We used personal air samplers to measure indoor air exposure to polybrominated diphenyl ethers (PBDEs) for 20 residents of the Greater Boston Area (Massachusetts). Area air measures were simultaneously collected from two rooms in each participant's home. Total personal air concentrations (particulate + vapor) were 469 pg/m3 for non-209 BDEs and 174 pg/m3 for BDE 209, significantly higher than bedroom and main living room concentrations (p = 0.01). The ratio of personal air to room air increased from 1 for vapor-phase congeners to 4 for fully particulate-bound congeners, indicating a personal cloud effect. Bedroom and main living area air samples were moderately correlated for non-209 BDEs (r = 0.45, p = 0.045) and BDE 209 (r = 0.58, p = 0.008). Use of personal air concentrations increased estimates of inhalation exposure over those previously reported. Inhalation may account for up to 22% of the total BDE 209 exposure in U.S. adults.
我们使用个人空气采样器，对大波士顿地区（马萨诸塞州）的20名居民室内空气中多溴二苯醚（PBDEs）的暴露情况进行了测量。同时从每位参与者家中的两个房间采集了区域空气样本。非209号多溴二苯醚的个人空气总浓度（颗粒物 + 蒸汽）为469 pg/m³，209号多溴二苯醚为174 pg/m³，显著高于卧室和主要起居室内的浓度（p = 0.01）。个人空气与室内空气的比例，从气相同系物的1增加到完全颗粒物结合同系物的4，表明存在个人云效应。对于非209号多溴二苯醚（r = 0.45，p = 0.045）和209号多溴二苯醚（r = 0.58，p = 0.008），卧室和主要起居区域的空气样本具有中等程度的相关性。与之前报告的相比，使用个人空气浓度增加了吸入暴露的估计值。在美国成年人中，吸入可能占209号多溴二苯醚总暴露量的22%。
