我们测量了韩国66种397种食品中PFAA的浓度，并确定了人类日常饮食中PFAA的摄入量以及每种食物对摄入量的贡献。66种不同食品中的PFAA含量从低于检测限到48.3 ng/g不等。鱼、贝类和加工食品中的PFAA主要是全氟辛烷磺酸(PFOS)和长链全氟羧酸(PFCAs)，而乳制品和饮料中主要是全氟辛酸(PFOA)和短链PFCAs。在各种情况下估计的韩国成年人膳食摄入量范围，全氟辛烷磺酸和全氟辛酸分别为0.60-3.03和0.17-1.68 ng kg(-1)bw d(-1)，低于欧洲食品安全局建议的每日总摄入量限值(全氟辛烷磺酸：150 ng kg(-1)bw d(-1)；全氟辛烷磺酸：1500 ng kg(-1)bw d(-1))。PFAAs膳食暴露的主要贡献者随受试者年龄和PFAA的不同而不同。例如，鱼是全氟辛烷磺酸的主要贡献者，但乳制品是全氟辛烷磺酸的主要贡献者。然而，自来水是饮用水(而不是瓶装水)的主要来源，而自来水是全氟辛烷磺酸摄入量的主要来源。(C)2014爱思唯尔B.V.保留所有权利。
We measured concentrations of PFAAs in 397 foods, of 66 types, in Korea, and determined the daily human dietary PFAAs intake and the contribution of each foodstuff to that intake. The PFAAs concentration in the 66 different food types ranged from below the detection limit to 48.3 ng/g. Perfluorooctane sulfonate (PFOS) and long-chain perfluorocarboxylic acids (PFCAs) were the dominant PFAAs in fish, shellfish, and processed foods, while perfluorooctanoic acid (PFOA) and short-chain PFCAs dominated dairy foodstuffs and beverages. The Korean adult dietary intake ranges, estimated for a range of scenarios, were 0.60-3.03 and 0.17-1.68 ng kg(-1) bw d(-1) for PFOS and PFOA, respectively, which were lower than the total daily intake limits suggested by European Food Safety Authority (PFOS: 150 ng kg(-1) bw d(-1); PFOA: 1500 ng kg(-1) bw d(-1)). The major contributors to PFAAs dietary exposure varied with subject age and PFAAs. For example, fish was a major contributor of PFOS but dairy foods were major contributors of PFOA. However, tap water was a major contributor to PFOA intake when it was the main source of drinking water (rather than bottled water). (C) 2014 Elsevier B.V. All rights reserved.
