Description

Polybrominated diphenyl ethers (PBDEs) are a group of additive brominated flame retardants (BFRs) that are widely used in electronic equipment, insulation material, and furniture. The major commercial mixtures of PBDEs are composed of deca-BDE in Japan. The rapid increase in the use of BFRs has also raised the level of environmental concern about polybrominated chemicals such as polybrominated biphenyls (PBBs) and polybrominated dibenzo-p-dioxins/furans (PBDDs/DFs), which are present as low-level impurities in some commercial mixtures of BFRs and are produced upon their combustion. PBDDs/DFs are also formed, for example, when plastics that contain BFRs are heated during the welding of mats or the melting of polymers. The thermal formation of PBDDs/DFs from BFRs is considered to be a serious issue. In the present study, we determined the concentrations of PBDDs/DFs, PBBs, PBDEs, and polybrominated benzenes (PBBzs) in flue gas and fly ash from combustion of plastics containing deca-BDE. In addition, the concentrations of extractable organic bromine (EOBr) in flue gas and fly ash were determined using combustion ion chromatography (CIC) and applied in a study to evaluate contributions of known brominated chemicals such as PBDEs and PBBs to extractable organic bromine.
