    银川市郊大棚蔬菜中有机磷农药残留现状调查

    Current Status of Organophosphorus Pesticide Residues in Vegetables Grown in Greenhouse in Yinchuan Suburb

    • 摘要:
      目的 了解银川市郊大棚蔬菜中有机磷农药残留状况。
      方法 在宁夏银川市兴庆区某镇随机抽取35座蔬菜大棚, 用气相色谱法对棚内蔬菜中20种有机磷农药残留进行检测。
      结果 蔬菜样品中有10种有机磷农药检出, 总体检出率为40%, 合格率为85.71%。大棚芹菜中有机磷农药残留检出率50%, 高于西红柿和黄瓜, 大棚蔬菜中农业部推荐替代使用的有机磷农药检出率34.3%, 高于蔬菜中禁用有机磷农药检出率8.6%, P=0.029, P < 0.05, 差异具有统计学意义, 三唑磷最大超标倍数达41.86倍。
      结论 银川市郊大棚蔬菜中存在有机磷农药残留, 不同种类大棚蔬菜及不同种类有机磷农药残留情况不同, 应加强对农药相关知识的宣传, 对种植者进行合理的施药指导, 尽可能降低农药使用对食品及环境安全造成的危害。

       

      Abstract:
      Objectives To investigate the content of organphosphorus pesticide residues in vegetables grown in greenhouse in Yinchuan suburb.
      Methods Vegetable samples were randomly selected from 35 greenhouses in a certain town in Yinchuan suburb and 20 kinds of organophosphorus pesticide residues in vegetables were determined.
      Results Ten kinds of organophosphorus pesticides were detected from samples, and the overall detection rate was 40%, with a pass rate of 85.71%. The detection rate for celery was 50%, which was higher than that in tomatoes and cucumbers. The detection rate for organophosphorus pesticides recommended by the Ministry of Agriculture was 34.3%, which was higher than 8.6% for banned organophosphorus pesticides (P < 0.05). The content of triazophos residues in vegetable samples exceeded the maximum limits for 41.86 times.
      Conclusions There were certain amounts of organophosphorus pesticide residues in vegetables grown in greenhouses in Yinchuan suburb. The situation of residues was different in the type of greenhouses and organophosphorus pesticides. Several samples was detected with a variety of organphosphorus pesticide residues. Therefore, strengthening the publicity of pesticide-related knowledge, giving reasonable guidance to growers on pesticide-spraying and trying our best to minimize the hazards on food and environment caused by pesticides.
