  1. 6. Waterborne pollution from mining in cold climates : Potential catchment-scale immobilization of substances by microbial sulfate reduction (MSR)

    Författare :Sandra Fischer; Jerker Jarsjö; Gunhild Rosqvist; Carl-Magnus Mörth; Anna-Kaisa Ronkanen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; abandoned mines; metal pollution; sulfur isotopes; bacterial sulfate reduction BSR ; nature-based solution NBS ; naturgeografi; Physical Geography;

    Sammanfattning : Waterborne pollution from mining is impacting groundwater and surface water resources in many regions of the world. Main problems include acidification and high levels of dissolved toxic metals that adversely affect humans and ecosystems. LÄS MER

  3. 7. Air pollution and dementia in a low exposure setting : the role of noise, olfaction, and theapoe gene

    Författare :John Andersson; Maria Nordin; Anna Oudin; Anna Sundström; Tom Russ; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Air pollution; Road traffic; NOx; dementia; APOE; Alzheimer’s disease; Apolipoprotein E; olfaction; particulate matter; vascular dementia; odor identification; odor detection; Psychology; psykologi;

    Sammanfattning : Previous research indicates an association between air pollution exposure, and risk of dementia. Still, a number of factors that may play a role in this association remain to be explored. LÄS MER

  4. 8. Prescription – Pollution – Poo – Pandemics - Priorities : Neuraminidase Inhibitors from an Environmental Resistance Development Perspective

    Författare :Marie Nykvist; Josef D. Järhult; Mikael Leijon; Uppsala universitet; []
    Nyckelord :Influenza A virus; neuraminidase inhibitor; resistance; environmental; Mallard; zanamivir; avian influenza;

    Sammanfattning : The natural Influenza A virus (IAV) host is waterfowl. Human IAV is treated with neuraminidase inhibitors (NAIs), which are stockpiled worldwide in case of an IAV pandemic. As the drugs escape regular waste water treatment, they can be detected in river waters. LÄS MER

  5. 9. Performance of Non-ceramic Insulators in Tropical Environments

    Författare :M. A. R. Manjula Fernando; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution; high voltage insulator; leakage current; testing;

    Sammanfattning : Non-ceramic insulators have been tested in the field and under laboratory conditions in many countries for more than three decades. Nevertheless, information about their performance in tropical environments is rather limited. Thus, this project was conducted in order to fill the gap. LÄS MER

  7. 10. Nutrient imbalance in Norway spruce

    Författare :Gunnar Thelin; Avdelningen för kemiteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silviculture; Växtekologi; Plant ecology; nitrogen saturation; base saturation; pH; multiple limitation; deficiency; copper; boron; potassium; pollution; sustainability; conifers; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära;

    Sammanfattning : The studies presented in my thesis indicate that growing Norway spruce in monoculture does not constitute sustainable forest management in a high N and S deposition environment, such as in southern Sweden. The combination of N-induced high growth rates and leaching due to soil acidification causes soil reserves of nutrients to decrease. LÄS MER
