河北省桃果中农药残留分析

Analysis of pesticide residue in peach fruits in Hebei Province

为了安全使用农药,有效解决残留问题,给生产和建立综合指标体系提供科学依据,对河北省不同城市桃果中5种农药的残留情况进行测定分析,结果表明:桃果中甲氰菊酯残留量最高的是衡水,为0.062mg/kg;氯氟氰菊酯残留含量最高的是保定,为0.065mg/kg;氯氰菊酯残留量最高的是秦皇岛,其值为0.105mg/kg;氰戊菊酯残留量最高的是邯郸,其值为0.096 mg/kg;毒死蜱残留量最高的是秦皇岛,其值为0.131mg/kg;将河北省不同城市桃果中检测的5种农药残留量按等距离方法分为5级,多数市的桃果农药残留量位于Ⅰ、Ⅱ级,且5种检测农药中唐山市有4种农药残留量最小。

The experiment was conducted by measuring and analyzing the pesticide residue of peach fruits in different cities in Hebei Province,in order to realize the safety use of pesticides,and effectively solve the residual problems in production.The safety comprehensive index system was established to provide scientific basis for safe production.The results showed that peach fenpropathrin content in Hengshui peaches was the highest,reaching0.062 mg/kg;the highest cyhalothrin residue content was in Baoding peaches,reaching0.065mg/kg;the highest cypermethrin residual quantity was in Qinhuangdao peaches,reaching 0.105mg/kg;the highest volume of fenvalerate residue was in Handan peaches,reading 0.096mg/kg and the highest volume of chlorpyrifos was in Qinhuangdao peaches,reading 0.131mg/kg.There was no residues,although there were differences in the five residues amounts of peaches when detected.The residues was divided into five grades by distance method and most cities in Hebei Province were in the rank of I,II grade,and among the 5kinds of pesticides detected in Tangshan City,four pesticide residues were in the minimum.
