中文摘要：本文旨在定量检测温室黄瓜中乙硫磷和吡虫啉农药残留，分析储存、清洗和剥皮等处理程序对乙硫磷和吡虫啉农药残留量的影响。实验结果发现，施药一小时后，乙硫磷和吡虫啉农药残留量均超过国际食品残留标准水平，施药一天后，乙硫磷和吡虫啉农药残留量分别降低了35%和31%，但依然高于最大残留值。清洗处理能够使乙硫磷和吡虫啉农药残留量分别减少51%和42.5%，剥皮处理可使乙硫磷和吡虫啉农药残留量最高分别减少93.4%和63.7%，回收率范围为88%-102%。因此，存储、清洗和剥皮等处理程序是去除温室产品农药残留的简单有效的方法。
外文摘要：Background: The objective of this study was to determine the residual concentrations of ethion and imidacloprid in cucumbers grown in greenhouse. The effect of some simple processing procedures on both ethion and imidacloprid residues were also studied. Methods: Ten active greenhouses that produce cucumber were randomly selected. Ethion and imidacloprid as the most widely used pesticides were measured in cucumber samples of studied greenhouses. Moreover, the effect of storing, washing, and peeling as simple processing procedures on both ethion and imidacloprid residues were investigated. Results: One hour after pesticide application; the maximum residue levels (MRLs) of ethion and imidacloprid were higher than that of Codex standard level. One day after pesticide application, the levels of pesticides were decreased about 35 and 31% for ethion and imidacloprid, respectively, which still were higher than the MRL. Washing procedure led to about 51 and 42.5% loss in ethion and imidacloprid residues, respectively. Peeling procedure also led to highest loss of 93.4 and 63.7% in ethion and imidacloprid residues, respectively. The recovery for both target analytes was in the range between 88 and 102%. Conclusion: The residue values in collected samples one hour after pesticides application were higher than standard value. The storing, washing, and peeling procedures lead to the decrease of pesticide residues in greenhouse cucumbers. Among them, the peeling procedure has the greatest impact on residual reduction. Therefore, these procedures can be used as simple and effective processing techniques for reducing and removing pesticides from greenhouse products before their consumption.
