目的为了了解应城市水产品及其生长环境中农药残留现状,为政府部门制定有关政策提供依据。方法2007年4月—2008年7月在辖区内采集了农产品及其生长环境中样品10类622份,依据国标方法进行了4类21种农药残留含量检测。结果样品农药残留检出率为19.61%,超标率8.68%;检出率高低依次为猪肉>大米>一般蔬菜>茶叶>鱼>菜油>土壤>地表水>井水和莲藕;同一品种样品农药残留含量差别较大,不同品种样品农药残留差异有统计学意义(χ2=130.25,P<0.01);不同农产品种植规模相关样品农药残留差异亦有统计学意义(χ2=225.80,P<0.01),农药残留含量与其生产过程中的用药监管有关。结论应城市农产品农药残留情况比较严重提示绿色农产品的生产需要规模化以及科学严格的监管。
Objectives To understand the status quo of pesticide residues in aquatic products and their growing environment in Yingcheng and provide the basis for government departments to formulate relevant policies. Methods From April 2007 to July 2008, 622 species of 10 kinds of agricultural products and their environment were collected from the area under its jurisdiction. The content of 21 kinds of pesticides in 4 classes was detected according to the national standard method. Results The detection rate of pesticide residues in samples was 19.61% and the excessive rate was 8.68%. The detection rates were: pork> rice> vegetables> tea> fish> vegetable oil> soil> surface water> well water and lotus root; (Χ2 = 130.25, P <0.01). There were also significant differences in pesticide residues between the samples of different scales of agricultural products (χ2 = 225.80, P <0.01), and the contents of pesticide residues in different samples were significantly different Residues and its production process of drug regulation. Conclusion The situation of pesticide residues in agricultural products in Yingcheng should be more serious, suggesting that the production of green agricultural products needs to be scaled up and scientifically regulated.
