2. 1. Environmental fate of chemicals released from consumer products : Multimedia modelling strategies

   Author : Anna Palm Cousins; Michael McLachlan; Antonio Di Guardo; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multimedia fate model; urban model; PBDEs; phthalate esters; indoor environment; emissions; exposure; BDE 209; DINP; DEHP; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : The objective of this thesis was to assess the environmental fate and transport of chemicals emitted from consumer products through the development and application of modelling tools. The following hypotheses were tested: i) Multimedia fate models can be applied in a multistage assessment process to emerging chemicals when limited knowledge exists to identify the likely environmental fate and to direct further research; ii) the indoor environment acts as a source of anthropogenic substances in consumer products to the outdoor environment; and iii) chemical removal pathways in the indoor environment are important for the fate of organic chemicals in densely populated areas.

4. 2. Metabolism of some polychlorinated biphenyl and polybrominated diphenyl ether congeners in the rat

   Author : Anna Sandholm; Bert-Ove Lund; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

   Abstract : For the understanding of the metabolic fate of xenobiotics, in vivo studies are needed. In this thesis the metabolism of CB-28 and CB-77 and BDE-209 in the rat are determined. In addition, pharmacokinetic studies of CB-28 and BDE- 209 are included. The compounds were radiolabelled and their excretion and tissue distribution determined. READ MORE

5. 3. Gas chromatography and mass spectrometry of polybrominated diphenyl ethers

   Author : Jonas Björklund; Jacob De Boer; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Abstract : The aim of this thesis has been to develop accurate and sensitive analytical methods for the determination of polybrominated diphenyl ethers (PBDEs). It focuses on the development and optimization of gas chromatographic and mass spectrometric analysis of PBDE. READ MORE

6. 4. Levels of brominated flame retardants in humans and their environment : occupational and home exposure
