The aim of the present project is to continue the monitoring of contaminants Greenland biota in order to detect temporal and geographical changes including screening and retrospective analyses of "new" contaminants of increasing concern. Furthermore, temporal trend monitoring of selected biomarkers (e.g. bone mineral density and histopathological changes) in polar bear are included in the monitoring as these have shown to be sensitive to stressors such as contaminants. The project will provide the fundamental basic knowledge of temporal trends and feed into international geographical trend studies of mainly long range transport of contaminants in the atmosphere and biota to Greenland. The project will provide an important input to international convention works such as the Stockholm Convention and the Long-range Trans-boundary Air Pollution.

Det danske bidrag til Arctic Monitoring and Assessment Programme (AMAP) under Arktisk Råd har dokumenteret at østgrønlandske isbjørne er mest forurenede mht. fedtopløselige organiske miljøgifte. Siden 1999 har Danmarks Miljøundersøgelsers Afdeling for Arktisk Miljø (DMU-AM) undersøgt isbjørnesundheden i Østgrønland via et unikt samarbejde med lokale bjørnefangere, og et tværfagligt samarbejde med biologisk, veterinær og human medicinske fagområder i Grønland og Danmark samt internationale samarbejdsrelationer med Canada, Norge og Tyskland. Undersøgelserne er mundet ud i en lang række af række internationale videnskabelige publikationer som dokumenterer tidstrend i miljøbelastningen af de grønlandske og norske isbjørne og sammenhængen mellem forurening og helbredseffekter på isbjørne. Disse har fået omtalt presseomtale verden over.

The IPY-project ‘COPOL’ has a main objective of understanding the dynamic range of man-made contaminants in marine ecosystems of polar regions, in order to better predict how possible future climate change will be reflected in levels and effects at higher trophic levels. This aim will be addressed by 4 integrated work packages covering the scopes of 1) food web contaminant exposure and flux, 2) transfer to higher trophic levels and potential effects, 3) chemical analyses and screening, 4) synthesis and integration. To study the relations between climate and environmental contaminants within a project period of four years, a “location-substitutes-time”-approach will be employed. The sampling is focussed towards specific areas in the Arctic, representing different climatic conditions. Two areas that are influenced differently by different water masses are chosen; the Kongsfjord on the West-coast of Spitzbergen (79N, 12 E) and the Rijpfjord North-East of Svalbard (80N, 22 E). The main effort is concentrated in the Kongsfjord. This fjord has been identified as particularly suitable as a study site of contaminants processes, due to the remoteness of sources, and for influences of climatic changes, due to the documented relation between Atlantic water influx and the climatic index North Atlantic Oscillation (NAO). The water masses of the Rijpfjord have Arctic origin and serves as a strictly Arctic reference. Variable Atlantic water influx will not only influence abiotic contaminant exposure, but also food web structure, food quality and energy pathways, as different water masses carry different phyto- and zooplankton assemblages. This may affect the flux of contaminants through the food web to high trophic level predators such as seabirds and seals, due to altered food quality and energy pathways.

Polar bears are at the top of the arctic marine food chain. Owing to the high lipid content of their diet, polar bears appear particularly prone to bioaccumulate organochlorines. Polar bears from East Greenland and Svalbard have higher contaminant levels than polar bears elsewhere in the Arctic. Levels of PCBs in these areas might negatively affect reproduction and survival. So far more than 130 polar bear samples have been collected since 1999. These samples are being analysed for organochlorines and pathological effects.

The project includes analyses of PCBs, organochlorine pesticides, chlordanes and brominated flame retardants in seals, birds and fish from Greenland. The programme covers a period of five years to investigate temporal trends in the concentration levels of organic pollutants in Greenland.

The project studies the development through time of contaminants (heavy metals and organic pollutants) in animals in Greenland.

