摘要
为了了解岳阳市蔬菜水果中农药残留状况和膳食摄入风险,以 2023 年岳阳市 736 份蔬菜水果样品为对象,采用气相色谱质谱联用仪和高效液相色谱仪对 36 种农药残留进行定量分析,并对样品中检出的农药进行风险评估.结果表明:蔬菜农药残留检出率为 39.71%,超标率为 0.33%;水果农药残留检出率为 64.52%,超标率为 0.81%.蔬菜中农药残留检出率最高为啶虫脒(14.38%),超标率最高为噻虫嗪(0.16%)和吡虫啉(0.16%);水果中农药残留检出率最高为氯氟氰菊酯(41.18%),超标率最高为多菌灵(2.44%).蔬菜中茄果类农药残留的检出率(65.77%)最高,豆类超标率(3.23%)最高;水果中柑橘类农药残留的检出率(100%),超标率(25.00%)最高.在检出农药残留的蔬菜水果样品中,有 44.86%的蔬菜和 50.00%的水果检出 2 种及以上的农药.蔬菜水果中各类农药的%ADI和%ARfD均小于 100%;单项农药的IFSmax、IFSc和总体农药IFSi均小于 1.研究表明,岳阳市蔬菜水果中存在不同程度的农药残留污染,但其引起的膳食摄入风险较低,监管部门仍需加强对蔬菜水果农药残留监测和农药使用管理.
Abstract
To understand the status of farm chemical residues in vegetables and fruits in Yueyang City and the dietary intake risks for residents,we collected 736 samples of vegetables and fruits from Yueyang City in 2023.Gas chromatography-mass spectrometry and high-performance liquid chromatography were used for quantitative analysis of residues of 36 farm chemicals.Risk assessment was carried out for the detected residues in the samples.The results showed that the detection rates of farm chemical residues in vegetables and fruits were 39.71%and 64.52%,with the over-limit rates of 0.33%and 0.81%,respectively.In vegetables,acetamiprid(14.38%)was the farm chemical with the highest detection rate,and thiamethoxam(0.16%)and imidacloprid(0.16%)had the highest over-limit rate.In fruits,cyhalothrin(41.18%)had the highest detection rate and carbendazim(2.44%)had the highest over-limit rate.Among vegetables,solanaceous vegetables(65.77%)had the highest detection rate of farm chemicals,and legumes had the highest over-limit rate(3.23%).Among fruits,citrus fruits had the highest detection rate(100%)and over-limit rate(25.00%).In addition,44.86%of vegetable samples and 50.00%of fruit samples were detected with two or more farm chemicals.The%ADI and%ARfD were less than 100%for all the farm chemicals in vegetables and fruits.The maximum index of food safety(IFSmax),chronic IFS(IFSc),and integrated IFS(IFSi)for individual farm chemicals were all less than 1.The results suggest that farm chemical residues exist in vegetables and fruits in Yueyang City,while the resulting dietary intake risks are relatively low.Nonetheless,regulatory authorities still need to enhance monitoring of farm chemical residues in vegetables and fruits and improve the management of farm chemical use.
