2009 Résumé:
The objective of this research is to investigate metals levels, particularly lead and zinc, and hydrocarbons in soils near the old CN rail bed to Pine Point mine, and Highway 5 to the Tamerlane R-190 advanced exploration site. Specific objectives are to 1) Determine levels of metals, particularly lead and zinc, and hydrocarbons on and adjacent to the old CN railbed; 2) Establish levels of metals, ...

2003 Résumé:
The purpose of the study is to have Aboriginal participation in monitoring programs at the Diavik site; to assess the quality of fish for eating – records of fish taste, smell and texture from fish caught in Lac de Gras; collection of fish tissue samples to analyze for metals concentrations; collection of fish otoliths to determine age of fish; focus on sampling fish of similar size/age in order t...

2009
Résumé:
This licence is being issued for the scientific research application no.1050.
The objectives of this research are to: 1. collect 15 lake trout, 15 whitefish and 15 herring for analysis of metals, including mercury, radionuclides and organochlorine pesticides; 2. compare the levels of the compounds with the same species near the mines in the eastern part of Great Bear Lake.
Fish will be colle...

2007
Résumé:
The objectives of this research are two-fold:
1) Identify an ecological indicator that can monitor changes in loadings of metals in the South Nahanni Watershed. This work is scheduled for completion in 2007-2008.
2) Establish a monitoring program that can quantify the cumulative effects of mining activities on the health of streams in the South Nahanni Watershed. This work is scheduled for compl...

2007
Résumé:
The monitoring objectives of this project are: to conduct a targeted scientific program to analyze heavy metals and trace elements and stable isotopes in vegetation (caribou food); to correlate the results in vegetation with concentrations in caribou from a related NCP program [Gamberg 2006]; to test if contaminant patterns in caribou tissues will vary with patterns observed in lichen/moss, or wil...

Résumé:
This is a study investigating the contaminant levels in sea-run Arctic char as they return from feeding in the ocean. The aim of this study is to provide communities with more information on the chemical levels in these fish. By making these chemical measurements in char and comparing them with chemical levels in marine mammals, there would be a possibility to demonstrate that char is a good food ...

Résumé:
In this project four test-scale piles will be studied, two composed of rock from the diamond mine site, and two composed of mine rock with reclaimation covers placed on the top. Under study are the hydrology of the piles, the release of metals by sulfide oxidation and the attenuation of these metals through the formation of secondary minerals. The concentrations of oxygen and carbon dioxide in the...

2004 Résumé:
The researchers will measure water quality, aquatic ecology and the status of fish populations in ponds and lakes along the proposed discharge route of mine water from the Colomac Mine (North Pond, L-Shaped Lake, Paddle Lake, Lake 315, and Lower Lake) and compare those data with data collected from reference lakes (Steeves Lake, Baton Lake, and Spanner Lake). Work will include taking three samples...

Résumé:
Currently, there is no information about the bioavailability and toxicity of metals in the Slave River delta. The goal of this research is to examine metal cycling pathways in the delta and to assess the role of aquatic vegetation for metal accumulation...
