The study of not only main flame retardants but also of related degradation products or impurities has gained attention in the last years and is relevant to assess the safety of our consumer products and the emission of potential contaminants into the environment. In this study, we show that plastics casings of electric/electronic devices containing TBBPA contain also a complex mixture of related brominated chemicals. These compounds were most probably coming from impurities, byproducts, or degradation products of TBBPA and TBBPA derivatives. A total of 14 brominated compounds were identified based on accurate mass measurements (formulas and tentative structures proposed). The formulas (or number of bromine elements) for 19 other brominated compounds of minor intensity are also provided. A new script for the recognition of halogenated compounds based on combining a simplified isotope pattern and mass defect cluster analysis was developed in R for the screening. The identified compounds could be relevant from an environmental and industrial point of view.
近年来，人们不仅关注主要阻燃剂，还关注相关降解产物或杂质的研究，这对于评估我们消费产品的安全性以及潜在污染物排放到环境中的情况具有重要意义。在这项研究中，我们表明含有 TBBPA 的电子/电气设备的塑料外壳还含有复杂的相关溴化化学品混合物。这些化合物很可能来自 TBBPA 和 TBBPA 衍生物的杂质、副产物或降解产物。基于精确质量测量（提出的公式和暂定结构），共鉴定出 14 种溴化化合物。还提供了其他 19 种低强度溴化化合物的公式（或溴元素数量）。开发了一种新的脚本，用于在 R 中基于简化的同位素模式和质量缺陷聚类分析来识别卤化化合物，用于筛选。从环境和工业角度来看，这些已识别的化合物可能具有相关性。
