摘　　要：取代脲类除草剂是一类在世界范围内被广泛使用的除草剂,具有除草高效、经济等优点,能大幅提高劳动生产率,保障农业高产、稳产。但其化学性质稳定、降解速度慢、残留期长,对环境及人类具有潜在危害。因此,对该类除草剂的残留检测研究显得尤为重要。我们对取代脲类除草剂的前处理和检测方法及其进展进行综述,总结在水质、农作物及蔬菜、水果、海产品等不同基质中所采用提取方式的差异及优缺点。随着检测技术的发展,色谱与质谱的串联技术在取代脲类除草剂检测研究中应用越来越广。The sustituted urea herbicides,which have the advantages of high efficiency and low cost,are widely used in the world.They greatly improve labor productivity and crops yield. However,their chemical properties are stable,slow degradation speeds and long residual periods make potential harm to the environment and human beings. Therefore,it is very important to study the residue detection technology of sustituted urea herbicides. We summarize research progress on pretreatment and detection methods of sustituted urea herbicides,evaluate the differences,advantage and disadvantage of extraction methods used in different substrates such as water quality,crops,vegetables,fruits and seafood. With the development of detection technology,chromatography tandem mass spectrometry technology has been more and more widely used in the determination of sustituted urea herbicides.
