4. Monitoring of contaminants in atmosphere and biota in Greenland

The aim of the present project is to continue the monitoring of contaminants in air and biota in Greenland in order to detect temporal and geographical changes. Furthermore, temporal trend monitoring of selected biomarkers (e.g. bone mineral density and histopathological changes) in the polar bear populations will be initiated 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.

10. ARCTIC - Advanced Research on Contaminant Transfer, Impact and Consequences

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.

11. AMAP 2009 and 2010 core HM and POP programme Faroe Islands

The project is a continuation of the monitoring activities of the AMAP POPs and Heavy metals programme in marine, terrestrial and freshwater environments of the Faroe Islands. The aims of the programme is to establish data for timetrend and spatial assessments as well as providing data of importance in human health risk assessment on mercury and POPs. The programme incorporates analyses on pilot whale, cod, black guillemots from the marine environment, sheep and hare from the terrestrial environment and arctic char from the freshwater environment. The compounds analysed are "legacy" POPs and mercury, cadmium and selenium. In addition, a retrospective analyses of PFOS in pilot whale tissues going back as far as possible (ie.1986) is part of the project.

12. A survey of contaminants in peregrine falcon eggs from South Greenland

The primary scope of the project is to investigate the long-term time trend of brominated flame retardants for the contamination and possible effects in relation to the contamination of peregrine falcon eggs. The contamination by the conventional POP compounds will also be identified. Totally 36 out of 53 collected eggs will be analysed. Time trend analysis will be performed based on a multi-variant methodology for a period of 18 years. The result will contribute to the assessment of organic pollutant contaminationm in Greenland including the effect on vulnerable wild life.

13. Contaminants in polar bears

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.

14. AMAP Time Trend Programme

15. Controlled dose-control experiment on POP in sledge dogs

Organochlorines (OCs) concentrate through the arctic marine food webs and are stored in the adipose tissue due to their high lipophilic and persistent characteristics. The polar bears receive high doses of POPS through their diet and a controlled experimt was need to resolve effect on the immune system and effects on internal organs. Such a controlled experiment on sledge dogs as a replacement test organism for the polar bear was conducted from 2004-2006 to investigate dose-response effects.

16. Contaminants in polar fox

Arctic animals utilize periods with high food availability for feeding and lipid deposition, whereas they rely on stored lipids during unfavorable periods. Hence, many arctic inhabitants exhibit profound seasonal cycles of fattening and emaciation. In the Arctic, feeding is associated with fat deposition and contaminant accumulation. When lipids are mobilized, accumulated contaminants are released into the circulation. Consequently, blood contaminant concentrations may increase markedly and result in a redistribution of the contaminant(s) from “insensitive”, adipose tissues to sensitive organs, and increased contaminant bioavailability. Such variations complicate interpretations of pollutant toxicity, both in effect studies and in monitoring programs, and remains an important future reseach area. In the present study, we will use arctic fox (Alopex lagopus) as a model species for investigating tissue distribution and bioavailability of organochlorine contaminants (OCs) in relation to natural variations in lipid status (field study). These data will be supplemented and validated through a contamination study with blue fox (A. lagopus), where the seasonal changes in lipid status of wild fox are simulated in the laboratory. In both the field and laboratory study, possible effects of OCs on steroid hormone synthesis, and plasma levels of hormones, vitamin E and retinol will also be assessed.

17. Reducing the environmental impact of sea cage fish farming through the cultivation of seaweeds

Although the most visible effect of fish cage aquaculture is the output of particulate organic waste, 80% of the total nutrient losses from fish farming are plant-available as potentially eutrophicating substances. This project will assess the ability of commercially important seaweeds, cultivated in the immediate vicinity of caged fish, to reduce the impact of such nutrient releases. The algae cultivated in high nutrient sites will be tested as a food source for humans and for cultivated shellfish, and a model of the distribution of dissolved contaminants from sea-cage fish farms will be developed to predict the impact of introducing algal cultivation at any site.

20. Environmental contaminants in Peregrine Falcons in Alaska, USA

Contaminants were examined for trends over time, spatial variation based on disparate breeding areas, and relationships with measures of productivity. Most organochlorines and metals declined over time. Mercury was the only contaminant with possibly increasing concentrations in eggs. Egg and feather samples collected in 2000 will provide more information on mercury trends and effects. This study embodies 20 years of data on environmental contaminants in peregrine falcons nesting in Alaska.
