  1. 36. Brominated natural products at different trophic levels in the Baltic Sea : Identification of polybrominated dioxins, hydroxylated and methoxylated diphenyl ethers

    Författare :Anna Malmvärn; Lillemor Asplund; Åke Bergman; Bert van Bavel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polybrominated dibenzo-p-dioxins; hydroxylated polybrominated diphenyl ethers; methoxylated polybrominated diphenyl ethers; Baltic Sea; algae; natural production; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Sammanfattning : Over time, the Baltic Sea has been contaminated by increasing discharges of pollutants from human activities. Persistent organic pollutants (POPs) have caused toxic effects in wildlife and excess of nutrients have led to eutrophication. LÄS MER

  3. 37. Waste incineration residues : Persistent organic pollutants in flue gas and fly ash from waste incineration

    Författare :Eva Weidemann; Lisa Lundin; Stellan Marklund; Jean-Francois Boily; Henrik Bristav; Kees Olie; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MSW; PCDD; PCDF; PCN; PCB; POP; formation; degradation; case study; flue gas sampling thermal treatment; fly ash; surface characterization;

    Sammanfattning : Modern societies produce large quantities of municipal solid waste (MSW), which is commonly disposed of by incineration. This has several advantages: it reduces the waste’s volume and sterilizes it while also enabling energy recovery. LÄS MER

  4. 38. Legacy and emerging pollutants in pristine and polluted boreal catchments

    Författare :Anh Minh Nguyen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Persistent organic pollutants (POPs) are bioaccumulative chemicals that are ubiquitously and globally distributed in the environment. Several species of POPs have been studied extensively and are continuously being monitored in various environmental matrices for decades. LÄS MER

  5. 39. Contaminated organic sediments of anthropogenic origin: impact on coastal environments

    Författare :Anna Apler; Ian Snowball; Sarah Josefsson; Lovisa Zillén; Magdalena Kuchler; Jonas Gunnarsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiberbank; fiber-rich sediment; metals; persistent organic pollutants; pore water; bottom water; dispersal; sorption; pulp and paper; chemostratigraphy; Anthropocene; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Sammanfattning : The Baltic Sea is negatively affected by legacy pollutants such as metals and persistent organic pollutants (POPs) that are known to have adverse effects on living organisms, including, humans and were banned decades ago. This thesis addresses the dispersal of these pollutants from heavily contaminated, cellulose-rich sediments of industrial origin in the Ångermanälven river estuary in northern Sweden. LÄS MER

  7. 40. Epididymal and accessory sex gland function and semen quality

    Sammanfattning : Infertility, defined as the inability to conceive after one year of unprotected regular intercourse, affects up to 15% of all couples of reproductive age. The infertility can originate from female, male or both partners. In up to 50% of the affected couples, a male factor is the cause of infertility. LÄS MER
