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.
National Monitoring Programme in Sweden. The purpose is to quantify deposition (mainly of sulphur and nitrogen), and to illustrate effects in the soil, for example possible acidification. The aim of the network is to describe the current situation, regional differences, trends over time, and the effects of acid deposition. The atmospheric deposition of sulphur and nitrogen are the main causes of current acidification of ecosystems. Acidification results in substantial pH reduction in soil, groundwater, lakes and water courses. Deposition is investigated as precipitation studies in open field areas (bulk precipitation) and by throughfall studies in nearby forest stands. For sulphur and chloride, throughfall monitoring is useful for determination of total deposition. In areas, or during periods with low sulphur deposition, internal circulation in vegetation might influence results from throughfall measurements significantly. For nitrogen and base cations (mainly potassium and manganese) canopy interaction is important. Air concentrations of sulphur and nitrogen dioxide, ammonia, and ozone are measured at some locations. The observations made are: (i) air chemistry (SO2, NO2, NH3, O3); (ii) soil water chemistry (pH, Alk, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn, Fe, ooAl, oAl, Al-tot, total organic carbon); (iii) deposition in open field (precipitation, H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn); (iv) deposition in forest (throughfall, H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn). For nitrogen and base cations (mainly potassium and manganese) canopy interaction is important. Soil solution chemistry in the forest stands is used as indicator of soil conditions.
The aim of this project is to measure the airborne deposition of acidifying and eutrophicating compounds (gaseous and particulate reduced and oxidised nitrogen and sulphur compounds) in air and precipitation over Sweden at high altitude. The results from this programme is used to calculate and model basic processes governing sources, atmospheric transport and sinks of atmospheric trace constituents. The observations are made at three stations. The measurements include particulate reduced and oxidised nitrogen and sulphur compounds in gaseous and particulate form in air and precipitation.
This project is now part of the project : Acidifying and Eutrophifying Substances in Air and Precipitation
National Environmental Monitoring in Sweden. The project is included in a European Monitoring and Evaluation Programme network (EMEP). The subprogram main task is to check if international agreements as UN Convention on Long range Trans-boundary Air Pollution (CLTRAP) is followed. The measurements follow up the Swedish national generational goals "Natural Acidification Only", "A Non-Toxic Environment" and "Clean Air". The network comprises 10 stations, out of which three are in north Sweden, the two one are in AMAP area. Air chemistry is monitored by diffusion samplers. The following compounds are measured: SO2, SO4, tot-NH4, tot-NO3, soot, NO2. Precipitation quality is monitored following measured compounds: SO4-S, NO-N, Cl, NH4-N, Ca, Mg, Na, K, pH, EC. Metals in air and precipitation are analysed only at one north station (Bredkälen), and include: As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn, V, Hg, methyl-Hg.
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.
National Environmental Monitoring in Sweden. Monitoring of heavy metals in fish is performed in 110 trend lakes in Sweden. Annual sampling is carried out in 32 lakes, of which seven are in AMAP area. Three fish species have been selected: Arctic char (Salvelinus alpinus), Northern pike (Esox lucius), and Perch (Perca fluviatilis). A selection of metals is analysed in prepared samples of muscle and liver tissue. Analysed metals in liver are : Al, Ag, As, Bi, Cd, Cr, Cu, Ni, Pb, Sn and Zn. In muscle samples Hg and stabile isotopes δ 15N, δ 13C are analysed.
This project has been divided into two new projects: The Swedish Forest Soil Inventory and the Swedish National Forest Inventory.
The Swedish National Forest Inventory has the task of describing the state and changes in Sweden's forests. The inventory gathers basic information on forests, soils and vegetation. It includes most aspects concerning soils, for example: soil types, soil chemistry including organic matter, water conditions and content of stones and boulders. Acidification, nitrogen deposition and the contribution by soils to climate change are some of the current issues dealt with. Regularly reported variables are: forest state, injuries, and growth, logging operations, new forest stand, and environmental assessment. Invented variables on permanent sampling plots include: position in the landscape, field vegetation, site conditions, soil sampling, assesment of soil characteristics, chemical analysis of soil in O-, B-, BC- and C-horizons.
National Environmental Monitoring Programme in Sweden. The objective is to follow the deposition of heavy metals over Sweden by the analyses of their concentration in two selected species of moss. The selected species are: Red-stemmed Feather-moss (Pleurozium schreberi) and Mountain Fern Moss (Hylocomnium splendens). Preferred specie: Red-stemmed Feather-moss (Pleurozium schreberi). Metals adsorbed by mosses almost exclusively come from the air and metal concentration in mosses are therefore seen as a proxy for metal deposition. Analysed elements are: Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, V, Zn (2015). The moss samples are taken from over 600 stands across Sweden.
Annual measurements of physical, chemical, and biological variables are taken in small to medium sized, mostly minimally disturbed lakes, situated across the country. Of the 108 lakes that are part of the Trend Station Lake monitoring programme, 20 are situated in AMAP area. The main aim of the monitoring programme is to document long-term changes related to global or regional change and human-generated stressors. To complement the Trend Station Lake monitoring programme, national lake surveys provide spatial data needed to determine regional patterns, and coupled with time-series data, changes in surface water quality. The National Lake Survey (the Surveillance Stations, re-sampled stations) programme for lake water quality, started in 2007 and results in data of all Swedish lake conditions. Each year some 800 new lakes are sampled to determine chemical and physical conditions; lakes are resampled at 6 year intevals. 4824 lakes are sampled in the country during a six-year sampling cycle, with 1270 situated in AMAP area. The variables included in the Trend Station Lake monitoring programme include water chemistry, fish, phytoplankton, macrophytes, zooplankton, and benthic invertebrates, whilst the National Lake Survey is focused solely on chemical and physical parameters.
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).
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.
The possibility of restoring the salmon stocks in the Tuloma system is assessed by collecting background information on the river system: present fish fauna, habitat quality, migratory routes etc. Planning the restoration including technical and management aspects is under way.
Monitoring of the salmon stocksof the Teno and Näätämö river systems is based on long term data collection on juvenile salmon production, biological characteristics of the spawning stock, origin of salmon (wild/reared) and statistics on fishery and catches. Information on other fish species than salmon is also available.
The general objective of the human health sub-programme is to protect and promote the health of Arctic peoples, especially children, with respect to exposure environmental contaminants.
The main specific objectives of UFTIR are: (1) To revise and homogenise the analyses of available experimental data for providing consistent time series of distinct tropospheric and stratospheric abundances of the target gases using new inversion algorithms. A common strategy for retrieval and characterisation of the vertical distributions of the target gases from FTIR ground-based measurements will be established. (2) To provide quantitative trends and associated uncertainties for the target gases over about the last decade, as a function of latitude throughout Western Europe, focusing on the troposphere. (3) To integrate the data in model assessments of the evolutions of tropospheric abundances. The measured burden and changes of the tropospheric gases will be compared with 3D model simulations, in order to help developing the latter, assist in explaining potential causes for the observed changes and to assess the consistencies between the trends at the surface to the free troposphere and lowermost stratosphere, and the agreement with known evolutions of emissions. UFTIR will make the community prepared to deliver tropospheric data for validation and synergistic exploitation of new satellite experiments like ENVISAT.
