  1. 1. Towards Abatement of Selected Emissions from Metals Manufacturing

    Författare :Diana Orrling; Seshadri Seetharaman; S. Subramanian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mercury; zinc; iron; copper; sulfur dioxide; adsorption; pollution; spectroscopy; thermal desorption; polycrystalline; surfaces; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. LÄS MER

  3. 2. Quantitative methods for evaluation of tremor and neuromotor function: Application in workers exposed to neurotoxic metals and patients with essential tremor

    Författare :Gunilla Wastensson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tremor; neuromotor function; neurobehavioral methods; mercury vapor; manganese; previous exposure; welding; essential tremor; deep brain stimulation;

    Sammanfattning : The overall purpose of this thesis was to investigate the usefulness of certain quantitative methods for detecting or quantifying changes in tremor or other neuromotor functions. Tremor and impairment in neuromotor function may be the early signs of adverse effects due to low-level exposure to neurotoxic metals such as mercury and manganese, and are also common features of neurological diseases.

  4. 3. Pharmacokinetics of mercury from dental amalgam

    Författare :Gunilla Sandborgh Englund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Human; dental amalgam; mercury; blood; plasma; urine; saliva; feces; pharmacokinetics; kidney; chelating agents.;

    Sammanfattning : The overall aim of the present work has been to obtain quantitative and qualitative data on mercury from dental amalgam in humans. The influence of amalgam removal on mercury levels in blood, plasma and urine has been studied in twelve volunteers. All amalgam fillings were removed during one dental session. LÄS MER

  7. 5. Laser spectroscopic analysis of atmospheric gases in scattering media

    Författare :Mikael Sjöholm; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fjärranalys; Remote sensing; Laser spectroscop; Scattering of light; Diode lasers; acoustics; optics; Electromagnetism; optik; akustik; Elektromagnetism; Optical absorption; Nondestructive testing: optical; Interdisciplinary applications of physics; Laser technology; Atom- och molekylärfysik; Atomic and molecular physics; LIDAR remote sensing; Laserteknik;

    Sammanfattning : Laser spectroscopic techniques for gas analysis under various influences of light scattering are explored in a wide spectral range from the ultraviolet to the infrared. The techniques rely on spectrally narrow-band light sources that are used in differential optical absorption measurements. LÄS MER
