鲜食性蔬菜农药残留对人体健康急性膳食风险评估

The Acute Dietary Risk Assessment of Pesticide Residues from Fresh Edible Vegetables for Human Health

由于蔬菜生产者施用农药的水平较低,导致消费者偶然摄入含高浓度农药残留的可能性增加。以已制定急性参考剂量(ARfD值)的农药为范围,选用甘肃省平凉市2008—2011年例行检测中黄瓜等6种鲜食性蔬菜中的敌敌畏等24种农药残留资料,应用JMPR急性膳食摄入量计算方法进行了急性膳食风险评估。黄瓜中甲氰菊酯、氧乐果风险概率分别为0.2069、0.0143;番茄中甲氰菊酯风险概率为0.0714;大白菜中敌敌畏和甲氰菊酯风险概率均为0.0417;甘蓝中敌敌畏、乙酰甲胺磷、甲氰菊酯风险概率分别为0.0930、0.0385、0.0370;青椒中甲氰菊酯风险概率为0.0217;长辣椒中敌敌畏风险概率为0.0526。甲氰菊酯、氧乐果、敌敌畏、乙酰甲胺磷4种农药有急性膳食风险,其他农药均无急性膳食风险。

The pesticide application level of the producers of vegetables was lower, so caused the consumer to accidental ingestion possibility of containing high concentrations of pesticide residues increase. In the range of ARfD made by JMPR, the paper adopted 24 pesticide residue data of 6 kinds of fresh edible vegetables, which belonged to the provincial routine detection from 2008 to 2011 in Pingliang City of Gansu Province. The acute dietary risk assessment calculation method of JMPR was used to conduct acute dietary risk assessment. The risk probability of fenpropathrin and omethoate in cucumber was 0.2069, 0.0143; the risk probability of fenpropathrin in tomato was 0.0714; the risk probability of dichlorvos and fenpropathrin in Chinese cabbage was 0.0417; the risk probability of dichlorvos, acephate, fenpropathrin in cabbage were 0.0930, 0.0385, 0.0370;the risk probability of fenpropathrin in green peppers was 0.0217;the risk probability of dichlorvos in long pepper was 0.0526. The 4 kinds of pesticides which contained fenpropathrin, omethoate, dichlorvos, acephate had acute dietary risk, else had no acute dietary risk.
