DecaBDE is the most widely used PBDE globally (ATSDR 2015; EPA 2009). The production of octaBDE and pentaBDE in the United States ceased PBDE is still under investigation, research has established that it is persistent, bioaccumulative, and toxic. There is evidence that PBDE can cause neurotoxic effects similar to the now-banned polychlorinated biphenyls (PCB). Just like PCBs, there are 209 PBDE congeners (Fig. 1), and they are named in … PBDE 28. Molecular Formula C 12 H 7 Br 3 O; Average mass 406.895 Da; Monoisotopic mass 403.804688 Da; ChemSpider ID 10239063 For example, the PBDE congener, 2,2',4,4'-tetraBDE may be referred to as BDE 47 in this document. The identities of several PBDE congeners are shown in Table 4-1 (WHO 1994a, 1994b).

U.S. production of some widely used PBDEs ended as of 2006, and the last major PBDE mixture is due to be phased out by the end of 2013. Polybrominated diphenyl ethers (PBDEs) have been widely used to flame-retard products common in homes and the workplace, and subsequently, they have become widely dispersed in the environment. Polybrominated diphenyl ethers (PBDE), which belong to a class of brominated hydrocarbon and are sometimes likened to brominated flame retardant (BFR) chemicals, have been widely utilized in the United States since the 1970s. Polybrominated diphenyl ethers (PBDEs) are used in large quantities as flame-retardant additives in a number of commercial products. Biomonitoring data show that, in recent years, PBDE concentrations have increased rapidly in the bodies of wildlife and humans. 2009 PBDE Flame Retardant Legislation On December 17, 2009, the principal manufacturers of decaBDE, Albemarle Corporation and Chemtura Corporation, and the principal importer, ICL Industrial Products, Inc., announced their commitment to a three-year phase-out of decaBDE. izing PBDE additives in polymers since the desire is not so much the complete separation as it is the overall composition and contribution of the various isomers [5 PBDE 28.

DecaBDE is the most widely used PBDE globally (ATSDR 2015; EPA 2009). The production of octaBDE and pentaBDE in the United States ceased PBDE is still under investigation, research has established that it is persistent, bioaccumulative, and toxic.

Pentabromodiphenyl ether is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers. Because of their toxicity and persistence, their industrial production is to be eliminated under the Stockholm Convention, a treaty to …

Det finns mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, okta-, nona- och dekaBDE, där det maximala antalet bromatomer är tio. PBDE delas också upp med avseende på bromatomernas placering på fenylringarna. Varje variant kallas en kongener och har ett eget nummer. degrade higher brominated PBDE, but may lead to the formation of less-brominated, more toxic congeners (He and others 2006; Lee and He 2010).

They are chemically related to polychlorinated biphenyls and are thought to have similar biological toxicity.

Medical Evaluation of PBDE exposure PBDEs can be measured in human blood, body fat and breast milk for epidemiological studies. However, for the individual patient, obtaining PBDE levels are not accessible or useful clinical tests. They are prohibitively expensive and have no interpretable reference ranges for clinical outcomes.

Animal studies have shown that PBDE exposure during pregnancy and after birth caused problems with brain development in offspring. These studies observed problems with learning, memory, and behavior in mice and rats. Animal studies also found that PBDEs can alter thyroid and other hormone levels.
