These samples were collected to determine the occurrence and levels of legacy pesticides and new and emerging priority compounds under the Canadian Chemical Management Plan. Analysis was done by gas chromatograph-mass spectrometer (GC-MSD) and liquid-chromatography mass spec mass spec (LC-MS/MS). The objectives of this project are: 1) to determine current concentrations of priority pollutants to compare with future concentration; 2) to assess how existing and new long-lived pollutants are transported to the arctic, what happens to them once they are there, and how they enter the food web; 3) to assess changes in pollutant levels in the Canadian Archipelago over time and thus determine the effectiveness of Canadian and international regulations to reduce emissions of certain long-lived pollutants; and 4) to understand how climate change influences how these chemicals move in the environment.

One objective of this project is to establish current concentrations of priority pollutants so future concentrations can be compared. Marine traffic, mining and oil/gas exploration is expected to increase in the archipelago and could impact levels of contaminants in air and water. Some of these pollutants include flame retardants, pesticides and chemicals released when burning fuels. Some local sources of these chemicals in the Arctic are from diesel burning for electricity (diesel is burned in Nunavut's 25 hamlets to produce electricity), diesel burning ships, local oil exploration, forest fires and long range transport from southern regions. As other long-lived pollutants decline due to regulations, chemicals from fuel burning may become a more important pollutant in the arctic environment. Another important set of chemicals in the arctic are flame retardants, they are receiving increased attention due to their presence in the arctic environment. Flame retardants are used mainly in furniture, foam, textiles and fire resistant coatings but some are also used in plastics, hydraulic fluids, lacquer/paint, glue and cosmetics. As some flame retardants are banned, the use of other flame retardants will increase. The goal of this work is to determine how existing and new long-lived pollutants are transported to the arctic, what happens to them once they are there, and how they enter the food web. We propose to achieve this through air and water sampling in the Canadian Archipelago in collaboration with the ArcticNet program onboard the Canadian Coast Guard Ship Amundsen. This study will build on air and water investigations conducted by the same team since 1992 but looking at a broader range of chemicals. Results of this research, combined with those from earlier studies, will allow us to assess changes in pollutant levels in the Canadian Archipelago over time. Our monitoring work helps us determine the effectiveness of Canadian and international regulations to reduce emissions of certain long-lived pollutants. Our work also helps us understand how a changing climate influences how these chemicals move in the environment. The information we collect on levels of new chemicals in Arctic air and water, including new flame retardants, will be used to determine whether or not they should be banned world-wide.
