Abstract

To assess the dietary exposure risks of pesticide residues in vegetables for the general population, the presence of 39 pesticides was determined in 70 samples, of which 13 were detected. The most frequently detected pesticide was bifenthrin, with a detection rate of 35.7%, mainly found in gingers, followed by isoprocarb and acephate (11.4%) and dimethoate (8.6%). In 17.1% of the samples two or more pesticide residues were found. Acute, chronic and chronic cumulative dietary exposure risk was assessed. Chronic exposure risks were determined by Monte Carlo Simulation (MCS). Estimated chronic exposure to carbofuran, omethoate, disulfoton and dimethoate of approximately 49%, 52%, 40% and 3%, respectively, were at non-carcinogenic human risk. Acute exposure risk to acephate was considered to be of concern due to the high acute hazard quotient (aHQ).

中国甘肃省蔬菜中的农药残留及蒙特卡罗模拟风险评估。

为评估一般市民从膳食摄入蔬菜残余除害剂的风险，我们在 70 个样本中检测了 39 种除害剂，其中 13 种被检出。最常检测到的除害剂是联苯菊酯，检出率为 35.7%，主要存在于蘘荷中，其次是异丙威和乙酰甲胺磷（11.4%）和乐果（8.6%）。在 17.1%的样本中，发现了两种或两种以上的残留农药。评估了急性、慢性和慢性累积膳食暴露风险。慢性接触风险是通过蒙特卡罗模拟（MCS）确定的。呋喃丹、氧化乐果、二磺酰草胺和乐果的估计慢性接触风险分别约为 49%、52%、40% 和 3%，属于非致癌风险。由于乙酰甲胺磷的急性危害商数（aHQ）较高，因此认为其急性接触风险值得关注。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
