液相色谱-质谱联用技术在水产品兽药残留检测中的应用

Application of Liquid Chromatography-Mass Spectrometry in Detection of Veterinary Drug Residues in Aquatic Products

水产品是人们日常生活中常见的食品之一,为治疗鱼虾各类疫病,养殖人员在水产品饲养中通常会使用大量兽药,这些兽药一部分会随着水产品排泄排出体外,另一部分则会长期存留在水产品体内,长期摄入兽药残留超标的水产品会对人体的健康造成很大影响。目前,水产品兽药残留检测方法较多,而液相色谱-质谱联用技术(Liquid Chromatography-Mass Spectrometry,LC-MS)凭借检测时间短、灵敏度高、检测成本低等优势,已成为现阶段水产品兽药残留检测的主要方法之一。因此,本文对LC-MS在水产品兽药残留检测中的应用展开探究,分析LC-MS的特点,探究其在硝基呋喃类、喹诺酮类等兽药检测中的应用,以期为水产品兽药检测提供一定参考。

Aquatic products are one of the common foods in people’s daily life.In order to treat various diseases of fish and shrimp,breeders usually use a large number of veterinary drugs in aquatic products.Some of these veterinary drugs will be excreted with aquatic products,and the other part will remain in aquatic products for a long time.Long-term intake of aquatic products with excessive veterinary drug residues will have a great impact on human health.At present,there are many methods for the detection of veterinary drug residues in aquatic products.liquid chromatography-mass spectrometry(LC-MS)has become one of the main methods for the detection of veterinary drug residues in aquatic products due to its advantages of short detection time,high sensitivity and low detection cost.Therefore,this paper explores the application of LC-MS in the detection of veterinary drug residues in aquatic products,analyzes the characteristics of LC-MS,and explores its application in the detection of veterinary drugs such as nitrofurans and quinolones,in order to provide a reference for the detection of veterinary drugs in aquatic products.
