Concentrations of nine organophosphate flame retardants (OPFRs) and eight polybrominated diphenyl ethers (PBDEs) were measured in samples of indoor dust (n = 85) and air (n = 45) from Australian houses, offices, hotels, and transportation (buses, trains, and aircraft). All target compounds were detected in indoor dust and air samples. Median ∑OPFRs concentrations were 40 μg/g in dust and 44 ng/m in indoor air, while median ∑PBDEs concentrations were 2.1 μg/g and 0.049 ng/m. Concentrations of FRs were higher in rooms that contained carpet, air conditioners, and various electronic items. Estimated daily intakes in adults are 14000 pg/kg body weight/day and 330 pg/kg body weight/day for ∑OPFRs and ∑PBDEs, respectively. Our results suggest that for the volatile FRs such as tris(2-chloroethyl) phosphate (TCEP) and TCIPP, inhalation is expected to be the more important intake pathway compared to dust ingestion and dermal contact.
在澳大利亚的房屋、办公室、酒店和交通工具(公共汽车、火车和飞机)中,采集了室内灰尘(n=85)和空气(n=45)样本,检测了其中 9 种有机磷阻燃剂(OPFRs)和 8 种多溴二苯醚(PBDEs)的浓度。所有目标化合物均在室内灰尘和空气样本中被检出。灰尘中∑OPFRs 的中位数浓度为 40μg/g,室内空气中为 44ng/m;∑PBDEs 的中位数浓度为 2.1μg/g 和 0.049ng/m。在有地毯、空调和各种电子产品的房间中,FRs 的浓度更高。成人的估计日摄入量分别为∑OPFRs 和∑PBDEs 的 14000pg/kg 体重/天和 330pg/kg 体重/天。研究结果表明,对于 TCEP 和 TCIPP 等挥发性 FRs,与灰尘摄入和皮肤接触相比,吸入可能是更重要的摄入途径。
