磺酰脲类除草剂毒性及多残留检测技术研究进展
磺酰脲类除草剂是一种高效、广谱、高选择性的除草剂, 主要用于防除阔叶杂草和禾本科杂草。磺酰脲类除草剂在现代农业生产中发挥了重要作用, 但其农药残留问题也给生态环境和农产品质量安全造成诸多负面影响。本文主要对磺酰脲类除草剂的毒性危害、限量标准、残留检测的前处理以及仪器分析方法进行综述。目前对于磺酰脲类除草剂残留的检测主要涉及到土壤和水, 其次还有粮谷、动物源性食品等多种基质, 国内对于此类除草剂残留检测常用的前处理方法为固相萃取法, C18为常见填料, 在仪器分析方面, 液相色谱-质谱联用法以其灵敏度高、能检测痕量水平的残留而成为此类除草剂分析的首选方法。同时, 国内外针对此类除草剂的残留检测, 已经由过去的单残留检测向多残留检测发展。
Sulfonylurea herbicides are highly effective, broad-spectrum, highly selective herbicides for controlling broadleaf weeds and gramineous weeds. Sulfonylurea herbicides play an important role in modern agricultural production, but their pesticide residues also have many negative effects on the ecological environment and safety of agricultural products. This paper mainly reviewed toxic hazards of sulfonylurea herbicides, limits of standards, pre-treatment of residual detection and instrumental analysis methods. At present, the detection of sulfonylurea herbicide residues mainly involve soil and water, as well as grain, animal-derived food and other matrixes. The domestic pre-treatment method commonly used for the detection of such herbicide residues is solid phase extraction method and C18 is the common filler. Liquid chromatography-mass spectrometry has become the preferred method for such herbicide analysis due to its high sensitivity and the ability that can detect trace levels of residues. At the same time, the residual detection of herbicides has been developed from single residue detection to multi-residue detection.
