  2. 1. Trace Element Analysis with Application to Environmental Pollutants Studies in Vietnam

    Author : Thi Hong Nguyen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blood; environmental samples; discriminant analysis; ICP-MS; coal mining; hair; EDXRF; microwave digestion; CV-AAS; urine; sample preparation; coal combustion;

    Abstract : In the work presented here the attention has been focused on optimising sample preparation and analytical techniques for trace element determination, analytical quality assurance and environmental applications. Trace element concentrations in various environmental matrices were investigated using Energy Dispersive X-ray Fluorescence (EDXRF), Inductively Coupled Plasma Mass Spectro-metry (ICP-MS) and Cold Vapour Atomic Absorption Spectrometry (CV-AAS).

  4. 2. Toxicological studies of opiate-related death

    Author : Joakim Strandberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This thesis comprises studies on opiate overdose death, and focuses on evaluation of toxicological characteristics including the possible influence of abstinence and polydrug use for the fatal outcome. In order to identify and classify drug abusers, a screening method for several drugs of abuse was developed and applied on randomly selected autopsy cases. READ MORE

  5. 3. Mineral element contents in drinking water - aspects on quality and potential links to human health

    Author : Ingegerd Rosborg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; Naturvetenskap; Natural science; water treatment effects; hair concentrations; pH; magnesium; calcium; bicarbonate; drinking water; minerals;

    Abstract : Mineral elements in drinking water have been in focus for more than a decade, especially as the habit of drinking bottled water has increased, not the least among young people. Minerals in drinking water have become more important since minerals in food, especially in vegetables, have decreased substantially the last decades. READ MORE

  6. 4. Clinical and Genetic Studies of Hearing Impairment

    Keywords : Otorhinolaryngology; NF2; array-CGH; Meniere’s disease; PIK3C2G; X-linked; progressive; hearing impairment; Otorhinolaryngologi;

    Abstract : Monogenic disorders offer a possibility for studies of genetic disturbances in hearing impairment—a knowledge which could be essential for development of future treatment options. In this thesis, the underlying genetic disturbances in neurofibromatosis 2 (NF2) and familial Meniere’s disease (FMD) were evaluated, and familial X-linked hearing impairment was described from a clinical point of view.
