To study the contamination of perfluoroalkyl acids (PFAAs) in Chinese food and the risk of dietary exposure for the Chinese population, the data of 17 PFAAs covering 38 cities throughout China in 15 groups of foods were collected for meta-analysis from published and available research literature. Using food consumption and body weight parameters, estimated dietary intakes (EDIs) were calculated for evaluation using the Scenario-Based Risk Assessment (SceBRA) modelling. Among food groups, the highest ΣPFAAs concentrations and EDI contributions were both found in poultry (363 ng/g), fish and shrimp (313 ng/g), dark vegetables (309 ng/g), fruits (116 ng/g) and pork (25 ng/g). The EDI of adults in the high-exposure scenario was about twice that of the intermediate-exposure scenario, while the EDI of children was about twice that of adults' EDI in the intermediate-exposure scenario. In addition, the PFOS EDI for children under high exposure approached its tolerable daily intake (TDI). Therefore high dietary exposure to PFAAs is giving rise to an increased health risk, especially for children.
为研究中国食品中全氟烷基酸（PFAAs）的污染情况以及中国人群的膳食暴露风险，从已发表的和可得的研究文献中收集了覆盖中国38个城市15类食品中17种PFAAs的数据，进行荟萃分析。利用食物消费量和体重参数，采用基于情景的风险评估（SceBRA）模型计算估计膳食摄入量（EDIs）以进行评估。在各类食物中，家禽（363纳克/克）、鱼虾（313纳克/克）、深色蔬菜（309纳克/克）、水果（116纳克/克）和猪肉（25纳克/克）中的总PFAAs浓度和EDI贡献均最高。高暴露情景下成年人的EDI约为中等暴露情景下的两倍，而儿童的EDI约为中等暴露情景下成年人EDI的两倍。此外，高暴露下儿童的全氟辛烷磺酸EDI接近其每日可耐受摄入量（TDI）。因此，高膳食暴露于PFAAs会增加健康风险，尤其是对儿童而言。
