目的了解遂宁市蔬菜中农药残留情况,为政府部门制定农药问题相关措施提供科学依据。方法于2011年-2013年从遂宁市5个区县农贸市场和超市采集136份蔬菜样品。采用NY/T 761-2008《蔬菜和水果中有机磷、有机氯、拟除虫菊酯和氨基甲酸酯农药多残留的检测》进行农药的残留检测,检测结果依据GB 2763-2014《食品中农药最大残留限量》进行判定。结果 136份蔬菜的农残检出率和超标率分别为54.4%和13.2%,不同类别的蔬菜均有超标。超标率最高的蔬菜为叶菜类(20.0%),超标率最高的农药种类为有机磷类(11.0%)。不同年份,不同种类农药检出率和超标率差异均有统计学意义(P<0.05),不同种类蔬菜的超标率差异无统计学意义(P>0.05)。结论遂宁市蔬菜中农药使用普遍,叶菜类蔬菜农药残留较为严重,应加强种植和销售环节的监管,降低农药残留对人体的危害。
Objective To understand the pesticide residues in vegetables in Suining City and provide scientific basis for the government departments to formulate pesticide problems. Methods From 2011 to 2013, 136 vegetable samples were collected from 5 markets and supermarkets in Suining City. The residues of pesticides were detected by the NY / T 761-2008 “Detection of Organophosphorus, Organochlorine, Pyrethroid and Carbamate Pesticide Residues in Vegetables and Fruits”. The test results were based on GB 2763-2014 “The Maximum Pesticide in Food Residual limit ”to determine. Results The detection rate of pesticide residues and the rate of over-standard pesticide residues in 136 vegetables were 54.4% and 13.2%, respectively. All kinds of vegetables exceeded the standard. Vegetables with the highest rates of over-standard were leafy vegetables (20.0%), and those with the highest rates of over-standard pesticides were organic phosphorus (11.0%). In different years, the differences of the detection rates of different types of pesticides and the exceeding rate were statistically significant (P <0.05), and there was no significant difference between the different types of vegetables (P> 0.05). Conclusion Suining vegetables commonly used in vegetables, pesticide residues in leafy vegetables is more serious, should strengthen the supervision of planting and marketing links to reduce the harm of pesticide residues on the human body.
