2022年湖北地区市售葡萄中农药残留特征及膳食暴露风险评估

Characteristics of Pesticide Residues and Dietary Exposure Risk Assessment on Commercial Grapes of Hubei Province in 2022

  • 摘要: 为了探讨湖北地区市售葡萄中农药残留特征以及其膳食暴露风险,本研究采用液相色谱串联质谱法和气相色谱串联质谱法对2022年湖北地区大型水果农贸市场和超市的128份葡萄样品中的46种农药残留进行分析,并采用英国兽药残留委员会兽药残留风险排序矩阵和食品安全指数法对检出的农药残留进行膳食暴露评估。结果表明,本次抽检的葡萄农药残留检出率为78.1%,有4个样品中的氯氟氰菊酯超标,超标率为3.1%,共检出20种农药,其中有9种未登记农药。根据残留风险得分,检出的农药中有阿维菌素、三唑醇、甲基硫菌灵等7种高风险农药,噻虫嗪、戊唑醇、啶虫脒、氯氰菊酯4种中风险农药,烯酰吗啉、嘧菌酯、抑霉唑等9种低风险农药。按照风险指数排序,中风险样品占3.1%,低风险和极低风险样品占96.9%。根据食品安全指数法的结果,20种检出农药的食品安全指数(IFS)值都低于1,说明膳食暴露风险在可接受的范围内。总体来说,本次监测的湖北葡萄样品质量安全状况良好,农药残留引起的膳食暴露风险较低。

     

    Abstract: To investigate the residue characteristics of pesticides in commercial grapes in Hubei and their dietary exposure risk, 46 pesticide residues in 128 grape samples from large-scale local markets and supermarkets of Hubei Province in 2022 were analyzed by liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry. The dietary exposure of detected pesticides in grapes was assessed by the veterinary drug residues risk ranking matrix of the UK Veterinary Drug Residues Commission and the index of food safety (IFS). The results showed that the detection rate of the pesticide residue in grapes was 78.1%. Moreover, cyhalothrin detected in four samples exceeded the national maximum residue limit of pesticide and the exceeding rate was 3.1%. According to the residual risk score, there were 7 high-risk pesticides (avermectin, triazole alcohol and thiophanate-methyl, etc), 4 medium-risk pesticides (thiamethoxam, tebuconazole, acetamiprid and cypermethrin) and 9 low-risk pesticides (enoylmorpholine, azoxystrobin and imazalil, etc) among the pesticides detected. Based on the results of risk index, medium-risk samples accounted for 3.1%, and low-risk and very low-risk samples accounted for 96.9%. On the basis of the results of the food safety index method, the IFS values of 20 pesticides detected were lower than 1, indicating that the dietary exposure risk was within an acceptable range. In general, the grape samples monitored in this study had good safety characteristics and low health risks.
