  1. 11. 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

  5. 14. Towards understanding stable isotope signatures in stressed systems

    Författare :Caroline Ek; Elena Gorokhova; Katrine Borgå; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stable isotope analysis; trophic position; chemical exposure; oxidative stress; Daphnia magna; Gammarus spp.; Limecola balthica; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Stable isotope analysis (SIA) is a valuable tool in ecotoxicology because δ13C and δ15N may provide insights into the trophic transfer of contaminants in a food web. The relationship between a species’ trophic position (TP, determined from δ15N) and internal concentration of biomagnifying contaminants can be established and used for regulatory purposes. LÄS MER

  7. 15. When the Rubber Meets the Road -Ecotoxicological Hazard and Risk Assessment of Tire Wear Particles

    Författare :Anna Wik; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tire wear; tire particles; rubber; leaching tests; ecotoxicity tests; Daphnia magna; Ceriodaphnia dubia; Pseudokirchneriella subcapitata; Danio rerio; toxicity identification evaluation; detention ponds; hazard assessment; risk assessment;

    Sammanfattning : Large amounts of rubber particles are dispersed into the environment due to tire wear. The rubber contains a wide range of chemicals, including several of environmental concern. The purpose of this th.. LÄS MER
