ICP-MS法测定药食同源性食物中的重金属及有害元素
|
摘要
建立药食同源性食品中的重金属及有害元素的残留量测定方法,为相关品种的重金属及有害元素的测定、标准完善及风险评估提供依据。采用电感耦合等离子体质谱(ICP-MS)法测定药食同源性食品中铅、镉、砷、汞、铜的含量。结果表明,5种重金属及有害元素的线性关系良好相关系数均大于0.9953,回收率为82.25%～115.13%,重复性良好。参照《中国药典》枸杞、黄芪等药食同源性食物的重金属及有害元素限量标准,17种73批药食同源性食物五种重金属元素含量测定的合格率为98.90%,其中镉存在超标现象,合格率为94.52%。本文采用的ICP-MS法适用于药食同源食品中的多种元素同时测定。实验显示少数个别品种的个别元素污染严重,建议重视此方面的控制,完善相关检测方法和限量标准。
A method for the determination of heavy metals and harmful elements in medicine food homologous food was established,so as to provide for risk evaluation,standard improvement and quality supervision for the related food.The contents of lead,cadmium,arsenic,mercury and copper in medicine food homologous food were determined by inductively coupled plasma mass spectrometry( ICP-MS).The results showed that the linear relationship of five heavy metal elements was good( r >0.9953),the recovery rate ranged from 82.25% to 115.13%,and the repeatability was also good. The established method was applicable for determining the amount of heavy metals and harmful elements of medicine food homologous food. According to limits of heavy metals and harmful elements for medicine food homologous food such as leech in Chinese Pharmacopoeia,the qualified rate of heavy metals and harmful elements in 17 kinds of 73 batches of medicine food homologous food was 98.90%.Among them,the cadmium exceeded the standard,and the qualified rate was 94.52%.The ICP-MS method used in this paper was suitable for simultaneous determination of many elements in medicine food homologous food.The experiment showed that the contamination of individual elements in a few species was serious. It was recommended to take control of this aspect and improved relevant detection methods and limit standards.
