目的了解青岛市市售蔬菜农药残留状况,发现食品安全隐患,为进一步制定和采取有效预防控制措施提供理论依据。方法于2010—2011年间,在青岛市调查网点抽取蔬菜样品5 228份,依据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类农药多残留的测定》对样品进行检测,依据GB 2763—2014《食品中农药最大残留限量》对38种农药进行判定。结果农药残留检出率为24.77%,总不合格率为15.57%;各类蔬菜中以葱蒜类蔬菜农药检出率和不合格率最高,其次为绿菜类蔬菜,各类农药不合格率排序为:拟除虫菊酯类农药>有机磷农药>有机氯农药>氨基甲酸酯类农药,其中主要的不合格农药为氯氰菊酯(3.18%)、百菌清(2.54%)、毒死蜱(2.16%)和克百威(1.80%);混合农药检出率为5.87%,占检出样品的23.71%,不合格率高达4.65%。第四季度蔬菜农药残留检出率和不合格率最高,分别为42.05%和20.62%。结论青岛市市售蔬菜农药残留状况整体良好,但仍存在一些问题,应采取有效措施加强蔬菜的监督管理,确保市民使用蔬菜的安全。
Objective To understand the status of vegetable pesticide residue on the market of Qingdao City and find out the hidden dangers of food safety and to provide a theoretical basis for further formulation and effective prevention and control measures. Methods During the period of 2010-2011, 5 228 vegetable samples were collected from the survey sites in Qingdao.

The detection rate and the unqualified rate of pesticides in onion and garlic vegetables were the highest in all kinds of vegetables, followed by the vegetables in green vegetables and the unqualified rate of various pesticides The order of the pesticides is pyrethroid pesticides, organophosphorus pesticides, organochlorine pesticides, and carbamate pesticides. The main unqualified pesticides are cypermethrin (3.18%), chlorothalonil (2.54%), chlorpyrifos (1.80%). The detection rate of mixed pesticides was 5.87%, accounting for 23.71% of the detected samples with the failure rate as high as 4.65%. The fourth quarter, the highest rate of pesticide residues in vegetables and unqualified rate, respectively 42.05% and 20.62%.
