    青海省乐都区某镇大棚蔬菜中四类农药的残留现况与意义

    Evaluation on Four Kinds of Pesticide Residuesin Greenhouse Vegetable in Ledu City of Qinghai Province

      摘要
    • 摘要:
      目的 研究青海省乐都区某镇大棚蔬菜中四大类农药（有机磷类、有机氯类、氨基甲酸酯类、菊酯类）的残留现况与意义。
      方法 采用梅花形布点方式抽取大棚蔬菜样品35份，利用气相色谱-质谱法进行农药的残留量检测。
      结果 四大类农药中氨基甲酸酯类农药检出率最高，大棚蔬菜中有机磷、有机氯、氨基甲酸酯类、菊酯类农药检出率最高的分别是杀扑磷（54.29%）、三氯杀螨醇（57.14%）、灭多威（40.00%）、高效氟氯氰菊酯（71.43%）。
      结论 大棚蔬菜中4类农药均检出，氨基甲酸酯类农药检出率最高。种植者对农药残留危害性的认识不足，应加大宣传力度，注重个人防护措施，要大力推广高效、低毒、不污染环境的生物农药。

       

      Abstract:
      Objectives To investigate the residue of four kinds of pesticide (organic phosphorus, organic chlorine, carbamate and pyrethroid) in greenhouse vegetable in Ledu district, Qinghai province.
      Methods Thirty five greenhouse vegetable samples were collected by plum blossom method, and the pesticide residues were determined by gas chromatography-mass spectrometry.
      Results The detection rate of carbamate was the highest among four pesticides. The highest detection rates for organophosphorus, organochlorine, carbamate and pyrethroid pesticides in greenhouse vegetables were Ketopril (54.29%), DDT (42.86%), methomyl (40.00%) and cyhalothrin (71.43%) respectively.
      Conclusions The residues of four kinds of pesticides were detected in greenhouse vegetable, and the detection rate of carbamate pesticide was the highest. The knowledge on the harm of pesticide residues was insufficient in farmers, and it should be strengthened. The personal protective measures should be emphasized. Biological pesticides with high efficiency, low toxicity and pollution-free to environment should be promoted.
