摘要:

三嗪类除草剂会通过干扰内分泌系统的正常功能影响人类健康,很多国家已将部分此类化合物列入内分泌干扰剂化合物名单。作者从样品提取和仪器检测技术的发展趋势方面综述了环境和食品样品中三嗪类除草剂及其代谢产物的检测方法。在样品提取方面,液液萃取、固相萃取和固相微萃取技术简便且具有较高回收率,广泛应用于三嗪类除草剂的提取。另外,由于分子印迹、凝胶渗透色谱和加速溶剂萃取技术可以提高方法选择性和降低样品基质干扰,因而也越来越多地应用于三嗪类除草剂的提取工作;在检测技术方面,气相色谱和液相色谱法应用最为广泛。此外,由于色谱质谱联用技术可以大大降低方法检测限并能提高阳性样品的定性准确度,符合高通量和痕量检测的发展趋势,因此气相色谱/液相色谱串联质谱技术也广泛应用于三嗪类除草剂残留的定量和定性检测。

Abstract:

Triazine herbicides and their metabolites may be dangerous for human health because they are suspected to cause interruption of hormone functions.Some of these compounds have been listed as potential environmental endocrine disruptors by some countries.Analysis methods for detecting triazine herbicides and their metabolites residues in environmental and food samples,including sample extraction and instrumental determination,were reviewed here.Liquid-liquid extraction,solid phase extraction and solid phase micro-extraction have been widely used in the pretreatment of triazine herbicide and their metabolites residues due to its easy operation and high recovery over other techniques.In addition,due to the high selectivity and low matrix effect,the technique of molecular imprinting,gel permeation chromatography and accelerated solvent extraction have also been widely applied in the pretreatment of triazine herbicide and their metabolites residues.By far,gas chromatography and liquid chromatography are commonly-used analytical methods for the measure of triazine herbicide and their metabolites residues.Additionally,chromatography coupled mass spectrometry plays more and more important roles in the analysis of triazine herbicides and their metabolites residues because of its lower detection limit and higher selectivity.

Key words: triazine herbicides; metabolites residues; food; environment
