It is possible that brominated dibenzodioxins and -furans are formed in trace levels during the preparation of technical bromoether products 1-2- Dumler (ref. 12) and others (ref. 17) have found PBDD/F in the ppm range in commercial samples of decabromodiphenyl ether. A more recent and advanced study has been... 

Anaerobic dehalogenation has also been observed in aromatic ethers including polychlorinated dibenzo[l,4]dioxins (Fennell et al. 2004 Yoshida et al. 2005). The anaerobic debromination of decabromodiphenyl ether is considered here since it is analogous to the dehalogenation of polyhalogenated biphenyls.

Similarly, toluene suspensions of the polystyrene housing of TV sets were examined by means of TPPy-FTMS (300-1200 K) [224], Diphenylether (DPE) was evidenced by peaks at m/z 141, 142 and 170 and decabromobiphenyl (DBBP) by m/z 943 and 864. Decabromodiphenyl ether (DBDPE) was recognised by thermal degradation products around m/z 800...

These models have been applied to different scenarios, mainly for two chemicals DeBDE (decabromodiphenyl ether) and Pb (lead). The input data to the models are based on the SFA investigations described above. 

There is a huge variety of PBDEs considering that there might be from one to ten bromine atoms bound to the diphenyl ether molecule. Among all the PBDEs, the commercial mixtures of decabromodiphenyl ether (deca-BDE), octabromodiphenyl ether (octa-BDE) and pentabromodiphenyl ether (penta-BDE) are the products that are most found in the environment. Related to octa-BDE and penta-BDE mixtures, their commercial use was banned in the European Union in 2004 and that year their leading manufacturers in North America stopped producing them on a voluntary basis [2], Regarding the deca-BDE mixture, since July 2008, its use has been...

In an unprecedented step, the European Parliament has voted to ban two chemicals for which risk assessments are still pending. The chemicals, octabromodiphenylether and decabromodiphenyl ether, were lumped together with penta-BDE during a debate on the EC s proposed ban on that chemical, which is based on a completed risk assessment. All three chemicals are used as flame retardants. Parliamentarians backed the call to extend a ban on penta-BDE to octa-BDE, which is used in office equipment and domestic electrical appliances, by mid-2003. It is claimed that initial results of the ongoing risk assessments already indicate that the chemical is an environmental and public health hazard. MEPs have set a 2006 deadline for banning deca-BDE, adding that the ban should not come into force if the final results of the risk assessment show that deca-BDE is harmless. EUROPEAN PARLIAMENT...

Decabromodiphenyl ether (BDE-209) is a major industrial product from the polybrominated diphenyl ethers used as flame retardants derivatives of this product have been detected in the environment. After exposure to the land surface, these contaminants adsorb on soil materials and may reach the atmosphere as particulate matter these particulates are subsequently subject to photolytic reactions. In this context, Ahn et al. (2006) studied photolysis of BDE-209 adsorbed on clay minerals, metal oxides, and sediments, under sunhght and UV dark irradiation. Dark and light control treatments during UV and sunlight irradiation showed no disappearance of BDE-209 during the experiments. Data on half-lives and rate constants of BDE-209 adsorbed on subsurface minerals and sediments, as determined by Ahn et al. (2006) and extracted from the literature, are shown in Table 16.6.
