Brominated flame retardants (BFRs), polybrominated diphenyl ethers (PBDEs), and decabromodiphenyl ethane (DBDPE) were examined in household products in the Pearl River Delta, South China, including electronic appliances, furniture and upholstery, car interiors, and raw materials for electronics. The concentrations of PBDEs derived from penta-BDE mixture were much lower (<111 ng/g) than those for octa- and deca-BDE commercially derived PBDEs, with maximum values of 15,107 and 1,603,343 ng/g, respectively, in all the household products. Our findings suggest the recycling of old electronic products and their reuse might be also a potential important source of discontinued PBDEs to the environment. DBDPE was found in 20.0% of all the samples, ranging from 311 to 268,230 ng/g. PBDE congener profiles in both the household products and raw materials suggest that some less brominated BDEs in the environment may be derived from the decomposition of higher brominated PBDEs in PBDE-containing products in process of the manufacturing, use and/or recycling. Human exposure to PBDEs from household products via inhalation ranged from 175 to 612 pg/kg bw day, accounting for a small proportion of the total daily exposure via indoor inhalation. Despite the low deleterious risk associated with household products with regard to PBDEs, they are of special concern because of the relatively higher exposures observed for young children and further work is required.
溴化阻燃剂（BFRs）、多溴二苯醚（PBDEs）和十溴二苯乙烷（DBDPE）在中国南方珠江三角洲的家庭产品中进行了检测，包括电子设备、家具和室内装潢、汽车内饰以及电子材料。五溴二苯醚混合物衍生的 PBDE 浓度（<111ng/g）远低于商用八溴和十溴 PBDE（分别为 15、107 和 1603343ng/g），在所有家庭产品中均达到最大值。我们的研究结果表明，回收旧电子产品并重复使用它们可能也是环境中已停产的 PBDE 的一个潜在重要来源。在所有样本中，发现 20.0%的样本中含有 DBDPE，浓度范围为 311 至 268230ng/g。家庭产品和原材料中的 PBDE 同系物谱表明，环境中一些溴化程度较低的 BDE 可能来自于 PBDE 含量产品在制造、使用和/或回收过程中，较高溴化 PBDE 的分解。通过吸入途径从家庭产品中接触 PBDEs 的人体暴露量范围为 175 至 612pg/kg bw day，占室内吸入途径总暴露量的一小部分。尽管家庭产品中与 PBDEs 相关的低危害性风险与人类健康有关，但鉴于儿童的暴露水平相对较高，仍需特别关注。
