Seal Diet and Condition in the ISR
Principal Investigator: Insley, Stephen J
Licensed Year(s): 2019 2018
Summary: The goal of this project is to design and maintain a long-term, locally-based, diet and condition data collection program focused on ringed seals (Pusa hispida) and bearded seals (Erignathus barbatus) in the Darnley Bay and Ulukhaktok areas of the Inuvialuit Settlement Region (ISR). To accomplish the objectives, the research team have designed a program to work with the local communities of Pau...

EBA, Five Mine Sites ESA Update and Remedial Action Plan
Principal Investigator: Farrell, Rory
Licensed Year(s): 2012
Summary: To take specific samples for the completion of a remedial action plan and risk assessment for the Five Mine Sites. The field component of the project will be conducted over a two day period. Limited soil and mine tailing samples from the most contaminated areas of the site will be taken. These areas were previously identified in past environmental site assessments. The samples will be collec...

An investigation of arsenic speciation and toxicity in Baker Creek sediments from Giant Mine in the Northwest Territories, Canada
Principal Investigator: Nash, Tyler J
Licensed Year(s): 2012
Summary: The objective of this research project is to assess the sediment quality of Baker Creek. This will be achieved by analyzing factors influencing arsenic mobility from sediments to overlying water and assessing the toxicology of the sediments using exposure tests on indicator organisms. Core samples of Baker Creek sediments will be taken by the researchers using aluminum pipes driven into the gro...

Investigation into the occurrence of abnormal loche livers in the Gwich'in Settlement Area (GSA), Northwest Territories
Principal Investigator: Thompson, Amy L
Licensed Year(s): 2008 2007
Summary: This research entails a thorough literature search of all the available literature on loche livers and pathology, and an investigation into the occurrence of abnormal loche livers by field sampling and pathology analysis. A local fisher will be hired from each community (Inuvik, Aklavik, Tsiigehtchic and Fort McPherson) to collect loche. A Gwich’in Renewable Resources Board (GRRB) biologist an...

The Reproductive and Developmental Toxicity of Arsenic in Mine Waste Soils on the Earthworm (Eisenia fetida andrei)
Principal Investigator: Wong, Stephen
Licensed Year(s): 2001
Summary: The research team will examine soils which will be collected by DIAND Contaminants Division staff from Yellowknife. Approximately 20 kg of contaminated soil will be collected from a site close to the Con Mine. As well, approximately 80 kg of uncontaminated soil (for use as a reference soil) will be collected from a site adjacent to the Rae Highway. All soils will be returned to a laboratory at ...

1996 Field Evaluation of Aquatic Effects Monitoring Methods to Determine Mining Effects
Principal Investigator: Chapman, Peter M.
Licensed Year(s): 1996
Summary: The Lupin study site is one of seven mine sites being investigated across Canada. Receiving water samples will be collected for chemistry (total and dissolved metals) and toxicity testing. To ensure that a well-defined chemical gradient exists water and sediment will be collected from reference and exposure stations at the study site. Sediment samples will be collected for chemistry (total orga...

Methods development of acute toxicity testing using marine invertebrates from the Canadian arctic.
Principal Investigator: Gandia, Ruben
Licensed Year(s): 1993
Summary: Clean and contaminated sediments, effluent and liquid municipal waste, and selected species of amphipods will be collected by government and non-government researchers as other field research is conducted. All collections will be shipped to the Beak laboratory for analyses. Testing will involve a measurement of the contaminants in the sediments as well as measuring the degree of toxicity that th...

Food Composition and Dietary Evaluation for Nutrients and Environmental Contaminants in Mackenzie Zone
Principal Investigator: Kuhnlein, Harriet V
Licensed Year(s): 1990
Summary: Dr. Kuhnlein and her team will study the foods in the traditional food system of the Dene people of Fort Good Hope/Colville Lake for their composition and patterns of use. Nutritional properties as well as toxicological properties will be assessed. Household and personal food use interviews previously collected will be analyzed using nutrient and toxicology data of food samples from the Dene area....
