Abstract

ABSTRACT To study the contamination levels of perfluoroalkyl acids (PFAAs) in Chinese eggs and the effects of persistent organic pollutant (POP) amendments to the Stockholm Convention blacklist, 3200 eggs from 10 major producing areas were collected from June 2013 to May 2017. Seventeen PFAAs in eggs were analysed. Perfluorooctane sulphonic acid (PFOS), perfluoropentanoic acid (PFPeA) and perfluorooctanoic acid (PFOA) were the main PFAAs in eggs. Perfluoroalkyl carboxylic acids (PFCAs) and short-chain PFAAs levels in eggs decreased after the amendment was implemented in China (p < .05), but no significant difference was observed in PFOS. The average ΣPFAAs of eggs from 10 major producing areas was 0.23 ng/g (

全氟烷基在中国鸡蛋中的时空分布

为研究中国鸡蛋中全氟烷基酸(PFAAs)的污染水平以及《斯德哥尔摩公约》持久性有机污染物(POP)黑名单修正案的影响，研究人员于2013年6月至2017年5月收集了10个主要产区的3200个鸡蛋。分析了鸡蛋中的17种PFAAs。全氟辛烷磺酸(PFOS)、全氟戊酸(PFPeA)和全氟辛酸(PFOA)是鸡蛋中主要的PFAAs。修订后，中国鸡蛋中的全氟烷基羧酸(PFCAs)和短链PFAAs含量下降(p < 0.05)，但PFOS含量无显著差异。10个主要产区鸡蛋的平均ΣPFAAs值为0.23 ng/g (< LOD-5.4 ng/g)，其中湖南、湖北和河南的样本高于该阈值，表明需要对污染物管理实践进行更严格的评价和监管。全氟辛烷磺酸风险鸡蛋的检出率很低，未发现与食用相关的健康风险。

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.
