Monitoring Temporal Trends of Human Environmental Contaminants in the NWT and Nunavut
Principal Investigator: Beveridge, Christopher
Licenced Year(s): 2006 2005
Summary: The overall goal of this program is to establish a time trend of specific environmental contaminants in human blood and hair. A baseline study was completed in the Inuvik region in 1999–2000. A follow-up assessment to this baseline study will be undertaken this year to observe human exposure to specific contaminants across a representative cross-section of moderately and highly exposed regions (In...


Inuvik Regional Human Contaminants Monitoring Program
Principal Investigator: MacNeil, Chuck
Licenced Year(s): 2000 1999 1998
Summary: The Inuvik Regional Human Contaminants Monitoring Program has finished sampling maternal scalp hair for methyl mercury analysis, and checking maternal and umbilical cord blood for certain organochlorines and metals. The communications phase is now beginning. As of March 2000 participants will have the option to review their medical health records and obtain their personal results. The compiled res...


Environmental Study of Abandoned DEW Line Sites.
Principal Investigator: Reimer, K.J.
Licenced Year(s): 1994 1993
Summary: The researchers will collect soil/sediment, water, plant and other biological samples to investigate small-scale variations of introduced substances; to examine larger variations in tundra and marine ecosystems; and to aid decision-makers in identifying when and where remedial measures can be most effectively applied. This investigation will be conducted on abandoned DEW Line sites to evaluate th...


Human Contaminant Trends in Arctic Canada (Cord Blood Monitoring)
Principal Investigator: Seddon, Laura
Licenced Year(s): 1995 1994
Summary: This activity will help expand the human health baseline on exposure and effects of environmental contaminants on humans in the NWT. Blood will be sampled from participating mothers and from the umbilical cord to determine the levels of specific organochlorines and heavy metals. This activity will involve the participation of communities and community health workers in all aspects including desi...


Latitudinal patterns of organochlorine contamination in zooplankton
Principal Investigator: Koenig, Brenda
Licenced Year(s): 1993
Summary: Organochlorine contaminants can be carried to the arctic in the atmosphere. I will be measuring the amount of these contaminants in zooplankton to determine the effects and range of organochlorines in the arctic ecosystem. The information that I collect will be useful in determining what types of organochlorines are most common in zooplankton as well as providing a means to estimate the levels o...


Investigations of presence and concentration of chlorinated organic industrial compounds and pesticides in lake sediment and fish from lakes of the Belcher Islands
Principal Investigator: Hermanson, Mark
Licenced Year(s): 1994 1993 1992 1990
Summary: We will collect and analyze sediments and fish collected from Imitavik, Annak and Kasegalik Lakes in order to assess the type and levels of contaminants present. Kasegalik Lake contains fish that are considerably different in size that those from other lakes and, since the accumulation of contaminants in fish are related to both the size and the age of the fish, it is possible that fish collected...


Hurwitz-Kaminak geological mapping
Principal Investigator: Aspler, L.B.
Licenced Year(s): 1993 1992
Summary: A field crew of four people will map (by foot and boat) the rocks deposited in ancient (2,500 to 1,900 million year old) basins. These rocks will also be assessed for their economic potential. The field work will also involve the collection of water, moss and lichen to determine levels of contaminants as part of the northern contaminants study funded by the Arctic Environmental Strategy....


Contaminant analyses for wildlife food sources in the Inuvialuit Settlement Region
Principal Investigator: Bell, Bob
Licenced Year(s): 1993
Summary: This project was initiated following the concern voiced by the six ISR communities about the presence and levels of contaminants in the major country food sources. Samples of body tissues will be taken from charr, whitefish, seals and belugas in order to assess for heavy metal, organochlorine and PCB contaminants. These samples will be taken while other field research is being conducted by Fishe...


Toxaphene in the Arctic: Atmospheric Delivery and Transformation in the Food Chain
Principal Investigator: Bidleman, Terry F.
Licenced Year(s): 1992
Summary: The researcher will collect air and water samples for analysis of toxaphene and other organochlorine compounds, as well as examining differences in toxaphene patterns in air, water and biological samples....


Organic Contaminants in the Arctic Ecosystem: Utilizing the Ringed Seal (Phoca hispida) as a Biomonitor
Principal Investigator: Metcalfe, C.D.
Licenced Year(s): 1991
Summary: The Research will examine the variation of organochlorine contaminants (O.C.'s) in the arctic ringed seal species. Major trends in concentrations will be outlined on 4 distinct levels: 1) variation within individual seals 2) seasonal variation in one seal popultion 3) variation between seal popultaions from two distinct sites 4) long-term temporal variations at these two locations....
