Polybrominated diphenyl ethers (PBDEs) are used as flame retardants in numerous products, from which they are emitted to the environment, including house dust. House dust is a source of human exposure to these compounds by ingestion. The aim of this article was to determine the levels of selected PBDEs in the house dust and indicate their potential sources of origin. PBDE congeners: BDE-47, BDE-99, BDE-153 and BDE-209, were analyzed in 129 samples. The geometric mean levels (and 95% CIs) of the aforementioned congeners amounted to 3.8 (3.1-4.7) ng/g, 4.5 (3.5-5.6) ng/g, 2.2 (2.1-2.4) ng/g and 345 (269-442) ng/g respectively. BDE-209 was the dominant congener in the majority of tested samples. We found a statistically significant correlation between the concentrations of BDE-47 and the computer operating time per day (r - 0.18) and the living area (r - 0.20). Statistically significant higher levels of BDE-99 were found in homes where the floor was not replaced during the last 2 years.
多溴二苯醚（PBDEs）在众多产品中用作阻燃剂，这些产品会将其排放到包括室内灰尘在内的环境中。室内灰尘是人类通过摄入接触这些化合物的一个来源。本文的目的是测定室内灰尘中选定多溴二苯醚的含量，并指出其潜在来源。对129个样本分析了多溴二苯醚同系物：BDE - 47、BDE - 99、BDE - 153和BDE - 209。上述同系物的几何平均含量（及95%置信区间）分别为3.8（3.1 - 4.7）纳克/克、4.5（3.5 - 5.6）纳克/克、2.2（2.1 - 2.4）纳克/克和345（269 - 442）纳克/克。在大多数测试样本中，BDE - 209是主要的同系物。我们发现BDE - 47的浓度与每天电脑使用时间（r = 0.18）和居住面积（r = 0.20）之间存在统计学上的显著相关性。在过去两年未更换地板的家庭中，发现BDE - 99的含量在统计学上显著更高。
