Human exposure to brominated flame retardants (BFRs: decabromodiphenyl ether (BDE209), decabromodiphenyl ethane (DBDPE), hexabromobenzene (HBB), pentabromoethylbenzene (PBEB), pentabromotoluene (PBT), 1,2,3,4,5-pentabromobenzene (PBBz), and 2,3,5,6-tetrabromo-p-xylene (TBX)) in a brominated flame retardant production area (Weifang, Shandong Province, China) was estimated. Thirty food samples, 14 air samples, and 13 indoor dust samples were analyzed. BDE209 and DBDPE were the dominant BFRs in all samples. Higher alternative brominated flame retardant (including DBDPE, HBB, PBEB, PBT, PBBz, and TBX) concentrations were found in vegetables than in fish and meat; thus, plant-original foods might be important alternative BFR sources in the study area. The BDE209 and alternative BFR concentrations in air were 1.5×10(4) to 2.2×10(5) and 620 to 3.6×10(4) pg/m3, respectively. Mean total BFR exposures through the diet, inhalation, and indoor dust ingestion were 570, 3000, and 69 ng/d, respectively (16, 82, and 2% of total intake, respectively). Inhalation was the dominant BFR source except for DBDPE, for which diet dominated. BDE209 contributed 85% of the total BFR intake in the study area.
对中国山东省潍坊市一个溴化阻燃剂生产区的人类接触溴化阻燃剂（BFRs：十溴二苯醚（BDE209）、十溴二苯乙烷（DBDPE）、六溴苯（HBB）、五溴乙苯（PBEB）、五溴甲苯（PBT）、1,2,3,4,5 - 五溴苯（PBBz）和2,3,5,6 - 四溴对二甲苯（TBX））情况进行了估算。分析了30份食品样本、14份空气样本和13份室内灰尘样本。BDE209和DBDPE是所有样本中的主要溴化阻燃剂。在蔬菜中发现的替代性溴化阻燃剂（包括DBDPE、HBB、PBEB、PBT、PBBz和TBX）浓度高于鱼类和肉类；因此，植物源性食品可能是研究区域内替代性溴化阻燃剂的重要来源。空气中BDE209和替代性溴化阻燃剂的浓度分别为1.5×10⁴至2.2×10⁵和620至3.6×10⁴ pg/m³。通过饮食、吸入和摄入室内灰尘的平均总溴化阻燃剂暴露量分别为570、3000和69 ng/d（分别占总摄入量的16%、82%和2%）。除DBDPE外，吸入是主要的溴化阻燃剂来源，DBDPE的主要来源是饮食。在研究区域内，BDE209占总溴化阻燃剂摄入量的85%。
