摘要
目的:了解镇海区不同季节不同蔬菜中农药残留情况,为确保蔬菜食用安全提供监管依据。方法:通过对镇海区蔬菜生产基地和散户生产和镇海各菜场中销售的叶菜类、果菜类、茎菜类、根菜类、花菜类等的农药残留量按季节进行抽样,用气相色谱法对14种有机磷农药和6种拟除虫菊酯类农药进行检测。结果:抽查样本中农药残留量检出率为7.85%,残留量超标率为3.78%。其中蔬菜生产基地农药残留量检出率为3.27%,超标率为0.65%,显著低于散户和菜场中蔬菜的检出率(分别为8.20%和11.54%)和超标率(分别为4.92%和6.92%)。在20种检测的农药中,毒死蜱和氯氰菊酯的检出率明显高于其它农药。叶菜类的检出率为11.34%,超标率为8.24%,明显高于其他品种的蔬菜。从时间上看,农药残留并无明显的季节变化。结论:应采取有效措施,加强蔬菜的监督管理,从源头禁止高毒农药的使用,加大蔬菜种植、销售环节的监测,确保市民食用蔬菜的安全。
Objective：To investigate the conditions of pesticide residues in different seasons in Zhenhai district in order to provide inspection basis for assuring the safety of vegetable intake.Methods： In 2010 year,344 samples of vegetables were randomly collected from vegetable production base,production of vegetables around the famers and vegetables market in Zhenhai district.The vegetables were random sampling in accordance with leafy vegetables,stem vegetables,root vegetables,cauliflower classes and fruit vegetables categories in different seasons,and measured 14 organophosphorus pesticides and 6 pyrethriod pesticides by GC.Results： The detection rate of pesticide residues in all vegetables was 7.85%,and over-standard rate was 3.78%.The detection rate of Vegetable Production Base was 3.27%,which was lower than famers（8.20%） and vegetable market（11.54%）,and over-standard rate was 0.65% which also was lower than famers（4.92%） and vegetable market（6.92%）.In 20 kinds of pesticides,the detection rate of chlorpyrifos and cypermethrin was higher than other pesticides.The detection rate of leafy vegetables was 11.34%,and over-standard rate was 8.24% which is higher than other vegetables categories.There was no significant difference among different seasons in our research.Conclusion： In order to assuring the safety of vegetable intake,the effective measures should be taken.It is necessary that the inspection and administration should be strengthened,and the use of high toxic pesticides should be prevented from the source,and the monitoring on vegetables between planting and sale links should be enlarged.
