摘　　要：为了解河南产大宗水果中农药残留情况,为水果安全食用提供指导,基于酶抑制法检测了10种水果中有机磷和氨基甲酸酯类农药的残留。结果表明,不同种类水果以及同一种水果不同批次之间有机磷和氨基甲酸酯类农药残留有较大差异,抑制率为0~75.55%,在50个批次检测样品中,有48个批次的水果中农药残留符合农业行业限定标准,合格率为96%;残留农药主要集中在果皮中,而清洗显著降低了农药在水果中的残留。To explore the pesticide residues in the main fruits produced in Henan province and provide guidance for the safe consump⁃tion of fruits,random samples were taken from different fruit markets in Zhengzhou city,and the residues of organophosphorus pesti⁃cides(Ops)and carbamate pesticides(CPs)in 10 kinds of fruits were detected using enzyme inhibition method.The results showed that different amount of OPs and CPs residues were detected among different kinds of fruits and different batches of the same fruit.The inhibition rate of cholinesterase by OPs and CPs was in the range of 0 to 75.55%in total of 50 batches of fruits,and the enzyme inhibi⁃tion rates in 48 batches of fruits were less than 70%,96%of the samples were in accordance with the agricultural industry standards.Residual pesticides were mainly concentrated in the peel,and the residues of OPs and CPs could be effectively reduced by washing.
