Fifteen polybrominated diphenyl ethers (PBDEs) and eighteen non-PBDEs were measured in 116 dust samples collected from homes in Vancouver, Canada during 2007-2008 as part of the Chemicals Health and Pregnancy (CHirP) study. The highest concentrations of PBDEs in house dust were observed for BDE 209, with a median concentration of 1350 ng/g. This is about two times greater than the median concentration of the PentaBDE (represented by the most abundant compounds in this formulation, ΣBDE 47, 99 and 100). In the case of non-PBDE FRs, a detection frequency between 81% and 100% was observed for nine analytes including: HBCD, BTBPE, BEHTBP, EHTBB, HBB, PBTO, PBBe, ATE and DP. The high detection of new FRs in indoor environments reflects their ubiquitous presence in indoor environment due to regulation of the PBDEs. Exposure to FRs are estimated based on these data for adults and toddlers.
2007-2008 年期间，作为化学品健康与妊娠（CHirP）研究的一部分，在加拿大温哥华的 116 户家庭中收集了 116 个灰尘样本，对其中的 15 种多溴二苯醚（PBDEs）和 18 种非 PBDE 进行了测量。在房屋灰尘中，BDE-209 的浓度最高，中位数浓度为 1350ng/g。这大约是五溴二苯醚（由该配方中含量最丰富的化合物 ΣBDE-47、99 和 100 表示）中位数浓度的两倍。在非 PBDE FRs 的情况下，9 种分析物（包括 HBCD、BTBPE、BEHTBP、EHTBB、HBB、PBTO、PBBe、ATE 和 DP）的检测频率在 81%到 100%之间。新的 FRs 在室内环境中的高检出率反映了它们由于 PBDEs 的法规而普遍存在于室内环境中。根据这些数据，对成人和幼儿的 FRs 暴露情况进行了估计。
