单体稳定同位素分析技术在有机污染物溯源中的应用研究进展

Research progress on the application of compound-specific isotope analysis in the origin traceability of organic pollutants

随着稳定同位素分析技术日趋发展完善,单体稳定同位素分析技术(compound-specific isotope analysis,CSIA)作为一种高分辨率、高灵敏度的同位素分析技术手段已逐渐受到关注。目前CSIA技术在有机污染物溯源方面的研究应用主要集中于卤代烃类、多环芳烃类及甲基叔丁基醚等,其在农药溯源领域的应用尚待研究开发。文章对CSIA技术在卤代烃类、多环芳烃类及甲基叔丁基醚等有机污染物溯源中的应用研究进展进行了总结与综述,讨论了该技术目前存在的问题,并分析了其在农药残留污染物溯源方面的应用前景,以期为CSIA技术在食品(特别是农产品)中农药残留污染溯源方面的开发应用提供参考。

With the increasing development of isotope analysis technology, compound-specific isotope analysis （CSIA） has become an advantaged analysis technology with high-resolution and high- sensitivity, and has gradually attracted great attention. At present, the application of CSIA in the origin traceability of organic pollutants mainly focus on in halohydrocarbons, PAHs and MTBE, and its application in the field of pesticide residue traceability remains to be researched. The application of CSIA in the traceability of organic pollutants （e.g. halohydrocarbons, PAHs and MTBE） is summarized in this review, which includes discussion about the problems existing in the traceability of organic pollutants, and application prospect in the field of pesticide residue traceability, which provides a reference for the development and application of CSIA in the traceability of food （especially agricultural products, etc.） pollutants.
