1. Polychlorinated biphenyls VII : studies on the synthesis of ¹⁴C-labelled and unlabelled chlorobiphenyls : identification of chlorobiphenyls present in technical PCB mixtures and in human adipose tissue
Sammanfattning : .... LÄS MER
2. Polychlorinated biphenyls and their metabolites in human blood : Method development, identification and quantification
Sammanfattning : 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. LÄS MER
3. Properties and analysis of dioxin-like compounds in marine samples from Sweden
Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs) have been assigned toxic equivalency factors (TEFs). These compounds are today routinely analysed with sophisticated analytical techniques. LÄS MER
4. Fate and transport of POPs in the aquatic environment : with focus on contaminated sediments
Sammanfattning : Persistent organic pollutants (POPs) are hydrophobic substances that readily sorb to organic matter in particles and colloids instead of being freely dissolved in the water phase. This sorption affects the bioavailability and environmental transport of the POPs. LÄS MER
5. Polychlorinated biphenyls (PCB) in a river ecosystem
Sammanfattning : Atmospheric deposition is one source of persistent pollutants such as polychlorinated biphenyls (PCB) in aquatic environments. Other point sources can also contribute to the PCB loadings in the water. LÄS MER