Examine temporal and spatial variation in trace metal concentrations in the western Arctic through the analysis of Black Guillemot feathers. Temporal trends being examined using study skins collected as early as 1897. Spatial variation examined in conjunction with carbon isotope signatures in feathers and by sampling both winter and summer plumages. Regional climate change monitored through examination of annual variation in breeding chronology and success in relation to snow and ice melt.

Brief: Assessment of the significance of aquatic food chains as a pathways of exposure of indigenous peoples to PTS, assessment of the relative importance of local and distant sources, and the role of atmospheric and riverine transport of PTS in Northern Russia. Project rationale and objectives: (1) To assess levels of Persistent Toxic Substances (PTS) in the environment in selected areas of the Russian North, their biomagnification in aquatic and terrestrial food chains, and contamination of traditional (country) foods that are important components of the diet of indigenous peoples. (2) To assess exposure of indigenous peoples in the Russian North to PTS, and the human health impacts of pollution from local and remote sources, as a basis for actions to reduce the risks associated with these exposures. (3) To inform indigenous peoples about contamination by PTS of their environment and traditional food sources, and empower them to take appropriate remedial actions to reduce health risks. (4) To enhance the position of the Russian Federation in international negotiations to reduce the use of PTS, and to empower the Russian Association of Indigenous Peoples of the North (RAIPON) to participate actively and fully in these negotiations. Project activities to achieve outcomes: (1) Inventory of local pollution sources in the vicinities of selected indigenous communities. (2) Survey of levels and fluxes of PTS in riverine and coastal marine environment important for indigenous peoples living in these environments and using them for their subsistence; and assessment of fluxes of PTS to these environments via selected rivers and the atmosphere. (3) Dietary surveys of selected indigenous communities. (4) Study of biomagnification, based on measurements of selected PTS in representative species in food chains important for the traditional diet of indigenous populations. (5) Survey and comparative assessment of pollution levels of the indigenous and general population in selected areas. (6) Dissemination of results to all relevant stakeholders.

White whale (Delphinapterus leucas) blubber samples from three of the five different Alaskan stocks - Cook Inlet (n = 20), Eastern Chukchi Sea (n = 19) and Eastern Beaufort Sea (n = 2) - were analyzed for levels and patterns of chemical contaminants. Blubber of these whales contained sum PCBs, sum DDTs, sum chlordanes, HCB, dieldrin, mirex, *toxaphene and *HCH, generally in concentration ranges similar to those found in white whales from the Canadian Arctic and lower than those in white whales from the highly contaminated St. Lawrence River. The males of the Cook Inlet and Eastern Chukchi Sea stocks had higher mean concentrations of all contaminant groups than did the females of the same stock, a result attributable to the transfer of these organochlorine contaminants (OCs) from the mother to the calf during pregnancy and during lactation following birth. Principal components analysis of patterns of contaminants present in blubber showed that Cook Inlet stock appeared to have identifiable contaminant patterns that allowed the stock to be distinguished from the others. Our results also showed that blubber from the three Alaskan stocks was a source of contaminant exposure for human subsistence consumers, but the health risks from consumption are currently unknown.

Blubber samples from Alaska ringed seal (Phoca hispida) were collected for inclusion in the US National Biomonitoring Specimen Bank, as well as for immediate analysis as part of the contaminant monitoring component of the US National Marine Fisheries Service's Marine Mammal Health and Stranding Response Program. The blubber samples were analyzed for organochlorine (OC) contaminants (e.g., PCB congeners, pesticides, DDTs). Results for ringed seals from the Alaska Arctic revealed low blubber concentrations of OC contaminants. Differences in contaminant concentrations among the Alaska seals may be explained by differences in feeding habits and migratory patterns; age or gender did not appear to account for the differences observed. The integration of real-time contaminant monitoring with specimen banking provides important baseline data that can be used to plan and manage banking activities. This includes identifying appropriate specimens that are useful in assessing temporal trends and increasing the utility of the banked samples in assessing chemical contaminant accumulation and relationships to biological effects.
