随着多溴二苯醚 (PBDE) 的逐步淘汰，有机磷阻燃剂 (PFR) 越来越多地在许多产品中用作替代阻燃剂。关于消费品中存在两种替代 PFR：间苯二酚双（二苯基磷酸酯）（PBDPP 或 RDP）和双酚 A 双（二苯基磷酸酯）（BPA-BDPP 或 BDP）的数据仍然很少或不存在。在这项研究中，我们提出了一种简单的提取方法，并通过液相色谱-大气压化学电离 (APCI) 与高分辨率飞行时间质谱 (TOF) 结合对塑料消费品进行分析。检测限足够低，可用于塑料或电子样品中的痕量定量（PBDPP 和 BPA-BDPP 分别为 0.001% 和 0.002% w/w）。在分析这些 PFR 时，APCI 源比常用的 ESI 源提供了更好的灵敏度和基质效应。 2012 年购买的 12 种产品中有 7 种同时检测到了 PBDPP 和 BPA-BDPP（PBDPP 为 0.002-03% w/w，BPA-BDPP 为 0.02-0.18% w/w），而 2006 年之前购买的 13 种产品中仅检测到了 4 种 PBDPP（0.005-7.8% w/w）。在新购买的产品中，PBDPP、BPA-BDPP 和磷酸三苯酯 (TPHP) 是最常检测到的 PFR。这些结果支持了我们研究小组最近关于电子设备收集的室内灰尘中 PBDPP 和 BPA-BDPP 浓度高达 0.5-1 mg g(-1) 的研究结果，并强调了对这两种新型 PFR 进行进一步研究的必要性。 (C) 2014 Elsevier Ltd. 保留所有权利。
Following the phase-out of polybrominated diphenyl ethers (PBDEs), organophosphorus flame retardants (PFRs) are increasingly used as alternative flame retardants in many products. Data on the presence of two alternative PFRs in consumer products, resorcinol bis (diphenylphosphate) (PBDPP or RDP) and bisphenol A bis (diphenylphosphate) (BPA-BDPP or BDP) is still scarce or non-existing. In this study we propose a simple extraction method and analysis by liquid chromatography-atmospheric pressure chemical ionization (APCI) coupled to a high resolution time-of-flight mass spectrometry (TOF) for plastic consumer products. Detection limits were low enough for trace quantitation in plastic or electronic samples (0.001% and 0.002% w/w for PBDPP and BPA-BDPP, respectively). The APCI source provided better sensitivity and matrix effects than the commonly used ESI source for the analysis of these PFRs. Both PBDPP and BPA-BDPP were detected in 7 of the 12 products purchased in 2012 (at 0.002-03% w/w for PBDPP and 0.02-0.18% w/w for BPA-BDPP) while only PBDPP was found in 4 of the 13 products purchased before 2006 (0.005-7.8% w/w). In newly purchased products, PBDPP, BPA-BDPP and triphenyl phosphate (TPHP) were the most frequently detected PFRs. These results support the recent findings of our research group about high concentration levels of PBDPP and BPA-BDPP up to 0.5-1 mg g(-1) in house dust collected on electronic equipment and highlights the need for further research on these two novel PFRs.
