    Author : Ylva Persson; Mats Tysklind; Lars Öberg; Staffan Lundstedt; Jaana Koistinen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; contaminated soil; hydrophobic organic contaminant; chlorinated phenoxyphenol; chlorinated diphenyl ether; chlorinated dibenzofuran; chlorinated dibenzo-p-dioxin; preservation; mobility; colloid; dissolved organic matter; particulate organic matter; groundwater; equilibrium column test; chlorophenol; Environmental chemistry; Miljökemi;

    Abstract : Mixtures of chlorinated organic pollutants can be found in the soils at chlorophenol-contaminated sawmill, including (inter alia) polychlorinated phenols (CPs), phenoxyphenols (PCPPs), diphenyl ethers (PCDEs), dibenzofurans (PCDFs) and dioxins (PCDDs). These hydrophobic compounds have low water solubility and hence low mobility as truly dissolved compounds. READ MORE

  4. 2. Fractionation of Fe and Zn isotopes : methods and some applications in aqueous geochemistry

    Author : Dmitry Malinovskiy; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : Multiple collector inductively coupled plasma mass spectrometry (MC-ICPMS) has been used for the measurement of Fe and Zn isotope ratios in a variety of sample types including natural and synthetic waters, ferromanganese concretions, sediments and biological material. The focus of this PhD study was the development of analytical procedures for precise and accurate measurement of Fe and Zn isotope ratios by high resolution MC-ICPMS. READ MORE

  5. 3. Seated postural reactions to mechanical shocks : laboratory studies with relevance for risk assessment and prevention of musculoskeletal disorders among drivers

    Author : Tobias Stenlund; Börje Rehn; Ronnie Lundström; Ola Lindroos; Fredrik Öhberg; Rolf Moe-Nilssen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postural balance; Posture; Electromyography; Musculoskeletal pain; Whole-body vibration; Reliability; Kinematics; Biomechanics; sjukgymnastik; Physiotherapy;

    Abstract : Professional drivers of off-road vehicles, driving on irregular terrain such as in forestry, agriculture and mining, are exposed to whole-body vibration and mechanical shocks. These driver groups have reported severe musculoskeletal problems in the spine, but the association to seated postural reactions is not fully understood. READ MORE
