  3. 22. Consumer Perception of Organic and Genetically Modified Foods : Health and Environmental Considerations

    Författare :Maria Magnusson; Per-Olow Sjödén; Ulla-Kaisa Koivisto Hursti; Liisa Lähteenmäki; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caring sciences; consumer perceptions; organic foods; genetically modified foods; food choice; health; environmental concern; Vårdvetenskap; Caring sciences; Vårdvetenskap;

    Sammanfattning : The aim was to study consumer attitudes to and perceptions of organic and genetically modified (GM) foods and factors influencing the purchase/non purchase of these two types of foods. Data were collected by two questionnaire surveys (random nation-wide samples of 2000 consumers, response rate 58% and 39% respectively) and one interview study (n=40). LÄS MER

  4. 23. Legacy persistent organic pollutants and chemicals of emerging concern in Sweden : from indoor environments to remote areas

    Författare :Seth Newton; Cynthia de Wit; Ulla Sellström; Per Larsson; Annika Jahnke; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; persistent organic pollutants; atmospheric deposition; arctic; flame retardant; POP; long range transport; miljökemi; Environmental Chemistry;

    Sammanfattning : Bulk atmospheric deposition samples were taken every two months for a year in 2009-2010 at two sites in northern Sweden and analyzed for a suite of legacy and emerging persistent organic chemicals including legacy organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs)  and novel flame retardants (NFRs).  To further investigate the urban occurrence and contribution to remote contamination of flame retardants, indoor air, ventilation system air, and dust were sampled in several microenvironments in Stockholm during the winter of 2012 for analysis of PBDEs, isomer-specific hexabromocyclododecane (HBCDD), and NFRs.

  5. 24. Electron transport in quaternized cross-linked poly(4-vinylpyridine) films containing trapped redox molecules : experimental and theoretical aspects that concern identification of electron translation mechanisms

    Författare :Henrik Larsson; Michael Sharp; Marcin Majda; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; charge transport; polymer film; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis deals with the identification of electron translation mechanisms in quaternized cross-linked poly(4-vinylpyridine) films containing trapped redox molecules. Experimental aspects, such as the determination of the total amounts of electroactive species within the films, measurements of electrochemical rate parameters and ellipsometric film thickness  evaluation, are discussed together with theoretical models that predict different mechanisms of charge transport.

  7. 25. Chocó challenges : communities negotiating matters of concern and care on Colombia’s margin

    Författare :Nicolas Acosta García; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Chocó is a remote and biodiverse region located on Colombia’s Northern Pacific Coast. The region is home to indigenous Embera and Afro-descendant communities. Both communities share and contest a legacy of colonisation, violence, dispossession and discrimination. LÄS MER
