摘　　要：本文对土壤中农药成分典型特征刻画进行了探索性研究,为实现土壤质量的动态管理、土壤污染犯罪的判定及土壤检材的选取提供技术依据。本文还对我国某地圣女果种殖基地土壤中的农药成分和含量进行了分析,应用气相色谱/质谱联用技术(GC/MS)检出灭蝇胺、百菌清、精甲霜灵和马拉硫磷等4种农药成分,并对土壤的提取部位、提取深度及在法庭科学领域用于推断地域、推断用途、推断时间和特征比对等应用前景进行了探讨,为今后系统开展土壤中农药成分典型特征刻画技术研究打下了基础。With coining the concept on characterization of soil-deposited pesticide components,an expatiation was conducted about the significance of the relevant studies and methods along with the difficulties and prospect.Such kind of systematic researches can not only support case investigation and litigation through providing scientific basis for identification of the selected evidential soil materials but also help realize the soil quality management dynamically,therefore capable of supplying technical foundation for judging the crime of soil pollution.In this paper,the pesticide composition and content were analyzed with the soil from a China’s cherry-tomato planting-and-seeding base.Four kinds of pesticides,cyromazine,chlorothalonil,mefenoxam and malathion,were detected with gas chromatography-mass spectrometry(GC-MS).Additionally,both the position and depth of the soil extracted were tested of their effect on the pesticide residue.Consequently,a discussion was made on the outlook of inferring whereabouts,usage,applied time and specific comparison about the involved pesticides.
