Research Progress on Contamination and Determination Methods of Perfluorinated Compounds in Food
-
摘要: 全氟化合物以其优良的稳定性及表面活性作为加工助剂已被应用于多个领域,但它是一类多脏器毒性的环境污染物,具有持久性、生物积累性、难降解性等特点。本文综述了全氟辛酸和全氟辛烷磺酸等全氟化合物的危害、各国对其使用的限制和规定、各类食品中全氟化合物的污染情况和含量水平的差异,重点比较了不同测定全氟化合物方法的优劣,阐述了今后检测技术的发展方向,为我国开展食品中全氟化合物的风险评估及研究提供参考。Abstract: Due to the excellent stability and surfactivity of perfluorinated compounds,they have been used in many fields. However,they are a kind of environmental pollutants with multiple organ toxicity,which have the characteristics of persistence,bioaccumulation and hard degradation. The article mainly summarizes the harm of perfluorinated compounds such as perfluorooctanoic acid and perfluorooctane sulfonate,the domestic and international restrictions and regulations on them. The contamination levels of perfluorinated compounds in different kinds of food were also reviewed. The recent research progress on determination technology of perfluorinated compounds in food was introduced. The advantages and disadvantages of different determination methods are compared emphatically,and the development direction of detection technology in the future is expounded. The article would provide references for the risk assessment and studies on perfluorinated compounds in food.
