20122011 Summary:
The research team will quantify the effects of exposure of embryonic fish to contaminants released from oilsands operations that may be present in the sediments.
The research team will drill a hole in the ice, no more than 12 inches in diameter, and use sediment collection equipment to collect a few centimeters of sediment from the river bed.
Local communities will have an opportunity to as...

Summary:
Samples of sediment, water and different marine species such as fish, marine invertebrates (including sea urchins, clams and crabs), and microscopic organisms will be collected by divers from the underwater dumpsite in Cambridge Bay. These samples will be assessed for contaminants such as heavy metals and PCB's. The study is primarily being conducted to determine if the waste materials of the du...

Summary:
The researcher plans to take samples of sediments and fish from sites near the three settlements in order to determine the types of contaminants that are present in the environment as well as those that collect or accumulate in the tissues of fish. This study will benefit other studies that have examined contaminants in NWT wildlife as fish are preyed upon by a variety of wildlife species. The r...

19921990 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...

1992 Summary:
As part of this ongoing study, sediment samples will be taken fron the deepest locations of Lac Belot and Colville Lake. These samples will be analyzed for the presence of contaminants and dated. These analyses will allow the researcher to construct histories of the input of contaminants to these lakes. In addition, lake trout, whitefish and burbot will be collected to determine what contaminan...
