【摘要】 对重庆市的蔬菜生产基地、大型批发市场、农贸市场和超市的7大类蔬菜中的13种农药残留进行抽样监测。结果表明,重庆蔬菜农药残留超标率呈先上升后下降的变化趋势,农药残留平均超标率是豆类>甘蓝类>茄果类>白菜类>绿叶菜类>瓜类>根菜类,市场>基地,外地>本地;除了3月份的氧化乐果对蔬菜安全影响的风险超过了可以接受的限度外,其余月份各种农药残留的安全指数都小于1,对蔬菜安全影响的风险和蔬菜安全状态为可以接受;蔬菜中的甲胺磷、乙酰甲胺磷、甲拌磷、氧化乐果和百菌清残留的R(风险系数)>1.5,处于高、中度风险状态,其余农药皆处于低度风险状态。更多还原

【Abstract】 Thirteen pesticide residues in eight kinds of vegetables of whole sale marketplaces,retail marketplaces,supermarkets,vegetable bases in Chongqing were detected in each quarter during a whole year.The study showed that the dynamic changes of general pesticide residues ascended earlier,then descended.The excessive rates were as follows: legumes>cabbages> aubergine and fruits> chinese cabbages> green-leaf vegetables > cucurbits > root vegetables,marketplaces > vegetable bases,external places >local.Except the risk of omethoate was over acceptable limite in march,the safety index of all pesticides were less than 1 and the safety states were acceptable in other months.The residues risk coefficients of(R) methamidophos,acephate,phorate,omethoate,chlorothalonil were more than 1.5,which were in high or moderate safety states,and other pesticides were all in low safety states.更多还原
