Per- and polyfluoroalkyl substances (PFASs) are highly persistent synthetic chemicals, some of which have been associated with cancer, developmental toxicity, immunotoxicity, and other health effects. PFASs in grease-resistant food packaging can leach into food and increase dietary exposure. We collected ~400 samples of food contact papers, paperboard containers, and beverage containers from fast food restaurants throughout the United States and measured total fluorine using particle-induced γ-ray emission (PIGE) spectroscopy. PIGE can rapidly and inexpensively measure total fluorine in solid-phase samples. We found that 46% of food contact papers and 20% of paperboard samples contained detectable fluorine (>16 nmol/cm2). Liquid chromatography/high-resolution mass spectrometry analysis of a subset of 20 samples found perfluorocarboxylates, perfluorosulfonates, and other known PFASs and/or unidentified polyfluorinated compounds (based on nontargeted analysis). The total peak area for PFASs was higher in 70% of samples (10 of 14) with a total fluorine level of >200 nmol/cm2 compared to six samples with a total fluorine level of <16 nmol/cm2. Samples with high total fluorine levels but low levels of measured PFASs may contain volatile PFASs, PFAS polymers, newer replacement PFASs, or other fluorinated compounds. The prevalence of fluorinated chemicals in fast food packaging demonstrates their potentially significant contribution to dietary PFAS exposure and environmental contamination during production and disposal.

美国快餐包装中的氟化物。

全氟烷基物质和多氟烷基物质(PFAS)是高度持久的合成化学品,其中一些与癌症,发育毒性,免疫毒性和其他健康影响有关。耐油脂食品包装中的PFAS可能渗入食品并增加饮食摄入量。我们从美国各地的快餐店收集了约400个食品接触纸,纸板容器和饮料容器的样品,并使用粒子诱导的γ射线发射(PIGE)光谱仪测量了总氟。PIGE可以快速,廉价地测量固相样品中的总氟。我们发现46%的食品接触纸和20%的纸板样品包含可检测到的氟(> 16 nmol / cm2)。液相色谱/高分辨率质谱法分析了20个样品的子集,发现了全氟羧酸盐,全氟磺酸盐和其他已知的PFAS和/或不确定的多氟化合物(基于非目标分析)。PFAS的总峰面积在70%的样品(14个样品中有10个)中总氟含量> 200 nmol / cm2时要比六个样品中的总氟含量<16 nmol / cm2高。总氟含量高但测得的PFAS含量低的样品可能包含挥发性PFAS,PFAS聚合物,更新的PFAS或其他氟化化合物。快餐包装中含氟化合物的流行表明,它们在生产和处置过程中对饮食中PFAS暴露和环境污染的潜在重要贡献。PFAS的总峰面积在70%的样品(14个样品中有10个)中总氟含量> 200 nmol / cm2时要比六个样品中的总氟含量<16 nmol / cm2高。总氟含量高但测得的PFAS含量低的样品可能包含挥发性PFAS,PFAS聚合物,更新的PFAS或其他氟化化合物。快餐食品包装中含氟化合物的流行表明,它们在生产和处置过程中对饮食中PFAS暴露和环境污染的潜在重要贡献。PFAS的总峰面积在70%的样品(14个样品中有10个)中总氟含量> 200 nmol / cm2时要比六个样品中的总氟含量<16 nmol / cm2高。总氟含量高但测得的PFAS含量低的样品可能包含挥发性PFAS,PFAS聚合物,更新的PFAS或其他氟化化合物。快餐食品包装中含氟化合物的流行表明,它们在生产和处置过程中对饮食中PFAS暴露和环境污染的潜在重要贡献。或其他氟化化合物。快餐包装中含氟化合物的流行表明,它们在生产和处置过程中对饮食中PFAS暴露和环境污染的潜在重要贡献。或其他氟化化合物。快餐包装中含氟化合物的流行表明,它们在生产和处置过程中对饮食中PFAS暴露和环境污染的潜在重要贡献。
