摘　　要：采用食品安全指数和风险系数模型,初步建立了农药残留膳食暴露风险和预警风险评估体系。开发"风险值自动计算—信息多维采集与分析"定制软件,基于2012—2015年我国市售果蔬农残检测大数据,从农药种类、限量标准、果蔬种类、地域等多个维度,分别对果蔬中残留农药之于人体的膳食暴露风险、预警风险进行了评估和解析。结果显示,气相色谱-四极杆-飞行时间质谱(GC-Q-TOF/MS)和液相色谱-四极杆-飞行时间质谱(LC-Q-TOF/MS)技术侦测的9 823例和12 551例市售果蔬,绝大多数膳食风险为可接受,但仍有0.56%和0.54%为风险不可接受。禁用农药膳食暴露风险不可接受比例是非禁用农药的20倍(GC-Q-TOF/MS组)和55倍(LC-Q-TOF/MS组);禁用农药高度预警风险比例是非禁用农药的17倍(GC-Q-TOF/MS组)和23倍(LC-Q-TOF/MS组),可见农药残留风险亟需控制,尤其应严格监管"禁药禁用"。文章据以上评估给出了高风险排名前10的农药和果蔬。另外,还发现欧盟的农药最大残留限量标准(MRLs)明显严于我国,我国相关标准建立亟待加快。研究结果可作为果蔬等食品风险水平实时诊断和风险农药精准监管的重要依据,以减少食源性农药残留风险,保障食品安全。Two systems of dietary exposure and prewarning risk assessment of pesticide residue were constructed using models of food safety index and risk coefficient, respectively. A customized software of risk value automatic calculation-multidimensional information collection was developed.The risks of pesticide residues in the marketed fruit and vegetable samples in China from 2012 to 2015 were assessed on the basis of detection data.Multi-dimensional information was collected and analyzed including fruit and vegetable species,pesticide category,regions,maximum residue limit standards,and so on.The assessment results of dietary exposure risk indicate that the majority of risks are acceptable in the marketed fruits and vegetables of 9 823（LC-Q-TOF/MS）and 12 551 samples（LC-Q-TOF/MS）,respectively,but there are still 0.56%and 0.54%of them unacceptable.By the comparison of prohibited and non-prohibited pesticides,the frequency ratios of unacceptable dietary risks in total frequency are hiked at 20（GC-Q-TOF/MS）and 55（LC-Q-TOF/MS）times,while the ratios of high prewarning risk are 17（GC-Q-TOF/MS）and 23（LC-Q-TOF/MS）times respectively.The risks of the prohibited pesticides are significantly higher than that of the non-banned pesticides.Strict supervision and regulation of banned pesticides should be strengthened.The top fruits and vegetables with unacceptable dietary exposure risks of high prewarning risk are listed in this study.In addition,it could be found that the maximum residual limit standards established by European Union were obviously more strict and complete than that of China,so China must speed up the establishment of relevant standards.This study could provide important basis for real-time diagnosis and precise supervision of risk level of fruits and vegetables,thus reduce the risk of food borne pesticide residues and ensure people’s tongue safety.
