Per- and polyfluoroalkylated substances (PFAS) are a large group of toxic compounds which have been widely used in industrial and consumer applications, from where they can migrate into the environment. They can pose a risk to human health because they have been associated with several diseases. To obtain more information on the risk of PFAS in fast food packaging materials, several PFAS (perfluorocarboxylic acids or PFCAs (n = 16), perfluorosulfonic acids or PFSAs (n = 14), and a miscellaneous group constituted by sulfonamides (n = 5) and fluorotelomer phosphate esters or PAPs (n = 5)) were quantified in food contact materials (FCMs) from fast-food restaurants in France. Perfluorohexanoic acid (PFHxA), 6:2 fluorotelomer sulfonic acid (6:2 FTS) and 6:2/6:2 fluorotelomer phosphate diester (6:2/6:2 diPAP) were detected in all samples. PFCAs with shorter chain lengths (C-C) showed the highest concentrations compared to median (C-C) and longer chain length PFCAs (C-C). However, they had lower detection frequencies (DFs) (except for PFHxA, DF = 100%) with values of 36 and 34% for C and C PFCAs, respectively. The DF of longer chain length PFCAs was higher, especially those of the median chain length PFCAs (C-C, with DF = 79-98%). Analytes from the PFSA group with high DFs (70-98%) were perfluorobutane sulfonic acid (PFBS), perfluorohexane sulfonic acid (PFHxS), perfluorooctane sulfonic acid (PFOS, linear and branched) and 10:2 fluorotelomer sulfonic acid (10:2 FTS), with concentrations similar to some analytes from the PFCA group. 4:2 Fluorotelomer phosphate monoester (4:2 mPAP), 8:2 fluorotelomer phosphate monoester (8:2 mPAP) and 8:2/8:2 fluorotelomer phosphate diester (8:2/8:2 diPAP) were found with the highest concentrations (<0.006-42.7 ng g, <0.001-2.7 ng g and <0.001-287 ng g, respectively) and the highest DFs (ranged 68-94%). Some correlations between analytes were found, indicating similar degradation routes or a common origin.
全氟和多氟烷基物质（PFAS）是一大类有毒化合物，已广泛应用于工业和消费应用领域，从这些领域它们可以迁移到环境中。它们可能对人类健康构成威胁，因为它们与几种疾病有关。为了获得更多关于快餐包装材料中 PFAS 的风险信息，在法国的快餐店食品接触材料（FCM）中定量了几种 PFAS（全氟羧酸或 PFCAs（n=16）、全氟磺酸或 PFSAs（n=14）以及由磺酰胺（n=5）和氟端基磷酸酯或 PAPs（n=5）组成的杂项组）。在所有样品中均检测到全氟己酸（PFHxA）、6:2 氟代硫酸（6:2 FTS）和 6:2/6:2 氟代磷酸二酯（6:2/6:2 diPAP）。与中链（C-C）和长链 PFCAs（C-C）相比，短链 PFCAs（C-C）的浓度最高。然而，它们的检测频率（DF）较低（除 PFHxA 外，DF=100%），C 和 C PFCAs 的 DF 分别为 36%和 34%。长链 PFCAs 的 DF 更高，特别是中链 PFCAs（C-C）的 DF 为 79-98%。具有高 DF（70-98%）的 PFSA 组的分析物为全氟丁烷磺酸（PFBS）、全氟己烷磺酸（PFHxS）、全氟辛烷磺酸（线性和支链）和 10:2 氟代硫酸（10:2 FTS），其浓度与某些 PFCAs 组的分析物相似。发现 4:2 氟代磷酸单酯（4:2 mPAP）、8:2 氟代磷酸单酯（8:2 mPAP）和 8:2/8:2 氟代磷酸二酯（8:2/8:2 diPAP）具有最高浓度（<0.006-42.7ng/g、<0.001-2.7ng/g 和 <0.001-287ng/g）和最高 DF（68-94%）。发现一些分析物之间存在相关性，表明它们具有相似的降解途径或共同的来源。
