    Sammanfattning : Large numbers of samples often need to be prepared and analysed in surveys of organic pollutants in the environment, but while the methods commonly used in such surveys can provide abundant detail they are generally costly, time-consuming and require large amounts of resources, so there is a need for simpler techniques. The work underlying this thesis assessed the potential utility of more convenient sample preparation and bioanalytical techniques for rapidly screening various environmental matrices that could be useful complements to higher resolution methods.

    Sammanfattning : Wastewater treatment plants in Sweden are facing a great challenge due to the prohibition of depositing organic waste which gained legal force in January 2005. Biological and commercial available alternatives to disposal are composting and anaerobic digestion. LÄS MER

  4. 3. Bioassay analysis of dioxin-like compounds : response interactions and environmental transformation of Ah receptor agonists

    Författare :Helena Olsman; Magnus Engwall; John P. Giesy; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioassay; dioxin-like; Ah receptor; Biology; Biologi; Biology; Biologi;

    Sammanfattning : Dioxin-like compounds mediate their toxicity by binding to the aryl hydrocarbon receptor (AhR) and through this receptor a cascade of biochemical and toxic events are triggered. Mechanism-specific dioxin bioassays utilise the AhR coupled induction of endogenous CYP1A proteins or reporter gene systems for detection of dioxin-like compounds and other AhR ligands. LÄS MER
