  1. 1. Monitoring persistent organic pollutants (POPs) in sub-Arctic and Arctic marine mammals, 1984 - 2009

    Detta är en avhandling från Örebro : Örebro universitet

    Författare :Anna Rotander; Örebro universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic; marine mammals; North Atlantic Ocean; POPs; temporal variations; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Miljökemi; Environmental Chemistry;

    Sammanfattning : The Arctic has become an important indicator region for assessing persistence and bioaccumulation properties of persistent organic pollutants (POPs). This thesis is aimed at evaluating the occurrence of persistent halogenated POPs in seven species of sub-Arctic and Arctic marine mammals over a 25-year period. LÄS MER

  2. 2. Assessment of Environmental Pollutants in Humans from Four Continents Exposure levels in Slovakia, Guinea-Bissau, Nicaragua and Bangladesh

    Detta är en avhandling från Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Sammanfattning : Humans are continuously exposed to complex mixtures of anthropogenic chemicals. This thesis focus on human exposure to persistent organic pollutants (POPs). POPs ability to bioaccumulate and biomagnify together with the extensive historical use of POPs in e.g. LÄS MER

  3. 3. ENVIRONMENTAL CONTAMINANTS AND SPERM Y:X CHROMOSOME RATIO. Impact of androgen- and dioxin-related effects in vivo and in vitro

    Detta är en avhandling från Department of Clinical Sciences, Lund University

    Författare :Tarmo Tiido; Lunds universitet.; Lund University.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AR; polymorphisms; Sertoli cell; endocrine disruption; inhibitory cross-talk; Biomedicinska vetenskaper; Biomedical sciences; AHR; sperm Y:X chromosome ratio; sex ratio; POPs; TCDD;

    Sammanfattning : During the last decades, there has been concern that the environmental contaminants, such as POPs, may contribute to sex ratio changes in offspring of exposed populations. Accidental exposure to TCDD has been shown to be associated with fewer sons in men who were exposed in adolescence or earlier in life. LÄS MER

  4. 4. Development and application of high-throughput methods for analysis of persistent organic pollutants in human blood

    Detta är en avhandling från Örebro : Örebro universitet

    Författare :Samira Salihovic; Örebro universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human blood; POPs; Perfluoroalkylated substances; Structural isomers; Sample preparation; Column-switch; Mass spectrometry; Kemi; Chemistry;

    Sammanfattning : The general public is continuously exposed to a wide range of environmental pollutants. This thesis focuses on a group of anthropogenic chemicals referred to as persistent organic pollutants (POPs) that have been linked to various adverse health effects in humans. LÄS MER

  5. 5. Packed Column Supercritical Fluid Chromatography Applications in Environmental Chemistry

    Detta är en avhandling från Örebro : Örebro University

    Författare :Nicole Riddell; Örebro universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supercritical Fluid Chromatography; Mass Spectrometry; Ionization; POPs; APPI; APCI; chiral; achiral; packed column;

    Sammanfattning : Although gas and liquid chromatography have emerged as dominant separation techniques in environmental analytical chemistry, these methods do not allow for the concurrent analysis of chemically diverse groups of persistent organic pollutants (POPs). There are also a small number of compounds which are not easily amenable to either of these traditional separation techniques. LÄS MER
