渝东北地区常见果蔬中6种农药残留量分析与安全性评价
Analysis and safety evaluation of six pesticide residues in fruits and vegetables in northeast Chongqing
摘要
Abstract
[Objective]To understand the residue status of six pesticides in fruits and vegetables in northeast Chongqing and the associated health risks to local residents.[Methods]Six pesticides were detected and evaluated for safety using gas chromatography combined with the index of food safety(IFS).[Results]Among the six pesticides,dieldrin was not detected,while the remaining five pesticides were detected.The average residual concentrations of the five pesticides in seven types of fruits and vegetables were as follows:procymidon 0.265 mg/kg,biphenthrin 0.037 mg/kg,beta-cyfluthrin 0.073 mg/kg,cypermethrin 0.060 mg/kg,and deltamethrin 0.025 mg/kg.Among all the samples,beta-cyfluthrin had the highest detection rate(25.34%),followed by procymidon(18.46%),with deltamethrin having the lowest detection rate(5.52%).The exceedance rate was highest for beta-cyfluthrin(1.00%),followed by procymidon(0.90%),while deltamethrin had the lowest exceedance rate(0.09%).The safety evaluation showed that both the single-pesticide average IFS and multiple-pesticide average IFS for the five detected pesticides were all less than 1.[Conclusion]The fruit and vegetable samples sold in northeast Chongqing do not pose significant health risks to humans.关键词
