食品中重金属检测方法研究进展

镉、铬、铅、砷和汞等重金属元素在人体内蓄积到一定浓度时,可危害中枢神经、血液及各器官,导致各种疾病,甚至癌症。食品安全直接关系人民健康,食品中重金属含量超标事件时有发生,对人们的身体健康有潜在的威胁,因此对于食品中重金属含量的检测十分必要。本文综述了常用的检测食品中重金属含量的方法,包括:原子荧光光谱法、X射线荧光光谱法、电感耦合等离子体-质谱法、电感耦合等离子体-原子发射光谱法、原子吸收光谱法等,简述其优缺点,并介绍各种检测方法检测食品中重金属含量的应用实例,以期对检测重金属的发展提供一定的参考价值,以更好地做好食品安全和维护人民健康,并且对重金属检测方法的发展作出展望。

Research progress on analysis technologies of heavy metals in foods

Cd, Cr, Pb, As, Hg and other heavy metal elements do great harm to human health. They can lead to variety of diseases, even cancer. The content of heavy metal in food often exceeds standards, and it is a threat to human health. Therefore, the detection of heavy metal content in food is necessary. This article provided an overview of commonly used detection method for heavy metal content in food, such as atomic fluorescence spectrometry, X-ray fluorescence spectrometer, inductive coupling plasma-mass spectrometry, inductive coupling plasma-atomic emission spectrometry and atomic fluorescence spectrometry, and their characteristics were introduced, outlining their strengths and weaknesses. Application examples about detection of heavy metals in food by these methods were introduced, so as to provide a reference for the detection of heavy metals in food. The development of detection methods for heavy metals was also prospected.
