  1. 1. Assessment of human exposure to per- and polyfluorinated compounds (PFCs) : exposure through food, drinking water, house dust and indoor air

    Detta är en avhandling från Örebro : Örebro universitet

    Författare :Ingrid Ericson Jogsten; Örebro universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human exposure; per- and polyfluorinated compunds PFCs ; dietary intake; drinking water; indoor environment; TECHNOLOGY; TEKNIKVETENSKAP; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Miljökemi; Environmental Chemistry; Kemi; Chemistry;

    Sammanfattning : Per- and polyfluorinated compounds (PFCs) are detected in humans worldwide but all sources of human exposure have not been fully characterized. The aim of this thesis was to evaluate the contributions from food, water, air and dust as sources for human PFC exposure in the general population. LÄS MER

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

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; colloid stability; colloid migration; geological disposal; nuclear waste; granitic fractures; ; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; NATURAL SCIENCES Chemistry Environmental chemistry Environmental toxicology; NATURVETENSKAP Kemi Miljökemi Miljötoxikologi; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Surface and colloid chemistry; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Yt- och kolloidkemi; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Nuclear chemistry; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik 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

  3. 3. Studies of Volcanic Plumes with Remote Spectroscopic Sensing Techniques -DOAS and FTIR measurements on volcanoes of the Network for Observation of Volcanic and Atmospheric Change-

    Detta är en avhandling från Örebro : Örebro universitet

    Författare :Santiago Arellano; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; FTIR; Remote Sensing; DOAS; NOVAC; Volcanic gas emissions;

    Sammanfattning : Volcanism is a rich geodynamical process, closely linked to the origin and ongoing evolution of the lithosphere, atmosphere, hydrosphere and biosphere. Humans have benefited from the resources provided by volcanoes but also been threatened by the dangers of volcanic eruptions, which accurate prediction remains elusive. LÄS MER
