Spatial and long-term trends in persistent organic contaminants and metals in lake trout and burbot from the Northwest Territories
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004
Summary: The purpose of the study is to continue investigating whether contaminant levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which the research team has been studying since the early 1990s. The plan is to collect lake trout from Great Slave Lake (Hay River area and Lutsel K’e area). The research team also plans to collect burbot from the Lutsel K’e and Fort R...


Temporal trends and spatial variations in persistent organic pollutants and metals in sea-run char from the Canadian Arctic
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2007 2006
Summary: 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 ...


Surficial Geology Mapping Fort Norman (96C), Blackwater Lake (96B), Mahoney Lake (96F)
Principal Investigator: Duk-Rodkin, Alejandra ADR
Licenced Year(s): 2003
Summary: This project aims to obtain a better understanding of the sensitivity of slopes to disturbance from development, especially in the context of progressive climate warming. It will also identify baseline levels for natural and anthropogenic contaminants,...


Investigation of factors affecting high mercury levels in fish in lakes in the Mackenzie River Basin (2002-2003)
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2003 1998
Summary: This study is based on earlier research conducted by the Department of Fisheries and Oceans which found that fish in many lakes in the Mackenzie River Basin had high mercury concentrations. This study examines the environment in which the fish live in o...


2002 Baseline Air Quality Volatile Organic Compound (VOC) Monitoring Program in the Taglu and Parsons Lake Production Areas
Principal Investigator: Povey, Andrew
Licenced Year(s): 2002
Summary: Imperial Oil Resources, Aboriginal Pipeline Group, Conoco Canada Resources Ltd, Shell Canada Ltd, and ExxonMobil Canada initiated a number of Biophysical Baseline Studies during 2001 as part of a feasibility study for the Mackenzie Gas Project. This pro...


Persistent organic contaminants in the Great Slave Lake ecosystem.
Principal Investigator: Evans, Marlene S
Licenced Year(s): 1995 1994
Summary: The researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Fort Resolution and Lutsel K'e. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect invertebrates and fish samples as part of an overall study of contaminants in the lake's ecosystem....


Assessment Of Effects Of Preparation On Levels of Organic Contaminants In Inuit Traditional Food.
Principal Investigator: Chan, L.H.M.
Licenced Year(s): 1994
Summary: The project is to see how different organic contaminants change with different preparation methods of the important fatty foods used by the Inuit. The research will focus on food prepared for eating. Samples (aprox. 120) will be collected and prepared by a research assistant from the community. The study aims to find the best ways to prepare these food items to reduce exposure to these contamin...


Amituk Lake: Trace Organic Contaminants in an Arctic Aquatic System
Principal Investigator: Semkin, Raymond
Licenced Year(s): 1994
Summary: Amituk Lake and the east coast of Cornwallis Island is a research site for documenting the occurence and movement of organic and inorganic contminants from winter snowpack into a freshwater lake. Numerous tests for snowpack water content and chemistry are carried out before snowmelt begins. Chemical and flow measurements are also taken at 6 streams and the lake outlet....


Contaminant deposition measurements in precipitation in the NWT
Principal Investigator: Gregor, Dennis J.
Licenced Year(s): 1994 1993
Summary: There is only limited information on contaminant trends in arctic ecosystems. This long-term study is examining the amounts of contaminants present in arctic ice caps. By taking core samples from ice caps, the researchers are able to measure the levels of contaminants that have been deposited by precipitation over many years. This study will also improve our understanding of the levels of conta...


Atmospheric transport of organic contaminants
Principal Investigator: Waite, Don
Licenced Year(s): 1993
Summary: In this study, we will collect air, dust and rain samples on a weekly basis at five Canadian locations during the months of June and July, 1993. Three locations are in the NWT while two locations are in Saskatchewan. The samples will be analyzed in Regina and Edmonton for the presence of certain insecticides, herbicides and PCB's that are known to be transported in the atmosphere....
