摘要 建立了4种常见食品接触材料(爆米花桶、烧烤油纸、汉堡纸袋、蛋挞锡纸)中7种全氟有机物(PFCs)残留的固相萃取-液相色谱-串联质谱(SPE-LC-MS/MS)分析方法。结果表明:市售4种食品接触材料中均存在一定程度的PFCs污染,其中爆米花桶中共检出4种PFCs,分别为全氟己酸、全氟庚酸、全氟辛酸和全氟壬酸,其平均含量分别为15.811 4、0.469 0、0.222 5和0.036 3μg/kg;烧烤油纸中共检出1种PFCs,为全氟己酸,平均含量为1.334 4μg/kg;汉堡纸袋中共检出2种PFCs,为全氟己酸和全氟庚酸,其平均含量分别为0.163 9和0.4599μg/kg;3批次的蛋挞锡纸中PFCs的污染程度不均:批次1和批次2共检出1种PFCs,为全氟己酸,其平均含量分别为1.461 0和0.177 0μg/kg;批次3中共检出6种PFCs,分别为全氟己酸、全氟庚酸、全氟壬酸、全氟十二烷酸、全氟十四烷酸和全氟辛烷磺酸盐,其平均含量分别为1.68、3.15、0.68、0.74、0.64、0.07μg/kg。通过阴性样品添加实验表明:方法的检出限为0.03~0.52μg/kg(S/N=3);平均回收率为88%~110%;相对标准偏差为1.7%~5.0%(n=6)。该方法前处理简单,回收率高,精密度好,适用于各类市售食品接触材料中PFCs的定量检测。

Abstract: A method was established for the determination of 7 perfluorinated compounds(PFCS) in four kinds of food wrapping materials(popcorn bucket,barbecue oiled papers,hamburger bags and egg tart tinfoil) by solid phase extraction coupled with liquid chromatography-tandem mass spectrometry(SPE-LC-MS /MS).The results showed that four kinds of PFCs including Perfluorohexanoic acid(PFHxA),perfluoroheptanoic acid(PFHpA),perfluorooctanoate acid(PFOA) and perfluorononanoic acid(PFNA) were detected in popcorn bucket and their average concentrations were 15.8114,0.4690,0.2225 and 0.0363 μg /kg,respectively;PFHxA was detected in barbecue oiled papers,and the average concentrations was 1.3344 μg /kg;PFHxA and PFHpA were detected in hamburger bags,and their average concentrations were 0.1639 and 0.4599 μg /kg;there was a different pollution degree between 3batches of egg tart tinfoil.PFHxA was detected in both batch 1 and 2,the average concentrations were 1.461 and0.1770 μg /kg,respectively;however six kinds were detected in bach 3 including perfluorochemicals including perfluorohexanoic acid,perfluoroheptanoic acid,perfluorooctanoate acid,perfluorododecanoic acid(PFDoA),perfluorotetradecanoic acid(PFTA) and perfluorooctane sulphonate(PFOS),and the average concentrations were 1.68,3.15,0.68,0.74,0.64 and 0.07 μg /kg,respectively.The limits of detection for the method(LODS),average recoveries and RSD for repeated measurements(n = 6) were 0.03 ~ 0.52 μg /kg,88% ~ 110% and 1.7% ~ 5.0%,respectively.The method was simple,accurate and sensitive.It was suitable for the determination and confirmation of PFCs in different kinds of food wrapping materials.
