Abstract

Per- and polyfluoroalkyl substances (PFAS) are an emerging class of organic compounds that are widely used in industrial production and therefore can be found in the environment. Dietary intake is the main route of human exposure to PFAS, especially in animal-derived foods. In this study, 25 PFAS compounds were determined in 234 animal by-products sold in Lanzhou City, China, by LC-MS/MS. In total 22 PFAS compounds were detected, among which PFBA and PFOS were detected most frequently, with average levels of 2.1 μg/kg and 1.8 μg/kg, respectively. The average level of total PFAS was 0.65 μg/kg, among which the contamination of liver was relatively high. Health risk assessment indicated that local animal by-products did not pose a significant risk to the health of the population, but attention needs to be paid to the health risks for children.

兰州动物副产品中PFAS及其健康风险评估

全氟和多氟烷基物质（PFAS）是一类新兴的有机化合物，广泛用于工业生产，因此可以在环境中找到。饮食摄入是人类接触PFAS的主要途径，尤其是动物源性食物。采用液相色谱-质谱联用技术（LC-MS/MS）对兰州市234种动物副产品中25种PFAS化合物进行了检测。共检测到22种PFAS化合物，其中PFBA和PFOS检测频率最高，平均含量分别为2.1 μg/kg和1.8 μg/kg。总PFAS平均含量为0.65 μg/kg，其中肝脏污染程度较高。健康风险评估表明，当地动物副产品不会对人口健康构成重大风险，但需要注意对儿童的健康风险。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
