摘要
甘肃省平凉市农产品质检中心承担的2017—2021年5年市级例行监测任务中使用气相色谱-质谱联用法、液相色谱-串联质谱法测定58种农药。检测数据发现,232份设施番茄样品中腐霉利和烯酰吗啉农药残留合格率均为100%,但检出率分别21.55%和6.03%,相对其他农药检出率比较高;在检出腐霉利农药中有54%残留量分布在0.02~0.22 mg/kg范围,检出烯酰吗啉农药中有79%残留量分布在0.0001~0.1001 mg/kg范围,检出残留量相对比较集中,且2种农药的最高检出值均低于该农药最大残留限量值(MRL)。结果显示:腐霉利和烯酰吗啉慢性膳食摄入风险分别为1.21%和0.165%,均远小于100%。急性膳食摄入风险分别为8.06%和0.291%,远小于100%,急性和慢性风险均在可接受范围内;腐霉利和烯酰吗啉的风险得分分别为10.43和10.12,残留风险相对比较低,处于低风险水平。
58 kinds of pesticides were determined by GC-MS/MS and LC-MS/MS in the five-year municipal routine monitoring task undertaken by Pingliang Agricultural Products Quality Safety Inspection and Testing Center of Gansu Province from 2017 to 2021.The test data showed that the qualified rates of the residues of procymidone and dimethomorph were 100% in 232 tomato samples,but the detection rates were 21.55% and 6.03%,respectively,which were higher than other pesticides.Among the detected humus pesticides,54% of the residues were distributed in the range of 0.02-0.22 mg/kg,and 79% of the detected dimethomorph pesticides were distributed in the range of 0.0001-0.1001 mg/kg,the detected residues were relatively concentrated,and the highest detected values of the two pesticides were lower than the maximum residual value of the pesticide(MRL).The results showed that the risks of chronic dietary intake were 1.21% and 0.165%,respectively,which were far less than 100%.Acute dietary intake risks were 8.06% and 0.291%,respectively,far less than 100%,and both acute and chronic risks were within the acceptable range.The risk scores were 10.43 and 10.12,respectively,indicating that the residual risk was relatively low and at a low risk level.
