcho Region in a way that balances contaminant risks and nutrient benefits in order to maximize nutrient status while minimizing mercury exposure. The research team will work towards this objective through the implementation of research that will consist of the biomonitoring study to evaluate country food usage patterns, c...

Updating data on mercury levels in food fish species in lakes used by Deh Cho communities
chercheur principal:
Année(s) de permis: 2016 2015 2014 2012 2011
Résumé: The objectives of this project are: 1) to determine through which lakes are important as food sources in four Dehcho communities and which fish species are used for human food from these lakes; 2) to train community monitors to collect fish and other samples according to Environment Canada and Department of Fisheries and Oceans protocol; 3) to involve local school children in the studies by ...
