全氟化合物（PFCs）已被确定在21个选定的食品和饮料，如肉类，鱼类，面包，蔬菜，牛奶，饮用水和茶从挪威标记的样本。在样品中检测到多达12种不同的PFC。发现全氟辛酸和全氟辛烷磺酸的浓度与世界范围内其他研究中观察到的浓度相似或更低。观察到动物源样本和非动物源样本中全氟辛酸和全氟辛烷磺酸的相对比例存在差异，这支持了全氟辛烷磺酸在动物体内的生物累积潜力高于全氟辛酸的结论。根据这21项测量结果和挪威一般人口的消费数据，经粗略估计，全氟化学品的总膳食摄入量约为100纳克·日（-1）。全氟辛酸和全氟辛烷磺酸约占总摄入量的50%。在按性别和年龄组划分人口时，估计摄入量随着年龄的增长而下降，男性高于女性。本研究中全氟辛烷磺酸和全氟辛酸的估计摄入量低于西班牙、德国、联合王国、加拿大和日本研究报告的摄入量。这项研究表明，通过改进测定食物样品中PFC的分析方法，可以检测到广泛的化合物，这在评估膳食暴露时很重要。(C)2010爱思唯尔有限公司版权所有。
Perfluorinated compounds (PFCs) have been determined in 21 samples of selected food and beverages such as meat, fish, bread, vegetables, milk, drinking water and tea from the Norwegian marked. Up to 12 different PFCs were detected in the samples. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) were found in concentrations similar to or lower than what has been observed in other studies world-wide. Differences in the relative proportion of PFOA and PFOS between samples of animal origin and samples of non-animal origin were observed and support findings that PFOS has a higher bio-accumulation potential in animals than PFOA. Based on these 21 measurements and consumption data for the general Norwegian population, a rough estimate of the total dietary intake of PFCs was found to be around 100 ng d(-1). PFOA and PFOS contributed to about 50% of the total intake. When dividing the population in gender and age groups, estimated intakes were decreasing with increasing age and were higher in males than females. The estimated intakes of PFOS and PFOA in the present study are lower than what has been reported in studies from Spain, Germany, United Kingdom, Canada and Japan. This study illustrates that by improving the analytical methods for determination of PFC in food samples, a broad range of compounds can be detected, which is important when assessing dietary exposure.
