  2. 16. Chlorinated Paraffins: improved understanding of their bioaccumulation and toxicity in Daphnia magna

    Author : Mafalda Castro; Magnus Breitholtz; Anna Sobek; Elena Gorokhova; Lillemor Asplund; Martin Scheringer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chlorinated paraffins; POPs; bioaccumulation; toxicity; ecotoxicology; aquatic toxicology; daphnia magna; liposomes; passive dosing; hydrophobic; mixtures; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Chlorinated paraffins (CPs) are industrial chemicals, mainly used as flame retardants, plasticizers and metal cutting fluids. Their production has reached historically high levels in the last decade, with an annual production exceeding one million tonnes. READ MORE

  4. 17. Fungal degradation patterns and toxicity of furfurylated wood

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

    Abstract : 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. READ MORE

  5. 18. Application and interpretation of biomarkers in ecotoxicology - from molecular to individual level responses

    Author : Sara Furuhagen; Elena Gorokhova; Carlos Barata; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomarkers; oxidative stress; ORAC; reproduction; Daphnia magna; toxicity; environmental stress; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The use of biomarkers is considered a promising alternative, or complement, to traditional ecotoxicological assays. Toxic effects are often initially manifested at the molecular or biochemical level, biomarkers are therefore used as sensitive indicators of toxic exposure. READ MORE

  6. 19. Integrative approaches in ecotoxicological testing: Implications for biomarker development and application

    Author : Sara Furuhagen; Elena Gorokhova; Magnus Breitholtz; Lars Förlin; Ann-Kristin Eriksson Wiklund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomarker; oxidative stress; Daphnia magna; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Ecotoxicology aims to understand toxic effects of chemicals in the environment. Effects can be observed at different levels of the biological organization, from molecular to ecosystem level. READ MORE

  7. 20. Environmental and health hazards of chemicals in plastic polymers and products

    Author : Delilah Lithner; Göteborgs universitet; []
    Keywords : plastics; plastic products; plastic polymers; consumer products; environmental hazards; environment; health hazards; human health; hazard ranking; hazard assessment; chemical ranking; hazard identification; hazard classifications; hazardous chemicals; hazardous substances; toxic substances; monomers; polymers; toxicity; acute toxicity; toxicity tests; Daphnia magna; Toxicity Identification Evaluation; TIE; leaching; leachates; product leachates; leaching tests; plastic materials; plastic;

    Abstract : Plastics are extremely diverse in terms of chemical composition, properties and possible applications, and are widely distributed in the society and the environment. In the last 15 years the global annual production has doubled, reaching 245 million tons in 2008. READ MORE
