  1. 6. Systemic effects of occupational exposure to arsenic : with special reference to peripheral circulation and nerve function

    Författare :Birgitta Json Lagerkvist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arsenic toxicity; Cold-induced vasospasm; Finger systolic pressure; Nerve conduction velocity; Occupational exposure; Raynaud s phenomenon; Serotonin antagonist;

    Sammanfattning : Smelter workers who were exposed to air-borne arsenic for a mean of 23 years, and age-matched referents, were examined with clinical, physiological, and neurophysiological methods. Exposure to arsenic in workroom air was estimated to have been around the Swedish occupational limits, which were 500 yg/m before 1975 and 50 yg/ra thereafter. LÄS MER

  3. 7. Environmental factors and p53 mutation spectrum in lung cancer

    Författare :Anna Bessö; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Lung cancer; p53; radon; tobacco smoking; arsenic; environmental tobacco smoke; ETS; case-only study; case-control study;

    Sammanfattning : The use of molecular biomarkers, such as mutations in the p53 gene, has raised expectations for improving the resolution power in epidemiological studies. In this thesis we assessed the influence of smoking, environmental tobacco smoke (ETS), residential radon and arsenic on the p53 mutation prevalence and spectrum in lung tumors. LÄS MER

  4. 8. Cadmium exposure and risk of kidney effects and bone fractures : population-based studies in England and Sweden

    Författare :Laura D K Thomas; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cadmium (Cd) is a toxic metal with no beneficial biological function. The dissemination of cadmium to the surface environment, by industrial and agricultural practices, has led to increased human exposure. LÄS MER

  5. 9. ³²P-postlabelling analysis of DNA adducts in fish as a biomarker of genotoxic exposure

    Författare :Gunilla Ericson; Tracy K Collier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoologisk ekologi; Animal Ecology;

    Sammanfattning : The 32P-postlabelling assay was used for analysis of hydrophobic DNA adducts in fish as a biomarker of genotoxic exposure. DNA adducts were analysed in perch (Perca fluviatilis) and northern pike (Esox lucius), two relatively stationary fish species which are common in Swedish freshwater systems and along the Baltic coast.

  7. 10. Leaching of water-granulated iron silicate slags and their compounds : A study of synthetic and industrial slag systems

    Författare :Jakob Kero Andertun; Fredrik Engström; Caisa Samuelsson; Pasi Peltola; Bart Blanpain; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Copper smelter slag is a residue product of the pyrometallurgical extraction of copper. Due to its physical properties, the iron silicate type of copper smelter slag has many possible application areas, e.g., different aggregates and abrasives. LÄS MER
