Firefighting is classified as a 2B-possibly carcinogenic profession by the International Agency for Research on Cancer (IARC). Firefighters are exposed to a host of toxic fireground contaminants such as phenols, phthalates, and polycyclic aromatic hydrocarbons (PAHs), many of which are potentially carcinogenic. Studies show that the exposure to contaminated firefighter gear postfire poses a health risk to the firefighters. This study focused on the issue of contaminants being present on the gear and developing a thermal extraction method to perform the assessment. A headspace sampler (HS) connected to a gas chromatography–mass spectrometry (GC–MS) system was used to thermally extract known fireground contaminants and understand the effect of equilibration time and temperature on the thermal extraction efficiencies. The outer shell fabric samples (PBI/Kevlar blend) were spiked with known amounts of fireground chemicals, heated at various temperatures (36, 50, 100, and 200 °C), and analyzed using the developed method to calculate extraction efficiencies. This study is one of the first to utilize the all-in-one HS–GC–MS instrument to analyze the thermal extraction of a variety of fireground contaminants relative to different temperatures from firefighter gear materials. Based on the conditions evaluated, the results indicate that the 200 °C condition allowed for the maximum thermal extraction of contaminants from the outer shell material. The data collected from this study pave a way of creating a new method for the analysis of volatile and semivolatile contaminants from field-contaminated firefighter turnout material using HS–GC–MS.

开发顶空采样-气相色谱-质谱法来分析消防员道岔材料上的火场污染物

消防被国际癌症研究机构 (IARC) 列为 2B 级可能致癌职业。消防员会接触大量有毒的火场污染物，例如苯酚、邻苯二甲酸盐和多环芳烃 (PAH)，其中许多污染物具有潜在的致癌性。研究表明，火灾后接触受污染的消防员装备会对消防员的健康构成风险。这项研究的重点是齿轮上存在污染物的问题，并开发了一种热提取方法来进行评估。连接到气相色谱-质谱 (GC-MS) 系统的顶空进样器 (HS) 用于热提取已知的火场污染物，并了解平衡时间和温度对热提取效率的影响。外壳织物样品（PBI/Kevlar 混合物）中加入了已知量的火场化学品，在不同温度（36、50、100 和 200 °C）下加热，并使用开发的方法进行分析以计算提取效率。这项研究是第一个利用一体化 HS-GC-MS 仪器来分析消防员装备材料中各种火场污染物相对于不同温度的热提取的研究之一。根据评估的条件，结果表明 200 °C 条件可以最大程度地从外壳材料中热提取污染物。本研究收集的数据为创建一种使用 HS-GC-MS 分析现场污染的消防员消防材料中的挥发性和半挥发性污染物的新方法铺平了道路。
