2. 1. 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

4. 2. 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

5. 3. Occupational exposure to brominated flame retardants : With emphasis on polybrominated diphenyl ethers

   Author : Kaj Thuresson; Åke Bergman; Peter Fürst; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; occupational exposure; Brominated flame retardants; polybrominated diphenyl ethers; air and serum concentrations; decabromodiphenyl ether; Environmental chemistry; Miljökemi;

   Abstract : Brominated flame retardants (BFRs) are a diverse group of chemicals, which are used to slow down or inhibit the development of fires. BFRs are incorporated into a wide range of consumer products that are considered as potential fire hazards, such as TV-sets, household appliances, computers, and textiles. READ MORE

6. 4. Polybrominated diphenyl ethers and Tetrabromobisphenol A : Chemical synthesis, X-ray crystallography and Photochemical degradation

   Author : Johan Eriksson; Åke Bergman; Lars Eriksson; Mats Tysklind; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi;

   Abstract : In the 1960s’ several manmade chemicals were detected in the environment, far from their sources. The most well known, and most likely those with the largest impact on the society, were DDT and its related compounds, and PCBs. These anthropogenic compounds were characterised as persistent organic pollutants (POPs). READ MORE

7. 5. Polybrominated dibenzo-p-dioxins and furans : from source of emission to human exposure

   Author : Filip Bjurlid; Jessika Hagberg; Bert van Bavel; Ingrid Ericson Jogsten; Peter Haglund; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PBDD Fs; PCDD Fs; marine mammal; combustion; fire; human milk; occupational exposure;

   Abstract : Brominated flame retardants (BFRs), which are ubiquitous in modern life and the environment, are the major source for polybrominated dibenzo-p-dioxins and furans (PBDD/Fs). The knowledge about PBDD/Fs is lim-ited compared to other environmental pollutants, even though PBDD/Fs show similar toxicity as polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) which are considered to be among the most toxic man-made substances.
