  1. 1. Azoles and Contaminants in Treated Effluents Interact with CYP1 and CYP19 in Fish

    Författare :Kristina Beijer; Ingvar Brandt; Björn Brunström; Henner Hollert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Azole; fungicide; chemical; CYP1A; CYP19; EROD; aromatase; effluent; STP; wastewater; fish; stickleback; rainbow trout; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Sammanfattning : Numerous contaminants are present in mixtures in the aquatic environment. Among these are the azoles, a group of chemicals that includes both pharmaceuticals and pesticides. Azole fungicides are designed to inhibit lanosterol 14-demethylase (cytochrome P450 (CYP) 51), while other azoles are intended to inhibit aromatase (CYP19), i.e. LÄS MER

  3. 2. Organofluorine Mass Balance and Per- and Polyfluoroalkyl Substance Analysis of Environmental Samples and Human Blood

    Författare :Rudolf Aro; Leo W. Y. Yeung; Anna Kärrman; Ulrika Eriksson; Christopher Higgins; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organofluorine mass balance; PFAS; extractable organofluorine; unidentified organofluorine; whole blood; surface water; effluent; sludge;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) have been linked to a range of negative health and environmental effects. Regulations limiting and/or banning the use of some of the legacy compounds have been introduced. Consequently, the production and use of PFAS has diversified. LÄS MER

  4. 3. Endocrine disrupting compounds in effluent waters : Chemical analysis to evaluate exposure of fish

    Författare :Maria Pettersson; Lillemor Asplund; Leif Kronberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Sammanfattning : The aim of this thesis was to investigate if endocrine disruption related to the release of estrogenic and/or androgenic substances via sewage treatment plant and pulp mill effluents is significant in Swedish waters. Chemical analysis of bile fluid in combination with measurement of biomarkers was used for the evaluation of internal exposure and effects in fish. LÄS MER

  5. 4. The link between kraft cooking and bleaching : influence on ECF bleachabiblity and bleaching effluent parameters

    Författare :Magnus Björklund; []
    Nyckelord :;

    Sammanfattning : The link between kraft cooking and bleaching was investigated, with the focus on how cooking kappa number, cooking conditions and pre-bleaching stages influence ECF bleachability and environmental parameters in the bleaching effluent. In one part of the study standard cooking conditions were used to produce birch and spruce pulps of different kappa numbers and then we studied how the AOX in the ECF bleaching effluent was affected by oxygen delignification, and hot acid stages.
