1. Monitoring of Cs-137 and Sr-90 in consumption milk

Monitoring of cesium-137 and strontium-90 in consumption milk is a sub-programme of a national monitoring program regarding environmental radiation in Sweden. The sub-programme has been ongoing since 1955. In the event of increased deposition of radionuclides, e.g. after a nuclear accident, transfer to cow milk is a quick process. The concentration in milk is therefore a good indicator of any changes of the levels of radionuclides in the area. Monitoring is performed at 5 dairies: Umeå, Sundsvall, Kallhäll, Jönköping and Malmö, where milk is sampled 4 times per year.

2. Measurements of gamma-radiation in the environment

Measurements of gamma-radiation in the environment (from ground to cosmos). Radioactivity in Intensive Net is measured on the soil surface at 28 sites in Sweden. The measurements are continuous and sound the alarm if radioactivity increases. Measured is the dose rate of gamma radiation. Radioactivity in Extensive Net is concerned all municipalities in Sweden which has got one instrument for gamma radiation measurement and each county board has got two. Every seventh month they measure radioactivity at two to four predefined spots as reference measurement. Radioactivity in Air is conducted at five stations with air filter sampling and analysis of radioactivity maintained by Swedish Defence Research Agency (FOI). Out of these stations Umeå and Kiruna are located in northern Sweden.

This project is now part of the project: Acidifying and Eutrophifying Substances in Air and Precipitation

National Environmental Monitoring Programme. National Environmental Monitoring Programme. The PMK Network is part of the national network for deposition measurements. The aim is (i) a long-term monitoring of concentration and deposition of selected air transported compounds caused acidification and eutrophication in different parts of Sweden; (ii) to generate knowledge about long-term variation in the field deposition, (iii) to give the background data from low polluted areas for calculation of pollutants deposition in more polluted areas the monitoring of pollutants in air and precipitations are proceed. Ozon and air samples for analysis of sulphur and nitrogen compounds, HCl as well as basic metal ions (Na, K, Ca, Mg, are taken on a monthly basis in air and precipitation. Ozone, as well as sulphur and the nitrogen compound particles are measured in air, and sulphur and nitrogen compounds, base cations, pH and electro-conductivity in precipitation.

5. 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.

6. 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.

7. Determination of cloud coverage and radiative forcing from surface measurements

Specific objectives of the proposal are: 1. the determination of the cloud coverage by means of a simple methodology based on radiometric measurements; 2. the determination of the radiative forcing produced by different type of cloud and coverage for applications into GCM’s as ‘cloud parameterisations’. The results will be obtained for two different radiative regimes by means of different experimental campaigns.

8. 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.

9. 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.

10. 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.
