1. Quantifying and reducing uncertainty in model calculations of global pollution fate

The main objective of the project is to describe quantitatively with model calculations the global distribution behaviour of persistent organic contaminants, and to establish credibility in the results of these simulations.

2. Spatial and long-term trends in organic contaminants and metals in fish species important to the commercial, sports, and domestic fisheries of Great Slave Lake and the Slave River ecosystem.

i. Determine mercury, metals and persistent organic contaminant pollutants (POPs) concentrations in lake trout harvested from two locations (West Basin near Hay River, East Arm at Lutsel K’e) and burbot harvested from one location (West Basin at Fort Resolution) in 2015 to further extend the long-term (1993-2013 (POPs) and 1993-2014 (mercury)) database. ii. Determine POPs trends in lake trout and burbot using our 1993-2014 data base. iii. Continue our investigations of mercury trends in predatory fish to include lakes in the Deh Cho, Great Bear Lake, and other lakes as opportunities arise. iv. Participate in and contribute information to AMAP expert work groups for trend monitoring for POPs and mercury. v. Integrate our mercury trend assessments with studies we are conducting in the western provinces as part of Canada’s Clear Air Regularly Agenda for its Mercury Science Assessment. vi. Work with communities in capacity building and training.

3. Yukon Traditional Foods Monitoring Program

Short Term i) to provide additional information for use in updating health advisories. Long Term i)to investigate the fate and effects of contaminant deposition and transport to the Yukon, allowing Northerners to better manage the issue of contaminants. ii)to determine levels of contaminants for use in long term trend monitoring.

4. An investigation of factors affecting high mercury concentrations in predatory fish in the Mackenzie River Basin.

1. Continue to investigate spatial and temporal patterns in mercury concentrations in fish in lakes in the Mackenzie River Basin with a focus on predatory fish in smaller lakes near Fort Simpson but also including Great Bear Lake 2. Assess temporal trends in mercury concentrations and influencing factors, e.g., climate change 3. Conduct sediment core studies as opportunities allow to characterize long-term trends in mercury deposition and productivity 4. Integrate the findings of this study with our mercury trend monitoring in Great Slave Lake and the western provinces.

5. The Seasonal Cycle of Organochlorine Concentrations in the Canadian Basin

In September 1997, the CCGS Des Groseillers was frozen into the permanent ice-pack and started a year-long science program drifting across the southern Canada Basin. This program provided a unique opportunity to carry out a "vertical" food-chain study in a seasonal context to learn how the physical and biological systems couple to produce contaminant entry into the food web (Figure 1). "Vertical" components included the water and ice, particles, algae, zooplankton (sorted by trophic level), fish and seal.. The interpretation of contaminant data collected during SHEBA will provide information about the relationship between seasonal ice formation and melt, seasonal atmospheric transport and water column organochlorine concentrations in the Canada Basin. In addition our contaminant sampling program was integrated within a larger science plan where other SHEBA researchers studied the physical and biological properties of the water column. This means that contaminant distributions can be interpreted and modeled within the full context of physical, chemical and biological processes, and of atmospheric and oceanic transport mechanisms.

6. Northern Contaminants Air Monitoring: Organochlorine Measurements

The objectives of this project are: A) to determine whether atmospheric concentrations and deposition of priority pollutants in the Arctic are changing in response to various national and international initiatives by: i) continuing to measure the occurrence of selected organochlorines in the arctic atmosphere at Alert, NWT for a period of three more years (measurements started in 1992), in parallel with identical measurements in western Russia at Amderma; ii) sampling at the Kinngait (Cape Dorset) station in 2000/2001 for the purpose of detecting change in the eastern Canadian Arctic by comparison with observations made four years earlier (1994-1996) at this site; and iii) analyzing and reporting data from Alert, Tagish, Kinngait and Dunai Island thereby providing insight into pollutant trends and sources. B) Ensuring the effective utilization of information at the international negotiating table in order to achieve the appropriate restrictions on release of pollutants of concern for the arctic environment by: i) contributing to the next assessment arising from the second phase of the Northern Contaminants Program (Canada) and specifically, the revised Assessments on POPs and Heavy Metals as part of the Arctic Monitoring and Assessment (AMAP) Program Work Plan; and ii) advising Canadian negotiators in preparing reasonable, practical strategies of control.

7. Fluxes of Mercury from the Arctic Ice Surface during Polar Sunrise Conditions and Melt Conditions

The objectives of this project are: A) to determine the pathway for the transfer of mercury in snowmelt to sea water during the melt period at Alert; B) to determine the extent of open water and wet ice in the summer Arctic as it affects the surface exchange of Hg using satellite radar imagery; and C) to determine the atmospheric dynamics associated with the photochemistry of mercury episodically during the polar sunrise period.

8. Global Gridded gamma-HCH and Endosulfan Emission Inventories

The aim of this project is to compile information and create a computerized database of historical and present global lindane and endosulfan usage data as well as emission data for gamma-hexachlorocyclohexane (gamma-HCH) and endosulfan with 1 degree x 1 degree lat/long resolution. The objectives of this project are: A) to create global gridded g-HCH and endosulfan emission inventories; B) to study the linkage between global g-HCH and endosulfan use trends and g-HCH and endosulfan concentration trends in the Arctic; and C) to assist in comparing concentrations and ratios of different HCH isomers in the Arctic biotic and abiotic environments.
