Abstract

Abstract: 531 vegetable samples were collected from the vegetable bases of 20 districts and counties in Chengdu city from 2017 to 2019.66 kinds of pesticides were detected by GB 23200.19—2016,GB/T 5009.144—2003,SN/T 3643—2013 and NY/T 761—2008.The results were determined according to GB 2763—2016.The results showed that in all the samples,32 pesticide residues were detected in 92 vegetable samples,and the detection rate of pesticide was 17.33%.One sample exceeds the standard,nine samples detected banned pesticides chlorpyrifos and fipronil,the unqualified rate was 1.88%.Leaf vegetables accounted for 39.13% of the detected samples,and seven samples were unqualified,accounting for 70.00% of the total unqualified rate.Pesticide residues in vegetables are widely used,especially in leaf vegetables.It is necessary to strengthen pesticide quality management,strengthen standardized production management,improve pesticide residue limit standards,increase the investigation and disposal of banned pesticides,increase the frequency of detection in bases and markets,and reduce the impact of pesticide residues on human beings and the environment.

Key words: vegetables, pesticide residue, detection, analysis
