In this study, investigation was conducted into concentrations of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in Chinese farmed Trachinotus ovatus between 2014 and 2015 using a modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) and ultra fast liquid chromatography-tandem mass spectrometry (UFLC-MS/MS) method. The tissue distribution (muscle, skin, liver, kidney and gill) in Trachinotus ovatus was also assessed. The detection frequencies of PFOS and PFOA in fish were 92% and 3%, respectively, and the mean concentrations were 0.392 and 0.015 μg/kg wet weight. The analysis of PFOS distribution in different tissues in Trachinotus ovatus showed the following trend: skin> gill> kidney> liver> flesh. Results revealeded farmed Trachinotus ovatus in China to generally be contaminated with PFOS. Moreover, the average daily intake for Chinese urban residents calculated on the basis of pollution content was 0.268 ng/kg body weight/d (PFOS) and 0.014 ng/kg body weight /d (PFOA), respectively. Both hazard ratio values were less than 1, indicating that exposure levels of PFOS and PFOA through Trachinotus ovatus consumption may not lead to adverse health effects in the Chinese population.
本研究采用改良的QuEChERS（快速、简便、廉价、有效、耐用且安全）和超快速液相色谱-串联质谱法（UFLC-MS/MS），对2014年至2015年中国养殖卵形鲳鲹体内的全氟辛烷磺酸（PFOS）和全氟辛酸（PFOA）浓度进行了调查。同时还评估了卵形鲳鲹的组织分布（肌肉、皮肤、肝脏、肾脏和鳃）。鱼类中PFOS和PFOA的检出频率分别为92%和3%，平均浓度分别为0.392和0.015μg/kg湿重。卵形鲳鲹不同组织中PFOS分布分析显示如下趋势：皮肤＞鳃＞肾脏＞肝脏＞鱼肉。结果表明，中国养殖的卵形鲳鲹普遍受到PFOS污染。此外，根据污染含量计算的中国城市居民平均每日摄入量分别为0.268 ng/kg体重/天（PFOS）和0.014 ng/kg体重/天（PFOA）。两个危害比值均小于1，表明通过食用卵形鲳鲹摄入PFOS和PFOA的水平可能不会对中国人群造成健康不良影响。
