Polyurethane foam (PUF) disk passive air samples, deployed during 2014 in the Global Atmospheric Passive Sampling (GAPS) Network, were analyzed for a range of flame retardants (FRs) including polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD), brominated and chlorinated novel FRs, and organophosphate esters (OPEs). Mean concentrations of PBDEs and novel FRs at the 48 sites monitored ranged from 0.097 to 93 pg/m3 for Σ14PBDEs and from below detection limits to 126 pg/m3 for Σ15novel FRs. For PBDEs, the detected concentrations were similar to those previously reported from samples collected in 2005 at GAPS sites, suggesting global background atmospheric concentrations of PBDEs have not declined since regulatory measures were implemented. OPEs were detected at every GAPS site, with Σ18OPEs ranging from 69 to 7770 pg/m3. OPE concentrations were at least an order of magnitude higher than the PBDEs. This study presents the first data on global distributions of OPEs in the atmosphere, obtained from a single passive sampling monitoring network. Challenges that can arise in passive air sampling campaigns are also highlighted and addressed with suggested recommendations for future campaigns.

溴和氯化阻燃剂和有机磷酸酯的全球大气浓度
分析了2014年在全球大气被动采样（GAPS）网络中部署的聚氨酯泡沫（PUF）盘式被动空气样品的一系列阻燃剂（FR），包括多溴联苯醚（PBDE），六溴环十二烷（HBCD），溴化和氯化的新型阻燃剂和有机磷酸酯（OPE）。在48位点的多溴二苯醚和新颖FR的平均浓度监测从0.097不等至93皮克/米3为Σ 14多溴二苯醚和从低于检测限至126微克/米3为Σ 15新颖的帧中继。对于多溴二苯醚，其检测到的浓度与先前在2005年GAPS站点收集的样品中报告的浓度相似，这表明自实施监管措施以来，多溴二苯醚的全球本底大气浓度并未下降。在每个站点GAPS进行检测的OPE，用Σ 18的OPE范围从69至7770微克/米3。OPE浓度至少比PBDE高出一个数量级。这项研究提出了从单个被动采样监测网络获得的关于大气中OPE的全球分布的第一批数据。被动空气采样运动中可能出现的挑战也得到了强调，并针对未来运动提出了建议。
