全氟烷基酸（PFAA）在动物性食品中的存在是世界性的，其在新疆的归宿和空间分布还不清楚。本研究采用离子对法结合HPLC-MS/MS对采自新疆南部5个主要城市的牛肉和牛肝中的13种全氟乙酸进行了分析（n = 70）。总体而言，全氟乙酸污染范围很广，超过50%的样品的浓度范围从低于检测限到6.118 ng/g。全氟辛烷磺酸、全氟辛酸和全氟十一烷酸是10种检测化合物中的主要PFAA，库尔勒市肝脏样品中的最大浓度分别为2.543、0.856和1.386 ng/g。在比较这五个城市时，库尔勒的样品中观察到最高水平和检出频率（肌肉，0.013纳克/克;肝脏，3.336纳克/克），其次是焉耆、阿克苏、喀什和和田。不同城市PFAAs的污染模式和分布特征与当地的经济和地理条件有关。此外，对全氟辛酸的膳食摄入量评估显示，来自库尔勒的样品对人体健康的影响最大，但总风险比为0.814 × 10 −3，远小于1，表明食用牛肉和肝脏对当地居民没有直接危害。
The presence of perfluoroalkyl acids (PFAAs) in animal foods is worldwide, and their fate and spatial distribution in Xinjiang are not well understood. In this study, beef muscle and liver collected from five major cities in southern Xinjiang were analyzed (n = 70) for 13 PFAAs using an ion-pairing method combined with HPLC-MS/MS. Overall, PFAA contamination was widespread, exceeding 50% of samples with concentrations ranged from below the limits of detection to 6.118 ng/g. Perfluorooctane sulfonate, perfluorooctanoic acid, and perfluoroundecanoic acid were the predominant PFAAs of ten detected compounds, with maximum concentrations in Korla liver samples of 2.543, 0.856, and 1.386 ng/g, respectively. When comparing the five cities, the highest levels and detection frequencies were observed in samples from Korla (muscle, 0.013 ng/g; liver, 3.336 ng/g), followed by Yanqi, Akesu, Kashgar, and Hotan. The different pollution patterns and distribution profiles of PFAAs among cities were significantly related to local economy and geographical conditions. In addition, the dietary intake assessments for PFAAs showed that samples originating from Korla had the greatest impact on human health, but the total hazard ratio was 0.814 × 10 −3 , which is far less than 1, indicating that consumption of beef muscle and liver poses no immediate harm to local residents.
