食品中多溴二苯醚类化合物检测技术研究进展

Advances in the detection technology of polybrominated diphenyl ethers in food

多溴二苯醚(Polybrominated diphenyl ethers, PBDEs)是一类持久性有机污染物,因其具有高疏水性,普遍应用在日常产品的防火。另外由于具有潜在致癌性和抗降解性,已成为人类健康和环境的一大问题。在生物体内积累的多溴二苯醚会通过食物链富集于人体,从而对健康饮食和人体寿命构成一定威胁。本文综述了近年来常见多溴二苯醚的种类、提取方法、净化方法、检测技术以及多溴二苯醚的生物危害性;探讨了各项分析检测技术的现存劣势。目前国内有多溴二苯醚消费品检测标准,但无相关食品基质检测标准,因其基质的物质种类繁多等因素导致检测技术存在巨大挑战,文中也对后续的检测技术发展提出展望,以此为食品中多溴二苯醚检测技术发展和研究提供一定的支持。

Polybrominated diphenyl ethers(PBDEs) are a class of persistent organic pollutants. Because of their high hydrophobicity, PBDEs are widely used in the fire prevention of daily products. In addition, it has become a major problem of human health and environment because of its potential carcinogenicity and anti degradation. Polybrominated diphenyl ethers accumulated in organisms can be enriched in the human body through the food chain, thus posing a threat to healthy diet and human longevity. This paper reviewed the types of common PBDEs, extraction methods, decontamination methods, detection techniques, and the biohazard of PBDEs in recent years, and discussed the existing disadvantages of various analysis and detection technologies. At present, there are testing standards for polybrominated diphenyl ethers consumer products in China, but there is no relevant food matrix testing standard. Due to the wide variety of substances in the matrix, there are great challenges in the testing technology. The future development of detection technology was also prospected, so as to provide some support for the development and research of detection technology of polybrominated diphenyl ether in food.
