  1. 16. Metal fate and sensitivity in the aquatic tropical vegetable Ipomoea aquatica

    Författare :Agneta Göthberg; Maria Greger; Hans Borg; M.N.V. Prasad; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquatic plants; vegetables; methyl mercury; metal accumulation; metal effects; thiol-rich peptides; Ipomoea aquatica; Plant physiology; Växtfysiologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The aquatic plant Ipomoea aquatica is a popular vegetable in Southeast Asia, often cultivated in nutrient rich and polluted waters. The overall aim of this thesis was to estimate potential risks for human health and reduced plant growth due to accumulation and toxicity of total-Hg, methyl-Hg, Cd and Pb. LÄS MER

  3. 17. Contaminated sediments: Methods to assess release and toxicity of organic chemical mixtures

    Författare :Lukas Mustajärvi; Anna Sobek; Jarkko Akkanen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sediment; Hydrophobic organic contaminants; Flux; Bioturbation; Passive sampling; Passive dosing; Mixture toxicity; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Bottom sediments around the world store large amounts of legacy hydrophobic organic contaminants (HOCs), forming mixtures of unknown chemical composition. Primary emissions to the environment of many HOCs have been reduced as a consequence of regulation. LÄS MER

  4. 18. New Approaches for Daphnia magna Toxicity Assessment

    Författare :Berkay Paylar; Per-Erik Olsson; Jana Jass; Solomon Asnake; Ajay Pradhan; Joachim Sturve; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Risk assessment; toxicogenomics; zinc; copper; machine learning;

    Sammanfattning : Risk assessment plays a crucial role in evaluating and managing the potential hazards and health effects associated with exposure to substances. In recent decades, the field of risk assessment has undergone significant expansion, embracing innovative approaches and methodologies. LÄS MER

  5. 19. Environmental, health, and safety assessment of chemical alternatives during early process design: The role of predictive modeling and streamlined techniques

    Författare :Gulnara Shavalieva; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LCA; EHS; CAMD; acute aquatic toxicity; phase-change solvents; Predictive modeling; carbon capture; knowledge extraction;

    Sammanfattning : Industrial chemicals are important for many aspects of modern life, though they can be harmful to the environment and human health. Environmental or safety concerns identified during the early design and selection of chemicals could motivate choices as to safer alternatives and process setups. LÄS MER

  7. 20. Fungal degradation patterns and toxicity of furfurylated wood

    Författare :Annica Pilgård; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Daphtox; Quantitative real-time PCR; Furfurylation; Microtox; Basidiomycota; Acetylation; Wood modification.; Daphnia magna; Thermal modification; Trametes versicolor; Decay; Vibrio fischeri;

    Sammanfattning : The demand for timber products is increasing with global population and affluence. Concerns regarding conventionally used toxic wood preservatives and the deforestation of tropical forests have become more prominent both socially and politically. Wood based products are generally recognised as an environmentally favourable raw material. LÄS MER
