中文摘要:

      目的 调查主产区广西、广东、福建及海南杨桃中农药残留状况, 评估其农药残留风险。方法 对在主产区采集的70份杨桃中105种农药残留进行检测, 并对检出的农药残留慢性膳食摄入风险(percent of acceptable daily intake, %ADI)、急性膳食摄入风险(percent of acute reference dose, %ARfD)进行评估及风险排序。结果 在70份杨桃中共有53份样品检出农药残留, 检出率为75.7%; 检出的农药共有18种, 检出最多的前3位是多菌灵、甲基毒死蜱、啶虫脒, 检出率分别为42.8%、17.1%、15.7%; 检出农药的%ADI均值为2.03%; %ARfD均值为5.89%, 所有农药残留风险值均低于100%, 风险很低。杨桃中高风险农药是灭多威、3-羟基克百威、三氯杀螨醇3种。结论 主产区杨桃中农药残留慢性膳食摄入风险和急性膳食摄入风险均很低, 在杨桃安全生产和消费、质量安全监管中应对高风险农药重点关注, 建议加快对杨桃中使用农药的登记和最大残留限量的制修订。

英文摘要:

      Objective To investigate the pesticide residues in carambola in the main producing areas as Guangxi, Guangdong, Fujian and Hainan, and evaluate the risk of pesticide residues. Methods 105 kinds of pesticides residues in 70 carambola samples collected from main producing areas were detected. The risk of chronic dietary intake of pesticide residues (percent of acceptable daily intake, %ADI) and the risk of acute dietary intake (percent of acute reference dose, %ARfD) were evaluated and ranked. Results Pesticide residues were detected in 53 samples of 70 carambola samples, the detection rate was 75.7%. There were 18 pesticides detected, the top three detected were carbendazim, chlorpyrifos methyl, acetamiprid, the detection rates were 42.8%, 17.1%, 15.7%, respectively. The mean value of %ADI of pesticides detected was 2.03%. The mean value of %ARfD was 5.89%, and the risk value of all pesticide residues was lower than 100%, so the risk was very low. Methomyl, 3-hydroxycarbofuran and dicofol were 3 kinds of high-risk pesticides in carambola. Conclusion The risk of chronic dietary intake and acute dietary intake of pesticide residues in carambola in the main producing areas are very low. High risk pesticides should be paid more attention in the safe production and consumption of carambola, and quality and safety supervision. It is recommended to speed up the registration of pesticides used in carambola and the revision of maximum residue limits.
