Study and Application of Analytical Method for Pesticide Residues in Tobacco, Vegetables and Fruits by GC-EI/MS

Abstract

化学农药在防治农作物病虫害的同时也给人类与环境带来了负面影响,食品的质量 与安全是决定人类生存质量的重要因素之一。农药残留问题是目前影响食品安全的首要 问题,一直被世界各国政府和组织所关注,随着世界各国对食品中农药残留种类的要求 越来越多、最高农药残留限量标准的要求越来越低,研究与建立行之有效的农药残留分 析方法,以保证食品的质量与安全和促进农产品的出口贸易十分必要。 本学位论文致力于食品中有机氯类、有机磷类和拟除虫菊酯类农药的农药残留分析 方法研究,优化了气相色谱-电子轰击电离源/质谱联用法(GC-EI/MS)的分析条件,探讨 了水果保鲜剂中农药组分对水果中农药残留的影响,初步...Pesticide is a double-edged sword, it protects agriculture products from destroyed by plant diseases and insect pests and provides benefits in increasing crop production while it has a negative impact or even a threat to human and environment as well. The quality and safety of food is crucial to human’s life while the pesticide residue is one of the most important problems which attract much att...学位:理学硕士院系专业:化学化工学院化学系_分析化学学号:2052006115192
