6个城市的蔬菜农药残留检测分析

Study on Pesticide Residues of Organophosphorus and Pyrethroid in Vegetables from Hubei Province

采用农药多残留快速检测技术,用气相色谱仪(FPD和μECD)检测了宜昌等6个城市8个蔬菜品种54个蔬菜样品中有机磷和拟除虫菊酯类农药残留。结果表明,有21个样品检出农药,检出率为38.9%,其中有4个样品超标,超标率为7.4%。农药生产销售监管不严是造成蔬菜农药残留超标的主要原因,大力推广无公害、绿色蔬菜生产技术,引导农民合理正确用药是解决问题的重要途径。

Organophosphorus and pyrethroid pesticide residues of the fifty-four samples were detected by GC（FPD and μECD） which were selected from eight breeds of vegetable from Yichang and other five cities in Hubei province using the technology of monitoring multi-class pesticide residues in farm product. The pesticide was found in twenty-one samples and the detection rate was 38.9%. The residue contentsin four samples were over the MRLs, and the detection rate was 7.4%. Invalid supervising of the pestcide producing and sales greatly resulted in that the pestcide in the vegetables were over the MRLs. Therefore, spreading nuisance-free green vegetables and inducing famers to use the pestcide properly were urgency, which are the most excellent and necessary way to solve the problem.
