61. Heavy Metal and Radionuclide Contaminants in Caribou

Objectives 1. To determine tissue residue levels of metals and radionuclides in caribou given its importance as a country food species. 2. To monitor contaminant exposure in caribou as a representative species of the terrestrial arctic ecosystem. 3. To examine metal speciation and isotopes ratios (uranium, thorium, strontium, titanium) which may provide insight into the source of contamination (anthropogenic vs. natural). 4.To provide information on temporal trends in radionuclide and metal levels in several caribou herds to determine whether levels are increasing, decreasing or remaining the same over time. 5. To determine the efficacy of international controls in reducing or eliminating pollutants entering the Canadian Arctic terrestrial ecosystem. Barren-ground caribou are found across northern Canada, and are a major component of the traditional diet in communities across the Northwest Territories (NWT) and Nunavut. Caribou are a good indicator species for terrestrial ecosystem contamination given their wide distribution across northern Canada, the simple air-lichen-caribou food chain, the existing baseline data set, and their importance as a country food species. Three (3) caribou herds from across the NWT and Nunavut have been selected as sentinel herds, with a different herd to be sampled each year to determine tissue residue levels and monitor temporal trends. Field collections will be conducted in cooperation with local Hunter’s and Trapper’s Organizations and/or local aboriginal organizations, utilizing local hunters in planning and conducting the field work. Samples will be tested for a wide range of environmental contaminants including 10 heavy metals and 7 radionuclides.

62. LTER HAUSGARTEN

Multidisciplinary investigations at the LTER (Long-Term Ecological Research) observatory HAUSGARTEN are carried out at a total of 21 permanent sampling sites in water depths ranging between 250 and 5,500 m. From the outset, repeated sampling in the water column and at the deep seafloor during regular expeditions in summer months was complemented by continuous year-round sampling and sensing using autonomous instruments in anchored devices (i.e., moorings and free-falling systems). The central HAUSGARTEN station at 2,500 m water depth in the eastern Fram Strait serves as an experimental area for unique biological in situ experiments at the seafloor, simulating various scenarios in changing environmental settings. Time-series studies at the HAUSGARTEN observatory, covering almost all compartments of the marine ecosystem, provide insights into processes and dynamics within an arctic marine ecosystem and act as a baseline for further investigations of ongoing changes in the Fram Strait. Long-term observations at HAUSGARTEN will significantly contribute to the global community’s efforts to understand variations in ecosystem structure and functioning on seasonal to decadal time-scales in an overall warming Arctic and will allow for improved future predictions under different climate scenarios.

67. Assessment of spatial and temporal patterns of HCH isomers in the arctic environment

In order to assess the spatial and temporal patterns of the a-, b- and g-isomers of hexachlorocyclohexane (HCH) in the arctic biotic and abiotic environment, it is proposed that: (1) concentrations and ratios of HCH isomers be compared over time in air, water, seals, beluga, polar bears and seabirds to determine any shifts in isomeric ratios and how those shifts interrelate among the various media, and (2) concentrations and ratios of HCH isomers be compared spatially in the abiotic and biotic media and reasons for any patterns explored.

68. Retrospective survey of organochlorines and mercury in arctic seabird eggs

In order to address the the question of utility of arctic seabird eggs as an indicator of contaminant temporal trends, it was proposed that: (1) archived arctic seabird egg contents be re-analyzed for organochlorines according to a standardized pooling and analytical protocol in order to confirm whether those residues have been decreasing since the mid-1970s, (2) archived arctic seabird egg contents be analyzed for mercury and selenium to determine whether or not those levels have been increasing or decreasing since the mid-1970s, (3) egg contents and adult livers be analyzed by full scan and ICP to identify any "new" or previously unidentified organochlorines (MS full scan) or metals (ICP) which may have entered the Canadian arctic food chain.

69. Role of contaminants in seaduck population decline: metals in oldsquaw

In order to determine the role of contaminants in declining populations of seaducks, it is proposed that: (1) archived samples of Oldsquaw collected from their Canadian arctic breeding grounds be analyzed for Hg, Se and Cu (in liver), Cd (in kidney), Pb (in wing bone), and selected samples be screened for a wider range of metals (in liver), and (2) archived samples of Oldsquaw wing bone be analyzed for stable isotopes (13C/12C; 15N/14N, and 34S/32S) and strontium (Sr) to discriminate whether birds from certain geographical areas of the Arctic are overwintering in freshwater (i.e. Great Lakes) or marine environments.

80. Plants obtained from permanent study plots as bioindicators for radioactive fallout

Vascular plants and mosses are also terrestrial bioindicators for radioactive fallout, The summer fodder of reindeer consist of 200- 300 vascular plants . Therefore vascular plants are an important link in the foodchain plants - reindeer/game - man. STUK has several permanent plant sampling sites, usually in the vicinity of the lichen plots. Only a few of of them are included in Finnish NIP. The results obtained are gammanuclide or occasionally also 90Sr concentrations, Bq/kg.
