背景尽管人造草坪在全球范围内广泛使用，但评估草坪组成部分中存在潜在有害化学物质的研究却很少。这项试点研究旨在评估一种适用的提取分析方法识别和定量FTOH的能力，FTOH是一类全氟烷基和多氟烷基物质（PFAS），方法采用甲醇：甲基叔丁基醚（80：20）提取人造草坪纤维和橡胶填充料中的FTOHs，甲醇复溶后，用气相色谱-质谱联用仪（GC-MS）在离子扫描模式（SIM）下进行分析。2在人造草坪纤维和橡胶屑填充物样品中检测到FTOH，浓度分别为1.0和0.71 ng/μL。这转化为300 ng 8：2 FTOH/g人造草皮纤维和110 ng 8：2 FTOH/g废橡胶粉。相比之下，4：2 FTOH和6：2 FTOH没有被发现是存在于可检测的levels.ConclusionOur提取方法与随后的GC-MS分析证明是有用的，在检测FTOH在人造草坪场样品。8：2 FTOH可能存在于人造草皮纤维和碎橡胶填充物中。这项试点调查支持需要进一步研究这类PFAS在人造草坪领域的组成部分。
BackgroundDespite widespread global use of artificial turf fields, there is a paucity of research assessing the presence of potentially harmful chemicals within the field components.ObjectiveThis pilot study aimed to assess the capacity of an adapted extraction-analysis method to identify and quantitate FTOHs, a class of perfluoroalkyl and polyfluoroalkyl substances (PFAS), in artificial turf fiber and crumb rubber infill samples.MethodsFTOHs in artificial turf fibers and crumb rubber infill were extracted using 80:20 methanol:methyltert-butyl ether, reconstituted in methanol, and analyzed by gas chromatography-mass spectroscopy (GC-MS) operated in scanning ion mode (SIM).Results8:2 FTOH was detected in artificial turf fiber and crumb rubber infill samples at concentrations of 1.0 and 0.71 ng/μL, respectively. This translates to 300ng 8:2 FTOH/g artificial turf fiber and 110ng 8:2 FTOH/g crumb rubber. By contrast, 4:2 FTOH and 6:2 FTOH were not found to be present in detectable levels.ConclusionOur extraction method with subsequent GC-MS analysis proved useful in detecting FTOHs in artificial turf field samples. 8:2 FTOH may be present in artificial turf fibers and crumb rubber infill. This pilot investigation supports the need for further research into the presence of this class of PFAS in artificial turf field components.
