Summary: Given the threats of polybrominated diphenyl ethers (PBDEs) and their widespread appearance in marine mammals and far northern communities, identifying the sources of these compounds and of various PBDE congeners in air, water and soil are of utmost importance. Potential ecological and human health risks, and increasing concentrations of PBDEs in the environment require early implementation of con...

Summary: PFOA is a synthetic compound documented as being widely dispersed in the environment, including in biota of high-northern latitudes. The route of this dispersal is not entirely clear. PFOA concentrations in soil samples from several locations around the world will be analyzed to determine environmental reservoirs and global distribution. Two new 250-ml HDPE sample bottles will be shipped to Auro...

Summary: This project aims to address a local concern about the release of contaminants resulting from an enduring fire at the Inuvik dumpsite by complementing the monitoring of Inuvik’s dumpsite for non-standard contaminants, and by reaffirming the drainage pathways from the dumpsite. Water samples (40-80 l) will be collected from two streams that clear the melt water from the dumpsite area, and the t...

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...

Summary: Since the 1970s, the oil and gas industry has drilled at least nineteen exploratory wells in the Kendall Island Bird Sanctuary. Observations at associated drilling mud-sumps have been made; however, there remains a paucity of field data describing site conditions. It is also appreciated that construction of the proposed Mackenzie Valley pipeline will stimulate the development of Niglintgak and Tag...

Summary: The research team will collect data to assess environmental conditions at well sites and sumps abandoned during the 1970s and 1980s, and in nearby undisturbed terrain in the Kendall Island Bird Sanctuary (KIBS). Study site locations include: Taglu D-43, Taglu H-54, Taglu C-42, Niglintgak B-19, Kumak K-16, Kumak E-58 and Kumak J-06. Permafrost investigations will take place in the surrounding terr...

Summary: This is a continuation of the ISR exploratory fishery initiated in 2003. The program is part of a larger experimental fishery investigation aimed at providing information required to assess the potential of initiating small-scale, community-based commerc...

Summary: There are three objectives for the evaluation of historic sumps during this project. The first objective is to field verify the "Protocol for the Assessment of Drilling Mud Sumps” for evaluating historic sump site locations. The second objective is to identify, inventory, and assess the environmental conditions at the historic sump sites, and the third objective is to compile consistent data on ...

Summary: This study is looking at the contaminant levels in lake trout and burbot in Great Slave Lake and in arctic char after their return from feeding in the ocean. Twenty burbot and twenty lake trout will be collected from the West Basin of Great Slave Lake by...

Summary: In the Mackenzie Delta region, many of the drilling mud sumps constructed in the 1970s have partially or completely collapsed. The collapse of a sump can release contaminants previously immobilized in permafrost. The long-term degradation of many sumps...
