2. 1. Brominated natural products at different trophic levels in the Baltic Sea : Identification of polybrominated dioxins, hydroxylated and methoxylated diphenyl ethers

   Author : Anna Malmvärn; Lillemor Asplund; Åke Bergman; Bert van Bavel; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; polybrominated dibenzo-p-dioxins; hydroxylated polybrominated diphenyl ethers; methoxylated polybrominated diphenyl ethers; Baltic Sea; algae; natural production; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

   Abstract : Over time, the Baltic Sea has been contaminated by increasing discharges of pollutants from human activities. Persistent organic pollutants (POPs) have caused toxic effects in wildlife and excess of nutrients have led to eutrophication. READ MORE

4. 2. Polybrominated dibenzo-p-dioxins : Natural formation mechanisms and biota retention, maternal transfer, and effects

   Author : Kristina Arnoldsson; Peter Haglund; Patrik Andersson; Walter Vetter; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; polybrominated dibenzo-p-dioxins; PBDDs; Baltic Sea; uptake; retention; maternal transfer; metabolism; bioavailability; natural formation; precursor; bromoperoxidase; bromophenol; photochemical transformation; oxidative coupling; hydroxylated polybrominated diphenyl ethers; Chemistry; Kemi; analytisk kemi; Analytical Chemistry;

   Abstract : Polybrominated dibenzo-p-dioxins (PBDD) and dibenzofurans (PBDF) are a group of compounds of emerging interest as potential environmental stressors. Their structures as well as toxic responses are similar to the highly characterized toxicants polychlorinated dibenzo-p-dioxins. READ MORE

5. 3. Exposure and effects of naturally produced hydroxylated polybrominated diphenyl ethers in fish : Implications for Baltic Sea wildlife

   Author : Johan Gustafsson; Lillemor Asplund; Pim E.G. Leonards; Marja H. Lamoree; Robert Letcher; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecotoxicology; Metabolomics; OH-PBDE; Algae; Cyanobacteria; Natural products; Thiamine; Health; Biomarker; Seasonal variation; Perch; Zebrafish; Flame retardant; Mixture; 6-OH-BDE47; Energy metabolism; Endocrine disruption; Neurotoxicity; OXPHOS; Environmental Chemistry; miljökemi;

   Abstract : The aim of this thesis was to investigate if naturally produced hydroxylated polybrominated diphenyl ethers (OH-PBDEs) are causing negative health effects for Baltic Sea wildlife. In the laboratory, OH-PBDEs have shown to be potent disrupters of energy metabolism as well as endocrine disruptors and neurotoxins. READ MORE

6. 4. Hydroxylated polybrominat­ed diphenyl ethers in Baltic Sea biota : Natural production, food web distribution and biotransformation

   Author : Dennis Lindqvist; Lillemor Asplund; Walter Vetter; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; OH-PBDEs; Baltic Sea; Biosynthesis; Environmental fate; Wildlife exposure; Metabolism; Analytical methods; Ceramium tenuicorne; Blue mussel; Gammarus spp.; Stickleback; Perch; Grey Seal; miljökemi; Environmental Chemistry;

   Abstract : Hydroxylated polybrominated diphenyl ethers (OH-PBDEs) are naturally produced in aquatic ecosystems e.g. by algae. Many OH-PBDEs have been observed to be highly bioactive and to cause adverse effects through several pathways, e. READ MORE

7. 5. Organohalogen contaminants in humans with emphasis on polybrominated diphenyl ethers

   Author : Daiva Meironyté Guvenius; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The occurrence and distribution of organohalogen compounds, including polybrominated diphenyl ethers (PBDEs), in humans was investigated. For this purpose, the previously used method for analysis of organochlorine compounds was modified for the analysis of PBDEs and hydroxylated metabolites of polychlorinated biphenyls (OH-PCBs) in breast milk, matemal and cord blood plasma, liver and adipose tissue.
