饲料中新型持久性有机污染物分析方法与污染特征研究进展

饲料是养殖动物的主要食物来源,饲料中的持久性有机污染物(POPs)能够在养殖动物体内蓄积,从而影响动物源性食品安全,对人体健康构成潜在的危害.目前有关饲料中二口恶]英类等传统POPs的研究已较为深入,而饲料中新型POPs的污染也逐渐引起人们的关注.本文综述了现有文献关于饲料中多溴二苯醚(PBDEs)、六溴环十二烷(HBCD)、全氟化合物(PFASs)、多氯萘(PCNs)和短链氯化石蜡(SCCPs)的分析方法、污染水平、同类物分布特征及污染来源分析等方面的研究,提出了饲料中新型POPs研究亟待解决的问题.

Progress on analysis methods and characteristics of emerging persistent organic pollutants in animal feed

Animal feed is the main food source for cultured animals. Persistent organic pollutants(POPs) in feed and feed additives could accumulate in farmed animals and tend to cause potential adverse effects in humans through the food chain. In the past decades, a large number of researches have focused on the 12 initial POPs under the Stockholm Convention, e.g. dioxins, in animal feed. In recent few years, emerging POPs present in animal feed have attracted increasing attention. In this paper, analysis methods, contamination levels, congener profiles and polluted sources of emerging POPs, including polybrominated diphenyl ethers(PBDEs), hexabromocyclododecane(HBCD), perfluoroalkyl substances(PFASs), polychlorinated naphthalenes(PCNs), and short-chain chlorinated paraffins(SCCPs) in animal feed were summarized based on the published literatures. Emerging issues related to emerging POPs in animal feed need to be solved.
