  1. 1. Occurrence and environmental risk assessment of antifouling paint biocides from leisure boats

    Författare :Maria Lagerström; Ann-Kristin Eriksson Wiklund; Erik Ytreberg; Kent Salo; Andrew Turner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antifouling paint; XRF; leisure boat; recreational boating; copper; zinc; tributyltin; organotin compounds; risk assessment; biocide; metals; release rate; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The use of biocidal antifouling (AF) paints is the most common way to prevent fouling on leisure boat hulls. The main aim of this thesis was to investigate the pathways through which AF biocides, past and present, may reach the environment through their use on leisure boats and to improve the risk assessment of biocidal AF paints intended for amateur use.

  3. 2. Management and Treatment of Organotin and Metal Contaminated Dredged Sediment

    Författare :Anna Norén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tributyltin TBT ; electrolysis; metals; stabilization and solidification S S ; life cycle assessment LCA ; dredged sediment; copper Cu ; multicriteria analysis MCA ; zinc Zn ; Fenton’s reagent;

    Sammanfattning : Modern society is dependent on international trade and most traded goods are transported by sea. To enable this, regular dredging must be done to maintain water depth in ports and waterways, resulting in large quantities of often contaminated sediment that must be handled. LÄS MER

  4. 3. Apoptosis in chronic inflammation, with specific reference to airway disease

    Författare :Malin Müller; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Apoptosis; asthma; chronic inflammation; lung; sarcoidosis; tributyltin TBT ;

    Sammanfattning : Mechanisms governing the normal resolution processes of inflammation in the lung are poorly understood, yet their elucidation may lead to a greater understanding of the pathogenesis of several pulmonary inflammatory disorders. The elimination of activated lymphocytes by apoptosis is one prerequisite for resolution, and knowledge concerning the role of apoptosis in chronic inflammation is still far from complete. LÄS MER

  5. 4. Assessing environmental and contaminant stressors in a benthic amphipod

    Författare :Therese Jacobson; Brita Sundelin; Tamara Galloway; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiple stressors; Reproduction; Temperature; Food; Parasites; Fenarimol; PFOS; TBT; Endocrine disruption; Ecdysteroids; Microsporidia; Microcosm; Crustacea; Amhipoda; Monoporeia affinis; Biology; Biologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Organisms in the aquatic environment encounter numerous stressors throughout their lifespan. Some of them are biotic such as food availability, predators and parasites. Others are abiotic and include shifting salinity and temperature change among others. LÄS MER

  7. 5. Bioaccumulation and biological effects of organic contaminants in Icelandic coastal waters

    Författare :Halldóra Skarphéđinsdóttir; Åke Granmo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Miljögifter; Marine Ecotoxicology; marin ekotoxikologi;

    Sammanfattning : In this thesis, studies on organic contamination from both diffuse and point sources in Icelandic waters are presented. The aim was to investigate bioaccumulation and biological effects of the contaminants or biomarkers, and their applicability in environmental marine coastal monitoring, especially in areas with moderate or low levels of contamination such as Iceland.
