摘要
食品中的农药残留检测长期以来一直是一项艰巨的挑战,其杂质干扰多,残留含量低,传统的提取方法常常因为无法将杂质分离而影响检测结果。由于食品中杂质种类众多,农药的种类繁多且理化性质各异,新型农药日益涌现,所以对样品的前处理提出了更高的要求。近年来,QuEChERS(Quick,Easy,Cheap,Effective,Rugged and Safe)作为一种新型的提取方法,由于具有快速、简单、廉价、有效、可靠、安全的特点,成为国内外广泛采用的样品前处理新技术,在多种农药、医药、兽药的气相或液相色谱分析中已经得到广泛应用。本文就国内外对QuEChERS法在各类食品以及其他动植物性农产品的农药残留检测中的应用和方法的改进进行了综述,并对QuEChERS法在今后农药残留检测的应用前景以及发展方向进行了展望。
Detection of pesticide residues in food has been a daunting challenge for its high impurities disturbances, low residual content, and multitudinous inseparable impurities using traditional extraction methods. The requirements of sample pre-treatment has been raised due to diverse food contaminants, a wide variety of pesticides and its physicochemical properties and growing emergence of new pesticides. In recent years, QuEChERS(quick, easy, cheap, effective, rugged and safe ), a novel extraction method, has become a widely used new sample pretreat- ment technology at domestic and abroad for its quick, easy, cheap, effective, rugged and safe features. QuEChERS method has been widely used in determining pesticides, pharmaceuticals, and veterinaries using gas or liquid chromatographic method. The article made a summary about the application of pesticide residue detection and method improvement of QuEChERS in various types of food and other animal/plant- agricultural products, and then the prospects of QuEChERS method for pesticide residues detection were proposed.
