摘要:

分析2004-2012年平凉市蔬菜中农药残留现状,根据联合国粮食及农业组织农药残留联席会议建议的急性膳食摄入量计算方法,运用风险分析软件,基于蒙特卡洛模拟技术建立蔬菜农药残留急性膳食风险评估模型,对超标率和检出率高的蔬菜农药开展暴露风险评估。结果表明:在检测的26 个种类1 273 个样品中,有6 种蔬菜中的3 种农药残留存在膳食风险,即甘蓝中的敌敌畏、乙酰甲胺磷膳食风险概率分别为27.0%和22.5%,普通白菜中的敌敌畏膳食风险概率为32.0%,芹菜、大白菜、番茄、黄瓜中的甲氰菊酯膳食风险概率分别为29.4%、0.4%、0.8%、16.7%。平凉市部分蔬菜中农药暴露风险较高,应加强平凉市蔬菜中农药质量安全监管力度。

Abstract:

According to the method of Joint FAO/WHO Meeting on Pesticide Residues (JMPR), a risk assessment modelwas established based on the data of pesticide residues in vegetables marketed in Pingliang city, Gansu province during2004—2012 by Monte Carlo simulation with a risk analysis software to estimate the risk of dietary exposure to pesticideresidues exceeding the maximum residual limits (MRLs). The results showed that of 1 273 samples from 26 varieties ofvegetables tested, 6 vegetable varieties contained three kinds of pesticide residues which posed a health risk to consumers, witha risk possibility of 27.0% and 22.5% for dichlorvos and acephate in cabbage, respectively, 32.0% for dichlorvos in Chinesecabbage, and 29.4%, 0.4%, 0.8% and 16.7% for permethrin in celery, Chinese cabbage, tomato and cucumber, respectively.Thus, supervision should be strengthened due to the relatively high risk of dietary exposure to pesticide residues in somevegetables marketed in Pingliang city.
