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

   Författare :Anna Rotander; Bert van Bavel; Magnus Engwall; Jacob de Boer; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic; marine mammals; North Atlantic Ocean; POPs; temporal variations; NATURAL SCIENCES; NATURVETENSKAP; Environmental chemistry; 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

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

   Författare :Linda Linderholm; Åke Bergman; Maria Athanasiadou; Kristina Jakobsson; Myrto Petreas; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; POPs; PCB; DDT; PBDE; HCH; metabolites; human exposure; children s exposure; placental transfer; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

   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

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

   Författare :Tarmo Tiido; Malmö Reproduktionsmedicin; []
   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

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

   Författare :Samira Salihovic; Bert van Bavel; Lars Lind; Myrto Petreas; Örebro universitet; []
   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

7. 5. Advances in Mass Spectrometry for the Analysis of Emerging Persistent Organic Pollutants

   Författare :Lauren Gayle Mullin; Leo W. Y. Yeung; Ingrid Ericson Jogsten; Jean-François Focant; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass Spectrometry; Liquid Chromatography; Supercritical Fluid Chromatography; Ion Mobility; POPs; Electrospray Ionization;

   Sammanfattning : Mass spectrometry (MS) is a technique widely implemented for the measurement of environmental pollutants. A critical tool for the analysis of persistent organic pollutants (POPs) over several decades, MS as coupled with liquid and gas chromatography (LC and GC) techniques enables the analysis of emerging POPs.
