调查了2008年日本市场上电子设备、窗帘、壁纸、建筑材料等新型消费品中传统溴化阻燃剂（BFR）和有机磷酸盐阻燃剂（OPFR）的浓度。尽管X射线荧光分析表明，电子设备的某些部件含有按重量百分比计浓度的溴，但本研究中分析的溴化阻燃剂不能完全解释溴含量，其中包括多溴二苯醚、十溴二苯基乙烷、四溴双酚A、多溴苯酚和六溴环十二烷。这些结果表明可使用替代溴化阻燃剂，如新开发的从三溴苯酚、四溴双酚A衍生的配方。或两者在分析的11种OPFR中，磷酸三苯酯在所有研究的产品中以最高浓度存在，这表明使用缩合型OPFR作为替代阻燃剂，因为它们含有磷酸三苯酯作为杂质。在所有样品中均未检测到磷酸三丙酯：仅在某些组分中检测到低浓度的磷酸三甲酯、三（2-丁氧基乙基）磷酸三丁酯和磷酸三（1，3-二氯-2-丙基）酯。请注意，本研究中评估的所有消费品也含有传统的溴化阻燃剂，其含量不足以赋予阻燃性，这意味着含有全球关注的溴化阻燃剂的回收塑料材料的掺入。(C)2011 Elsevier B.

The concentrations of traditional brominated flame retardants (BFRs) and organophosphate flame retardants (OPFRs) in new consumer products, including electronic equipment, curtains, wallpaper, and building materials, on the Japanese market in 2008 were investigated. Although some components of the electronic equipment contained bromine at concentrations on the order of percent by weight, as indicated by X-ray fluorescence analysis, the bromine content could not be fully accounted for by the BFRs analyzed in this study, which included polybrominated diphenylethers, decabromodiphenyl ethane, tetrabromobisphenol A, polybromophenols, and hexabromocyclododecanes. These results suggest the use of alternative BFRs such as newly developed formulations derived from tribromophenol, tetrabromobisphenol A. or both. Among the 11 OPFRs analyzed, triphenylphosphate was present at the highest concentrations in all the products investigated, which suggests the use of condensed-type OPFRs as alternative flame retardants, because they contain triphenylphosphate as an impurity. Tripropylphosphate was not detected in any samples: and trimethylphosphate, tributyl tris(2-butoxyethyl)phosphate, and tris(1,3-dichloro-2-propyl)phosphate were detected in only some components and at low concentrations. Note that all the consumer products evaluated in this study also contained traditional BFRs in amounts that were inadequate to impart flame retardancy, which implies the incorporation of recycled plastic materials containing BFRs that are of global concern.
