摘要
调查长春市市售蔬菜的农药残留水平,并评估其对人体健康的潜在风险。2021年在长春市地区共采集352个蔬菜样本,采用液相色谱串联质谱法和气相色谱串联质谱法对76种农药残留分析,并评估慢性膳食摄入风险和急性膳食摄入风险。结果表明,蔬菜样品中,183个样品(51.99%)未检出农药残留,169个样品(48.01%)含有农药残留,16个样品(4.55%)残留超过最大残留限量(MRLs)。共检出28种不同农药残留,10种农药残留超过MRLs。检出频率前三位的农药残留为腐霉利、啶虫脒、多菌灵。在韭菜、芹菜、菠菜、茄子、豇豆、葱中发现超过MRLs的样本。4个季度中,农药超标风险为第一季度>第四季度>第三季度>第二季度。膳食摄入风险评估结果显示:养乐果的%ADI为108.33%,慢性摄入风险不可接受;克百威的%ARfD为291.67%,急性摄入风险不可接受。其余各类农药的急性和慢性膳食摄入风险值均小于100%。长春市市售蔬菜中农药残留检出率较高,但超标率较低,整体合格率高,但存在不同程度慢性和急性摄入风险,建议相关部门加大监测和监管力度。
Investigate the level of pesticide residues in vegetables sold in Changchun,and evaluate their potential risks to human health.About 352 vegetable samples were collected in Changchun in 2021.About 76 pesticide residues were analyzed by liquid chromatography tandem mass spectrometry(LC-MS)and gas chromatography tandem mass spectrometry(GCMS),and chronic dietary intake risk and acute dietary intake risk were assessed.The results showed that in the vegetable samples,183 samples(51.99%)did not detect pesticide residues,169 samples(48.01%)contained pesticide residues,and 16 samples(4.55%)exceeded the maximum residue limits(MRLs).About 28 different pesticide residues were detected,and 10 samples of those exceeded MRLs.The top three pesticide residues detected were pythil,acetamiprid and carbendazim.The samples exceeding MRLs were found in leek,celery,spinach,eggplant,cowpea and onion.In the four quarters,the risk of pesticide exceeding was the 1^(st)>4^(th)>3^(rd)>2^(nd).The results of dietary intake risk assessment showed that%ADI of omethoate was 108.33%,and the risk of chronic intake was unacceptable;%ARfD of carbofuran was 291.67%,and the acute intake risk was unacceptable.The risk values of other pesticides in acute and chronic dietary were less than 100%.In the commercial vegetables of Changchun City,the detection rate of pesticide residues was high,but the rate of exceeding was low;The overall qualification rate was high,but there were risks of chronic and acute ingestion to varying degrees.It was suggested that relevant departments should strengthen monitoring and supervision.
