本文介绍了首次对哈萨克斯坦粮食中农药残留的研究结果。共收集了80个样品：大麦，燕麦，黑麦和小麦，并在认可的实验室进行了测试。在180种农药中，检出10种活性物质。在谷物中发现了禁用的杀虫剂，如滴滴涕、γ-六氯环己烷、艾氏剂和二嗪农。甲基毒死蜱和甲基嘧啶磷是最常见的残留物。在77.5%的样品中未发现农药残留，13.75%的样品中农药残留达到或低于MRL，8.75%的样品中农药残留超过MRL。小麦中残留物样品的百分比最高（29%），黑麦最低（20%）。获得的数据被用来估计与接触这些农药有关的潜在健康风险。最高估计日摄入量如下：艾氏剂（小麦）每日允许摄入量的789%，甲基嘧啶磷（小麦和黑麦）每日允许摄入量的49.8%。小麦中艾氏剂和戊唑醇的急性风险分别为315.9%和98.7%。结果表明，尽管谷物中农药残留的EDIs最高，但目前的情况不能被认为是一个严重的公共卫生问题。尽管如此，建议对粮食中农药残留的连续监测进行调查。(C)2013爱思唯尔有限公司保留所有权利。
This paper presents the first study of pesticide residue results in grain from Kazakhstan. A total of 80 samples: barley, oat, rye, and wheat were collected and tested in the accredited laboratory. Among 180 pesticides, 10 active substances were detected. Banned pesticides, such as DDTs, gamma-HCH, aldrin and diazinon were found in cereal grain. Chlorpyrifos methyl and pirimiphos methyl were the most frequently detected residues. No residues were found in 77.5% of the samples, 13.75% contained pesticide residues at or below MRLs, and 8.75% above MRLs. The greatest percentage of samples with residues (29%) was noted for wheat, and the lowest for rye (20%). Obtained data were used to estimate potential health risks associated with exposure to these pesticides. The highest estimated daily intakes (EDIs) were as follows: 789% of the ADI for aldrin (wheat) and 49.8% of the ADI for pirimiphos methyl (wheat and rye). The acute risk from aldrin and tebuconazole in wheat was 315.9% and 98.7% ARID, respectively. The results show that despite the highest EDIs of pesticide residues in cereals, the current situation could not be considered a serious public health problem. Nevertheless, an investigation into continuous monitoring of pesticide residues in grain is recommended. (C) 2013 Elsevier Ltd. All rights reserved.
