  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. A Study in the Computational Complexity of Temporal Reasoning

    Författare :Mathias Broxvall; Peter Jonsson; Ulf Nilsson; Anders Haraldsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; temporal and spatial information; artificiell intelligens; algebra; tractable fragments; temporal formalisms; formalism STP; Computer science; Datavetenskap;

    Sammanfattning : Reasoning about temporal and spatial information is a common task in computer science, especially in the field of artificial intelligence. The topic of this thesis is the study of such reasoning from a computational perspective. LÄS MER

  4. 3. Effects of ozonated sewage effluents and pharmaceuticals in zebrafish (Danio rerio)

    Författare :Johannes Pohl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aquatic environment is the main destination for many organic pollutants originating from human activity. Pharmaceuticals are significant contributors to this pollutant cocktail. LÄS MER

  5. 4. Ozonation as sewage effluent treatment : toxicological effects in adult and embryonic zebrafish, Danio rerio

    Författare :Johannes Pohl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Pharmaceutical residues are not efficiently removed by current sewage treatment plant (STP) technologies. This allows for the release of pharmaceutical residues into the aquatic environment. Pharmaceuticals and their metabolites are problematic because they are designed to affect biological processes in non-target aquatic species. LÄS MER

  7. 5. Analytical method development for ultra-trace determination of human pharmaceuticals in aqueous samples. Assessing the performance of a sewage treatment plant

    Författare :Saioa Zorita; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecularly imprinted solid-phase extraction; Sample preparation; solid-phase extraction; membrane extraction; human pharmaceuticals; sewage treatment plant; steroid hormones;

    Sammanfattning : Research focus in environmental pollution has recently been extended from more classical environmental pollutants such as PCBs or pesticides to pharmaceuticals and steroid hormones, which are designed to be biologically active and enter the environment primarily through regular domestic use. Consequently, it is important to monitor these substances concentrations in the effluents of sewage treatment plants (STPs) and in the environment in order to evaluate their associated risks. LÄS MER
