Contaminant deposition measurements in precipitation in the NWT
Principal Investigator: Gregor, Dennis J.
Licensed 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...

Current contaminant deposition measurements in precipitation throughout the NWT
Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1993
Summary: Contaminants are carried in the air to the arctic during the winter when large-scale wind movements bring these contaminants from industrialized locations in North America, Europe and Asia to the north. Snow can collect these compounds from the air and bring them to the ground where they can accumulate. Thus, it is important to study the amount of contaminants in snow to determine the types and ...

Deposition and Fate of Trace Organic Contaminants in Arctic Aquatic Systems
Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1992 1991 1991 1990
Summary: Snow samples will be collected from very remote sites throughout the mainland of NWT during visits to stations maintained by Water Resources Branch. Samples will also be collected at several high Arctic weather stations. Intensive sampling will also be conducted on Agassiz Ice Cap near Resolute. Samples will be analyzed for pesticides, PCBs and other compounds....
