目的了解绵阳市2012年市售蔬菜中农药残留情况,为食用蔬菜监管提供依据。方法全部样品均按照GB/T 5009-2003的方法进行农药的残留检测。依据GB 2763-2005《食品中农药最大残留限量》进行判定。结果 2012年共检测蔬菜165份,农药检出率和超标率分别为72.12%和23.64%。豆类、根茎类、叶菜类、瓜果菜类和食用菌类蔬菜检测农药残留超标率分别为8.00%、23.53%、36.00%、5.26%和27.03%,差异有统计学意义(χ2=11.41,P<0.01)。不同种类农药超标率差异有统计学意义(χ2=62.42,P<0.01)。夏季和冬季蔬菜农药超标率差异无统计学意义(χ2=3.44,P>0.05)。结论绵阳市叶菜类蔬菜中农药残留情况较为严重,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。

Results A total of 165 vegetables were detected in 2012. The detection rates and the over-standard rates of pesticides were 72.12% and 23.64% respectively. Pesticide residue exceeded standard rates of 8.00%, 23.53%, 36.00%, 5.26% and 27.03% in legumes, rhizomes, leafy vegetables, fruits and vegetables and edible fungus vegetables respectively, the difference was statistically significant (χ2 = 11.41 , P <0.01). There were significant differences in the over-standard rates of different types of pesticides (χ2 = 62.42, P <0.01). There was no significant difference between summer and winter vegetable pesticide excess (χ2 = 3.44, P> 0.05). Conclusion The pesticide residues in leafy vegetables in Mianyang City are more serious. Effective measures should be taken to strengthen the supervision and management of vegetables, prohibit the use of highly toxic pesticides from the source and increase the monitoring of planting and sales of vegetables so as to ensure the safety of vegetables consumed by the public .
