目的了解陕西省近3年蔬菜水果中氨基甲酸酯农药残留情况。方法2004—2006年对陕西省6个地市采用随机与定点抽样的方法采集市售蔬菜水果16个品种样品,在严格的质量控制下,通过高效液相色谱法测定氨基甲酸酯残留量。结果2004年样品氨基甲酸酯总检出率为4.60%,其中蔬菜样品检出率为0.00%,水果检出率为25.00%。2005年样品氨基甲酸酯总检出率5.69%,其中蔬菜样品检出率为4.06%,水果样品检出率为17.14%;2006年样品氨基甲酸酯总检出率9.06%,其中蔬菜样品检出率9.31%,水果样品检出率为5.55%。结论该省蔬菜水果中氨基甲酸酯农药残留现状较为安全,但有逐年升高的趋势,且检出国家禁用的农药品种,应加强农药使用的监管,保证农产品安全。
Objective To understand the residues of carbamate pesticides in fruits and vegetables of Shaanxi Province in recent 3 years. Methods From 2004 to 2006, 16 varieties of vegetables and fruits were collected by random sampling and spot sampling from 6 cities in Shaanxi Province. The residual quantity of carbamate was determined by high performance liquid chromatography under the strict quality control. Results The total detection rate of carbamate samples was 4.60% in 2004, of which the detection rate of vegetable samples was 0.00% and the detection rate of fruits was 25.00%. In 2005, the total carbamate detection rate was 5.69%. The detection rate of vegetable samples was 4.06% and the detection rate of fruit samples was 17.14%. In 2006, the total carbamate detection rate was 9.06% The detection rate was 9.31%, and the detection rate of fruit samples was 5.55%. Conclusion The status of carbamate pesticide residues in vegetables and fruits in the province is relatively safe, but there is a trend of increasing year by year. The detection of banned pesticide varieties in the province should be strengthened and the use of pesticides should be strengthened to ensure the safety of agricultural products.
