  1. 1. A strategy for ranking environmentally occuring chemicals

    Författare :Lennart Eriksson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QSAR; hazard ranking; statistical design; multivariate modelling; halogenated aliphatics; PCA; PLS;

    Sammanfattning : A systematic methodology for quantitative structure-activity relationship (QSAR) development in environmental toxicology is provided. The methodology is summarized in a strategy with six sequential steps. LÄS MER

  3. 2. Absorption non-uniformity characterisation and its impact on flexographic ink distribution of coated packaging boards

    Författare :Sofia Thorman; Li Yang; Göran Ström; Magnus Lestelius; Janet Preston; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid absorption; Absorption non-uniformity; Characterisation; Measurement technique; Print Mottle; Flexography; Coated packaging boards; Chemical Engineering; Kemiteknik;

    Sammanfattning : There are high demands on flexographic print quality to be sufficiently high and consistent in order to create a competitive packaging. At the same time the production efficiency need to be high. Printers thus need to achieve the same quality every time and quickly start-up new printing jobs. LÄS MER

  4. 3. Environmental and health hazards of chemicals in plastic polymers and products

    Författare :Delilah Lithner; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Towards Sustainable Use of Chemicals in the Textile Industry: How life cycle assessment can contribute

    Författare :Sandra Roos; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Toxicity; Textile; LCA; Chemicals; Impact assessment;

    Sammanfattning : The use of chemicals in the textile industry is a topic that has been given increasing attention in recent years. Hazardous chemicals are found in textile consumer products on a regular basis, and there is an increased awareness of the health and environmental impact caused by emissions of hazardous chemicals in the countries where textile production occurs.

  7. 5. Oxidation of fish lipids during gastrointestinal in vitro digestion

    Författare :Karin Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TBARS; HHE; salmon; lipids; TIM; fish; HNE; in vitro digestion; gastrointestinal; aldehydes; cod liver oil; n-3 PUFA; herring; lipid oxidation; MDA;

    Sammanfattning : Fish and many other marine organisms, contain long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), e.g. eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA and DHA has shown beneficial effects in diseases related to inflammatory processes, such as cardiovascular diseases. LÄS MER
