Arctic, Circumpolar: projects/activities

To edit or add records to any of the catalogs, log in or create an account.

Directory entires that have specified Arctic, Circumpolar as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

1. Organic substances in biota

National Environmental Monitoring in Sweden. The monitoring of persistent organic pollutants (POPs) in fish is performed in 110 lakes in Sweden and annual sampling is carried out in 32 lakes, of which 7 are located in or close to the AMAP area. Three fish species have been selected: Arctic char (Salvelinus alpinus), Northern pike (Esox lucius), and Perch (Perca fluviatilis). Fish are sampled, prepared, and stored in the Environmental Specimen Bank (ESB) at the Swedish Museum of Natural History (NRM). PCB, HCH, HCB, DDT, DDE, PFAS and PBDE are some of the POPs that are analysed.

2. Persistent organic pollutants in air and precipitation

National Environmental Monitoring Programme in Sweden. Measurements of persistant organic pollutants in air and precipitation are carried out at Råö, Hallahus, Aspvreten, and in Pallas (Northern Finland). The monitoring programme includes measurements of: polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), some pesticides (HCH, DDT) and polybrominated diphenylethers (PBDE).

3. Metals in reindeer

National Environmental Monitoring Programme in Sweden. The objective of the project is to follow time trends of available metals in vegetation and reindeer (Rangifer tarandus) in Lapland, Sweden. Analysed metals in liver and muscle samples are: Al, Cd, Co, Cr, Cu, Mg, Mn, Ni,Hg, Pb, Zn. Analyses were performed on a continuous basis until 2005. Since then there has only been a collection of samples to be stored in the Environmental Specimen Bank (ESB) at the Swedish Museum of Natural History (NRM).

4. 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.

5. LAPBIAT-Lapland Atmosphere-Biosphere facility

The main objective of the facility is to enhance the international scientific co-operation at the seven Finnish research stations and to offer a very attractive and unique place for multidisciplinary environmental and atmospheric research in the most arctic region of the European Union. Factors such as, arctic-subarctic and alpine-subalpine environment, northern populations, arctic winters with snow, changes in the Earth's electromagnetic environment due to external disturbances and exceptionally long series of observations of many ecological and atmospheric variables should interest new users.

6. Determination of atmospheric fluxes of Radionuclides, Heavy Metals and Persistent Organic pollutants in well defined watershed, lakes and coastal marine sediments of Svalbard from the beginning of nuclear age

The 2003 field activity will be mainly dedicated to coring activity which includes: 1. the sampling of snow and ice cores from a Ny-Ålesund nearby glacier (midre Lovenbreen). 2. the collection of near coast (Kongsfjorden) and lakes sediments (maximum under pack depth 30 m). Sampling collection of ice and sediment cores will be performed using a portable, electric operated, sampling corer. The transport of all materials up to each sampling station should be performed with snowcats.

7. The P450 enzyme system of the Arctic charr as a biomarker of POP contamination in Arctic aquatic environments

Validate the hepatic P450 enzyme system as a biomarker of levels and effects of POPs in Arctic, aquatic environments, using the anadromous (sea-migratory) Arctic charr as an indicator species.

8. Xenobiotic impact on Arctic charr: Nutritional modulation and physiological consequences

The objectives are to test the hypothesis that the tissue re-distribution of PCB are linked to the metabolic status of the Arctic charr and that the tissue re-distribution of PCB associated with fasting will decrease the overall performance characeristics of the Arctic charr.

9. Effects and Trends of POPs on Polar Bears

LONG TERM: Determine the effects, at the individual and population level, of persistent organic pollutants (POPs) and their metabolites in the polar bear; determine trend of POPs in the Arctic marine environment using polar bear tissues as a biomonitor. SHORT TERM: a. Determine 10-year temporal trends of POPs in the Hudson Bay Sub-Arctic Ecosystem from 1990-1989 by analysis of archived polar bear biopsy samples, including changes in enantiomeric composition of -HCH and chlordane compounds and ratio of -HCH/-HCH (cross-referenced to separate proposal on HCHs). b. Determine if there is selective tissue distribution of the enantiomers of chiral contaminants in polar bears, which may influence target organ toxicity, by analysis of archived polar bear samples. c. Determine the endocrine disrupting effect of POPs on testosterone and PCB metabolite profiles by in vitro metabolism studies using polar bear liver microsomes. d. In collaboration with CWS P&N Region, the Norwegian Polar Institute and the Norwegian Veterinary Institute, determine the immunotoxic effects of PCBs and other organochlorines in polar bears throughout a gradient of exposure (Hudson Bay, low; Svalbard, high). e. Determine the effects of hydroxy-PCBs on circulating thyroid hormone and vitamin A concentrations.

10. AMAP Human Health Data Centre

The objectives of the centre are: - to provide access to data from recent human health monitoring and research activities conducted as part of the AMAP national implementation plans. - to provide a means to ensure treatment of data in a consistent manner, uniform statistical analysis etc., including application of objective quality assurance procedures. - to begin the process of establishing a long-term archive of relevant Arctic monitoring data for use in future assessments of temporal trends etc. - to meet the ministerial request from the Alta Conference to include human health data in the AMAP thematic data centres.
