Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous compounds released in the environment by different sources. The aim of the present work was to validate a solid-phase extraction (SPE) and a rapid ultra-high performance liquid chromatographic (UHPLC) method for the analysis of PAHs in a passive environmental sampler, namely a Dacron® (the commercial name of a synthetic fiber based on polyethylene terephthalate) textile. The elution temperature was optimized to improve the resolution of early-eluted compounds, namely acenaphthene (Ac) and fluorene (F). The UHPLC method lasts about 10 min and showed good linearity for all the 16 PAHs considered, with regression coefficients over 0.99. Recoveries, limits of detection (LODs), and limits of quantification (LOQs) of the SPE method were well within the performance criteria fixed by the Regulation n. 836/2011, namely 0.3 and 0.9 μg/kg, respectively.
多环芳烃（PAHs）是由不同来源释放到环境中的普遍存在的化合物。本工作的目的是验证固相萃取（SPE）和快速超高效液相色谱（UHPLC）法在被动环境采样器（即 Dacron®（一种基于聚对苯二甲酸乙二醇酯的合成纤维的商品名）纺织品）中分析 PAHs 的适用性。优化了洗脱温度以改善早期洗脱化合物（即苊（Ac）和芴（F））的分辨率。UHPLC 方法大约需要 10 分钟，对所有考虑的 16 种 PAHs 均表现出良好的线性，相关系数均大于 0.99。SPE 方法的回收率、检出限（LODs）和定量限（LOQs）均在法规 n. 836/2011 规定的性能标准范围内，分别为 0.3 和 0.9 μg/kg。
