  1. 1. Temporal and spatial trends of organohalogens in guillemot (Uria aalge) from North Western Europe

    Författare :Hrönn Jörundsdóttir; Åke Bergman; Derek Muir; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; environmental; monitoring; pollution; time trends; spatial trends; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Sammanfattning : The Arctic and sub-Arctic region of the North Atlantic is a remote area, also in relations to environmental contaminants, such as POPs, BFRs and last but not least, PFCs. Both the BFRs and PFCs are considered emerging pollutants of significant environmental concern. LÄS MER

  3. 2. International migration and coronary heart disease

    Författare :Ebba Hedlund; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; migration; coronary heart disease; country of birth; twins; Public health science; Folkhälsovetenskap; Environmental medicine; Miljömedicin;

    Sammanfattning : In today’s globalised world, with considerable international migration, knowledge about the health of immigrants is becoming increasingly important. In Sweden, about 13% of the population or over one million persons are born outside the country. LÄS MER

  4. 3. Generation, stability and migration of montmorillonite colloids in aqueous systems

    Författare :Sandra García García; Mats Jonsson; Tiziana Missana; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; colloid stability; colloid migration; geological disposal; nuclear waste; granitic fractures; ; Environmental chemistry; Miljökemi; Environmental toxicology; Miljötoxikologi; Surface and colloid chemistry; Yt- och kolloidkemi; Nuclear chemistry; Kärnkemi;

    Sammanfattning : In Sweden the encapsulated nuclear waste will be surrounded by compacted bentonite in the granitic host rock. In contact with water-bearing fractures the bentonite barrier may release montmorillonite colloids that may be further transported in groundwater. LÄS MER

  5. 4. Pastoralists and the Environmental State : A study of ecological resettlement in Inner Mongolia, China

    Författare :Qian Zhang; Bo Malmberg; Andrew Byerley; Richard Black; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Environmentalisation; political ecology; grassland degradation; migration decision-making; pastoralism; environmental migration; environmental governance; China; Geography with Emphasis on Human Geography; geografi med kulturgeografisk inriktning;

    Sammanfattning : China's quest for sustainable development has given birth to a set of contested ‘ecological construction’ programmes. Focusing on ‘ecological resettlement’, a type of policy measure in a programme for restoring degraded grasslands, this thesis sets out a critical analysis in opposition to the dominant technical and managerial approaches to understanding environmentalisation.

  7. 5. Ecology and evolution of large-scale bird migration patterns : A natural history and comparative study of the migration in common and little ringed plovers

    Författare :Linus Hedh; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ringed plover; leap-frog migration; migration speed; migration process; light level geolocator; migration;

    Sammanfattning : Migration distance and seasonal redistribution patterns may vary between and within bird populations. A common pattern is leap-frog migration, in which northerly breeding populations migrate farther and winter south of more southerly breeding populations. LÄS MER
