  2. 6. Atmospheric transport of persistent organic pollutants to aquatic ecosystems

    Author : Cecilia Agrell; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Temperature; Latitude; Deposition; PCB; Baltic Sea; Ekologi;

    Abstract : The load of persistent organic pollutants (POPs) is considered high in the Baltic ecosystem. The Baltic Sea spans over 12 latitudes and the regional differences in climate affect the behavior of POPs. READ MORE

  4. 7. Polychlorinated biphenyls and their metabolites in human blood : Method development, identification and quantification

    Author : Lotta Hofvander; Åke Bergman; Bo Jönsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PCB; polychlorinated biphenyls; metabolites; human blood; Environmental chemistry; Miljökemi;

    Abstract : PCBs are well known environmental pollutants. They are also precursors to metabolites, as the hydroxy-PCBs and the methylsulfonyl-PCBs. This thesis presents a validated methodology for analysis of PCB metabolites and a structural identification of 38 hydroxy-PCBs in human blood. READ MORE

  5. 8. The Otter (Lutra lutra) in Sweden : Contaminants and Health

    Author : Anna Roos; Jan Örberg; Björn Brunström; Katrin Lundstedt-Enkel; Susan Shaw; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Otter Lutra lutra ; PCB; DDT; PFAAs; reproduction; bone; time trends; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : In the 1950s the otter started to decline in numbers and distribution in Sweden and other parts of Europe. In 1972 a game law came into force, listing otter as a species that if found dead should be reported and sent to the authorities. The numbers of dead otters reported from different areas indicate population status and distribution. READ MORE

  6. 9. Analysis of PCBs with special emphasis on comprehensive two-dimensional gas chromatography of atropisomers

    Author : Mikael Harju; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; PCB; Atropisomers; Chiral; GC×GC; Enantiomeric barriers; Seal; polar; shape selective; Cyclodextrin; 2D; ECD; FID; TOF-MS; Comprehensive two-dimensional GC; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

    Abstract : There are 209 PCB congeners, 136 of which have been found in technical PCB mixtures and hence may be found in the environment as a result of either intentional or unintentional release. The identification and quantification of the congeners are difficult due to analytical bias from coeluting PCBs and other persistent organic pollutants. READ MORE

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

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

    Abstract : 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. READ MORE
