16. Comparison of experimentally and theoretically determined oxidation and photochemical transformation rates of some organohalogens to promote prediction of persistence
Abstract : The diversity of choices we have to make everyday influence our environment and ourselves in more ways than most of us realise. Anthropogenic substances, such as flame retardants, date back as early as 450 BC when the Egyptians used alum to reduce flammability. READ MORE

17. Cats as a biomarker for exposure to POPs in home environments : – with focus on brominated chemicals and associations to feline hyperthyroidism
Abstract : In this thesis, body burden of brominated chemicals such as polybrominated diphenyl ethers (PBDEs) and brominated phenolic substances are explored. The external exposure of cats to these compounds from house dust and their food was also investigated. READ MORE

18. Bis(4-chlorophenyl) sulfone and PCB methyl sulfone metabolites : Trends and chirality in the Baltic Sea environment
Abstract : The Baltic Sea was earlier identified as a highly polluted brackish water body and still is. The high concentrations of polychlorinated biphenyls (PCBs), p,p’-DDT and related compounds led to severe effects on several species in the Baltic region. READ MORE

19. Hydrolysis and photolysis of brominated flame retardants and some traditional persistent organic pollutants : Reactivity as a tool in fate assessement of chemicals
Abstract : An organic compound that remains in the environment for a long time is regarded as a persistent organic pollutant (POP). Still, persistency is not a well defined property with a firm definition. Instead it is a conceptual property of chemicals for which DDT and PCB are typical representatives. READ MORE

20. Organohalogen contaminants in Greenland shark (Somniosus microcephalus)
Abstract : The remote sub-Arctic/Arctic environment has due to human activities become a sink for organohalogen contaminants (OHCs). These OHC include traditional contaminants such as polychlorinated biphenyls (PCBs), DDTs and technical mixtures of polybrominated diphenyl ethers (PBDEs), all included in the Stockholm Convention list of persistent organic pollutants (POPs).
