摘要: 目的】开展苹果农药残留风险评估研究,为苹果消费、农药残留监管和农药最大残留限量(MRLs)制修订提供科学依据。【方法】对采自主产区的200个苹果样品进行农药残留检测,分别用%ADI%ARfD进行农药残留慢性膳食摄入风险评估和急性膳食摄入风险评估,用ADI值、大份餐和体重计算最大残留限量估计值(eMRL),借鉴英国兽药残留委员会兽药残留风险排序矩阵进行农药和样品风险排序。【结果】⑴ 检测的102种农药中26种农药检出残留,检测的200个样品中189个样品检出农药残留,仅有1个样品农药残留超标(超标农药为氧乐果);⑵ 检出残留的26种农药,其慢性膳食摄入风险(用%ADI表示)在0.00%—1.07%,平均值为0.13%;其急性膳食摄入风险(用%ARfD表示)在0.18%—22.41%,平均值为4.12%;⑶ 根据残留风险得分,检出残留的26种农药可划分为3类,即高风险农药(8种)、中风险农药(10种)、低风险农药(8种);⑷ 以风险指数排序,风险高的样品仅占1.5%,风险中、低和极低的样品占98.5%;⑸ 在检出残留的26种农药中,灭幼脲可不制定MRL,氟硅唑等6种农药的MRLs过严,乐果等5种农药的MRLs过松,建议矮壮素、苯醚甲环唑、虫酰肼、二嗪磷、氟硅唑、甲基硫菌灵、乐果、联苯菊酯、氯氟氰菊酯、氰戊菊酯、炔螨特、噻嗪酮、三氯杀螨醇、杀扑磷、戊唑醇、烯唑醇、亚胺硫磷和抑霉唑的MRLs分别设定为4、1、2、0.5、0.6、7、0.2、1、2、2、1、0.8、0.2、0.1、3、0.5、1和3 mg·kg-1。【结论】苹果农药残留检出率相对较高,但99.5%的苹果样品其农药残留量均低于MRLs。苹果农药残留慢性膳食摄入风险和急性膳食摄入风险均很低。苹果应重点关注氧乐果、磷胺、杀扑磷、毒死蜱、二嗪磷、联苯菊酯、亚胺硫磷和乐果残留。建议修订或制定苹果中矮壮素等18种农药的MRLs。

Abstract: 【Objective】Risk assessment of pesticide residues in apples will provide a scientific basis for apple consumption, apple pesticide residue supervision, and establishment of maximum residue limits (MRLs) for pesticides in apple. 【Method】Residues of 102 pesticides in 200 apple samples from main producing areas in China were detected. Chronic dietary intake risk and acute dietary intake risk of pesticide residues in these samples were assessed, respectively, by %ADI and %ARfD. Estimated maximum residue limits (eMRLs) of 26 pesticides with detectable residues were calculated by ADIs, large portion of apple, and body weight of consumer. The Matrix Ranking developed by the Veterinary Residues Committee of the United Kingdom was referred to rank the risk of pesticides and apple samples.【Result】25.5% of pesticides (26/102) and 89.5% of apple samples (179/200) had detectable residues. 0.5% of apple samples contained residue above the MRL (of omethoate). For 26 pesticides with detectable residues, their chronic dietary intake risks expressed as %ADI were 0.00%-1.07% with an average of 0.13%, and their acute dietary intake risks expressed as %ARfD were 0.18%-22.41% with an average of 4.12%. These 26 pesticides were divided into 3 groups by risk score, i.e. high risk group (8 pesticides), medium risk group (10 pesticides), and low risk group (8 pesticides). Apple samples studied were ranked by risk index, 1.5% of which had high pesticide residue risk, and 98.5% of which had medium, low, or lower pesticide residue risk. Among 26 pesticides with detectable residues, it is unnecessary for chlorbenzuron to establish MRL in apple, MRLs of 6 pesticides (e.g. flusilazole) are overly strict, MRLs of 5 pesticides (e.g. dimethoate) are overly loose, and MRLs of 18 pesticides (including chlormequat, difenoconazole, tebufenozide, diazinon, flusilazole, thiophanate-methyl, dimethoate, bifenthrin, cyhalothrin, fenvalerate, propargite, buprofezin, dicofol, methidathion, tebuconazole, diniconazole, phosmet, and imazali) were proposed to be 4, 1, 2, 0.5, 0.6, 7, 0.2, 1, 2, 2, 1, 0.8, 0.2, 0.1, 3, 0.5, 1, and 3 mg•kg-1, respectively.【Conclusion】Pesticide residues in Chinese apples had a relatively high detection rate, but pesticide residues in 99.5% of samples were under MRLs. Both chronic and acute dietary intake risks of pesticide residues in Chinese apples were very low. Residues of 8 pesticides in apples should be focused on, including omethoate, phosphamidon, methidathion, chlorpyrifos, diazinon, bifenthrin, phosmet, and dimethoate. And MRLs for 18 pesticides (e.g. chlormequat) in apples were proposed to be established or revised.
