  1. 1. Innovative Bioreactors for the Degradation of Polycyclic Aromatic Hydrocarbons

    Författare :Benoit Guieysse; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Bioteknik; Biotechnology; PAH; degradation; aromatic; contaminant; pollutant; bioreactor; organic pollutant; kontroll av utsläpp; Miljöteknik; pollution control;

    Sammanfattning : The development of biological reactors for the treatment of toxic and recalcitrant organic pollutants is a complex task. Firstly, microbial inoculation, acclimation and selection must be optimized to provide the best microflora possible. LÄS MER

  3. 2. Algal-Bacterial Photobioreactors for the Degradation of Toxic Organic Pollutants

    Författare :Raul Munoz; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; symbiosis.; nutrient removal; heavy metals removal; Algal-bacterial systems photobioreactors; toxic organic pollutants;

    Sammanfattning : The aerobic biodegradation of toxic organic volatile contaminants is always limited by the low aqueous solubility of O2. Therefore, intensive bubbling or surface aeration is required to supply the bacterial community with sufficient O2 to carry out pollutant mineralization. This can cause the hazardous volatilization of toxic volatile contaminants. LÄS MER

  4. 3. Analysis of Perfluoroalkyl Acids in Swedish Biota : Temporal trends, tissue distribution and toxicity

    Författare :Katrin Holmström; Urs Berger; Gregg Tomy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; PFOS; PFAS; pollutant; Baltic guillemot; peregrine falcon; Monoporeia affinis; time trend; toxicity; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Perfluorinated alkyl acids (PFAS) are ubiquitous environmental contaminants. They are found in high concentrations in top predators worldwide, with perfluorooctane sulfonate (PFOS) as the predominant compound. LÄS MER

  5. 4. Cumulative assessment of persistent organic pollutant toxicity in vivo

    Författare :Emma Westerholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Humans are continuously exposed to a multitude of compounds present in the environment and in food. A major challenge in risk assessment is to determine the degree of exposure to multiple chemicals and the hazards associated with such combined exposure. LÄS MER

  7. 5. Biotechnological treatment of chlorophenol-contaminated water

    Författare :Hamid Zilouei; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; Cell-based biosensor; Fluorescence in situ hybridization; Bacterial community; Two-liquid phase partitioning bioreactor; Photolysis pretreatment; Biomonitoring; Fixed-biofilm reactors; Toxic organic pollutant; Biodegradation;

    Sammanfattning : Widespread presence of toxic and persistent pollutants in the environment, even at low concentrations, causes risks of adverse effects to human health and the ecosystem. Biological methods for treatment of water streams and removal of persistent pollutants are of great interest due to their simplicity, low cost, and mild operational conditions without harmful by-products.
