Dragonfly mercury monitoring in the Northwest Territories
Principal Investigator: Chetelat, John
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5648. The main objective of this project is to measure mercury in dragonfly larvae from a variety of aquatic ecosystems in the Yellowknife area. This information will be collected as part of a Canada-wide project to evaluate geographic and temporal patterns of mercury bioaccumulation. The first priority will be to inve...

Biochemical and metabolomic impact of trace metals (As, Sb, Cd, Ag, La, Ce) in various fish species and amphipods collected from the metal-impacted Yellowknife area
Principal Investigator: Rosabal, Maikel
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5278. The main goal is to generate a specific knowledge about the implications of metals bioaccumulated observed in the population of three species of fish (e.g., northern pike, lake whitefish, yellow perch) and invertebrates (H. azteca) inhabiting ecosystems located in this mining region. The specific objectives are: 1) to...

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 ...

7 Mine Site Project
Principal Investigator: Widmeyer, Joline
Licensed Year(s): 2010
Summary: The objective of this study is to identify what fish species are in Ruth Lake and Bullmoose Lake and to conduct tissue sampling which will assist in determining if the fish in these lakes are bioaccumulating heavy metals. Fish will be sampled using techniques such as minnow trapping, seining, gill netting, angling and possibly boat electrofishing. Nets and minnow traps may be left at the sam...

Bioaccumulation of Brominated Flame Retardants, Currently Used Pesticides, and emerging metal trends in the Vegetation-Caribou-Wolf Food Chain
Principal Investigator: Katz, Sharon
Licensed Year(s): 2009
Summary: The objectives of this study are: (a) To determine whether brominated flame retardants (BFRs), current use pesticides (CUPs), perfluorinated compounds (PFCs), and mercury bioaccumulate using the vegetation-caribou-wolf food chain and the Bathurst caribou herd as a model; (b) To explore possible sources of lead contamination in the Bathurst herd caribou; (c) To elucidate the pathway of lead uptake ...

Aquatic Studies in support of the Discovery Mine Remediation Work
Principal Investigator: Ford, Bruce S
Licensed Year(s): 2005
Summary: This study involves fish sampling to determine relative abundance and levels of mercury and other metals in fish tissue in Giauque Lake, Thistlethwaite Lake and Control Lake A, as well as benthic invertebrate sampling and water quality sampling in the three lakes to complement the fish sampling. 3 sites in Giauque, 3 in Thistlethwaite and one in Control Lake A will be recorded. Captured fish will ...

Arsenic Speciation in Fish for Back Bay, Yellowknife, and Consequences for Human Health
Principal Investigator: de Rosemond, Simone
Licensed Year(s): 2003
Summary: The Giant Mine, Yellowknife, was in operation for more than 50 years during which time arsenic levels in the surrounding area have significantly increased due to the roasting methods used to extract gold from mined ore. Arsenic was measured in walleye (...

Inuvik Regional Human Contaminants Monitoring Program
Principal Investigator: MacNeil, Chuck
Licensed Year(s): 2000 1999 1998
Summary: This study will serve to establish the types & levels of organochlorines and heavy metals in maternal and cord blood samples, and the level of mercury in hair samples from participants in the area served by the Inuvik Regional & Social Services Board.

Studies on the past, present and future ecological impact on Canadian northern boreal forest and arctic ecosystems due to mining activities, shown at the Great Slave Lake area, Northwest Territories, Canada
Principal Investigator: Steinecke, Karin
Licensed Year(s): 1998 1997
Summary: The project will focus on understanding, analyzing and evaluating the reactions of the northern boreal forest ecosystems in the Great Slave Lake region due to man made stress of mining, settlement and connecting activities. The project will try to develop some general conclusions, statements and model systems. The research team (2 persons) will come from Europe to Yellowknife by plane. The base wi...

Principal Investigator: Thomas, Patricia
Licensed Year(s): 1991
Summary: The study will compare two arctic food chains, namely, lichen-caribou- wolf and lichen-caribou-human to investigate the accumulation and transfer of Polonium-210 and Lead-210.
