1. Azoles and Contaminants in Treated Effluents Interact with CYP1 and CYP19 in Fish
Abstract : 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. READ MORE

2. Organofluorine Mass Balance and Per- and Polyfluoroalkyl Substance Analysis of Environmental Samples and Human Blood
Abstract : 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. READ MORE

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

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