4- Bromodiphenyl ether PBDE

The term brominated flame retardant (BFR) incorporates more than 175 different types of substances, which form the largest class of flame retardants other classes are phosphorus-containing, nitrogen-containing, and inorganic flame retardants (Bimbaum and Sttaskal 2004). The major BFR substances in use today (depicted in Fig. 4.6) are tetrabromobisphenol A (TBBPA), hexabromocyclododecane (HBCD), and mixtures of polybrominated diphenyl ethers (PBDEs) (namely, deca-bromodiphenyl ether (DBDE), octabromodiphenyl ether (OBDE), and pentabro-modiphenyl ether (pentaBDE)). 

EPA requires that companies that transport, store, or dispose of /7-bromodiphenyl ether (a particular PBDE compound) follow the rules and regulations of the federal hazardous waste management program. EPA also limits the amount of /7-bromodiphenyl ether put into publicly owned waste water treatment plants. To minimize exposure of people to /7-bromodiphenyl ether, EPA requires that industry tell the National Response Center each time 100 pounds or more of /7-bromodiphenyl ether have been released to the environment. 

Synonym BDE-2, PBDE-2, l-bromo-3-phenoxybenzene, m-bromophenyl phenyl ether, 3-bromophenyl phenyl ether, 3-phenoxybromobenzene, 3-phenoxyphenyl bromide, m-bromodiphenyl ether, m-phenoxybromobenzene, m-phenox-yphenyl bromide... 

Mass Spectrum The ability of the present methods to identify PBDEs and deca-bromodiphenyl ether (decaBDE) in the plastic samples that contain several BFRs.
