[目的]了解广州市2009年春节前超市所售各类蔬菜以及各系列“放心菜”中有机磷和氨基甲酸酯类农药的残留情况,为有关部门于春节前加强蔬菜上市及销售环节的管理提供科学依据,并为市民节前对蔬菜的选购及食用做出相应指导。[方法]采用整体测定法,使用农药速测卡快速检验方法,对广州市4大超市的蔬菜进行抽样检测。[结果]4家超市共108份蔬菜样品中有机磷和氨基甲酸酯类农药残留超标检出率达45.37%;其中无标识的叶菜类蔬菜有机磷和氨基甲酸酯类农药残留超标检出22份,检出率为52.38%,有标识的“放心菜”共检出10份,检出率为28.57%,两者有显著性差别。而其中包菜、奶白菜、油麦菜、菠菜、白菜、芥菜等是农药残留较高的几种常食用的蔬菜。[结论]节前各超市有标识的“放心菜”的农药残留合格率比无标识的普通蔬菜要低,但总体的农药污染情况比较严重。监管部门应引起重视,消费者在选购时也应谨慎选择,尽量选购绿色安全产品,对于买回家的蔬菜,也要进行去除残留农药的处理。
