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.
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.
National Environmental Monitoring in Sweden in "Air" programme and sub-programme "the thickness of the ozon layer". The project follows changes in the thickness of the ozone layer in the atmosphere over Sweden.
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.
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.
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.
As part of the Austrian radioactivity monitoring network an air sampler and a high resolution radioactivity detection system is installed at the high altitude Sonnblick Observatory (3105 m). The objective is to monitor the radioactivity in air at high altitudes.
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.
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.
1) To determine tissue residue levels of organochlorines and metals in arctic fox feeding in or near an arctic coastal environment. 2) To assess whether or not residue levels found in arctic fox pose a potential wildlife health risk. 3) As part of a pilot project, to determine residue levels and assess potential wildlife health risk to wolverines feeding in or near a coastal environment.
Elevated levels of 137Cs caused by previous atmospheric nuclear weapons tests fallout and the Chernobyl accident have been observed in Finnmark, Northern Norway. Due to the large consumption of potentially contaminated reindeer meat, whole body measurements of 137Cs levels in reindeer herders have been performed since 1965.
The objective is to develope a tool that can be used as individual dietary advice. The tool can be used by health services, but also by individual internet users. The exposure can be calculate based on the food item intake, and the exposure will be compared with tolerable-acceptable intake limits
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 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.
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 (79N, 12 E) and the Rijpfjord North-East of Svalbard (80N, 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.
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.
The effects of biofilm settlement on corrosion resistance of stainless steels in polar seawaters are not well known. In warmer conditions (Mediterranean sea) biofilm increases both the risk of localised corrosion onset and the propagation rate of corrosion attack. Corrosion tests carried out in Antarctica demonstrated that biofilm growth at about 0°C induced electrochemical effects less important than those occurring in warmer conditions. On the contrary, corrosion tests performed in similar environmental conditions at Ny-Aalesund (Svalbard) showed more severe corrosion attack than in Antarctica. This research aims: - to define the influence of biofilm on stainless steel corrosion resistance in polar seawater in the range of temperature between -1 and +5 °C, - to define if change in salinity can influence corrosion process, - to identify stainless steel grades which can be acceptable in such conditions (polar seawater seems to be somewhat less corrosive, which gives the possibility to use cheaper stainless steels).
Marine foodwebs as vector and possibly source of viruses and bacteria patogenic to humans shall be investigated in a compartive north-south study. Effects of sewage from ships traffic and urban settlements, on animals of arctic foodwebs will be studied.
During the last decade the concern regarding environmental effects of the offshore industry has shifted from effects of drilling discharges on benthic communities, towards a stronger focus on the water column and effects on the pelagic ecosystem. At the same time, oil and gas development is expanding in the Norwegian and Russian sectors of the Barents Sea. In this regard, a project has been initiated to look at responses of especially Calanus spp. and other copepod species to long-term, sublethal exposure to selected offshore discharges and discharge components, as well as accidental oil spills. Calanus spp. is ecologically the most important zooplankton species along the Norwegian shelf and in the Barents Sea. A laboratory based facility for culture through several generations is being developed through this project. In addition, the impact of oil compounds on the cold-water and arctic Calanus species-complex will be examined by carrying out a series of laboratory (some at Ny Ålesund) and ship based experiments. The response parameters will include both behavioral (feeding, mate finding, avoidance) and physiological (mortality, egg production, development rates, oxygen consumption and assimilation efficiency) parameters. The ultimate outcome of this research is expected to be a supporting instrument for ecological risk assessment of offshore discharges, which is highly relevant both to the North Sea, the mid-Norway shelf and the Barents Sea.
