1. 6. Models of the Distribution of Persistent Organic Pollutants in the Marine Environment

   Författare :N. Johan Persson; Dag Broman; Kevin Jones; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; persistent organic pollutants; mass balance models; fugacity models; eutrophication; PCDD F; PCB; PCN; soot carbon.; Environmental chemistry; Miljökemi;

   Sammanfattning : Persistent organic pollutants (POPs) is a group of chemicals that are toxic, undergo long-range transport and accumulate in biota. Due to their persistency the distribution and recirculation in the environment often continues for a long period of time. LÄS MER

3. 7. 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.

4. 8. 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

5. 9. Environmental Contaminants and Obesity

   Författare :Monika Rönn; P. Monica Lind; Lars Lind; Jan Örberg; Merete Eggesbø; Uppsala universitet; []
   Nyckelord :Fischer 344; rat; obesity; adipose tissue; persistent organic pollutants; POPs; bisphenol A; BPA; pesticides; dioxin; PCB; DDT; apo A-I; adiponectin; leptin; ghrelin;

   Sammanfattning : Obesity is a worldwide problem affecting both children and adults. Genetic, physiological, environmental, psychological, social and economic factors interact in varying degrees, influencing body weight and fat distribution and the progress of obesity. LÄS MER

7. 10. 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
