摘要
为了解贵州省蔬菜中有机磷农药残留现状,2006~2012年,采用色谱法,对该省9个市(地、州)无公害蔬菜生产基地、农贸市场、超市、蔬菜批发市场等地抽取的各类蔬菜4000余个样品中的有机磷农药残留进行测定。结果表明:2006—2012年贵州省有机磷类农药残留超标率由8.51%下降到1.12%,总体呈下降趋势,蔬菜农药残留情况逐年好转;蔬菜农药残留检出率、超标率呈逐年下降趋势;农药检出种类从高毒、禁用农药向低毒的毒死蜱、三唑磷等农药转变;白菜类、绿叶菜类蔬菜农药残留超标率较最高,豆类蔬菜和瓜类蔬菜农药残留率较低。针对贵州省蔬菜有机磷农药残留现状做了初步分析,并提出了相应的建议措施。
In order to investigate organophosphorus pesticide residue in vegetables, GC - MS was employed to determine the organophosphorus pesticide residues in more than 4000 vegetable samples gathered from pollution-free vegetable producing bases, open markets, supermarkets, wholesale markets and so on. The results showed the pesticide residue over standard rate decreased from 8.51% to 1.12% during 2006 and 2012, which was on a declining curve, indicating a pesticide residue was improved year by year. The relevance ratio and pesticide residue over standard in vegetables were on a declining curve ; and the kinds of pesticide transferred from high- toxic pesticide, forbidden pesticides to low-toxic pesticides, such as Dursban, triazophos; The over standard rate saw a most highest in cabbages and green-leave-vegetables, the pesticide over standard rate in tegume vegetables and melon vegetables were lower. Preliminary analysis of the current situation of pesticide residue in vegetables in Guizhou province was made, and relevant proposes was arose.
