采用超高效液相色谱-串联质谱联用仪和气相色谱-串联质谱联用仪对湖北省宜昌市区、丹江口市、秭归县和兴山县的柑橘(Citrus reticulata Blanco)样品农药残留情况进行定量检测和分析。结果表明,柑橘样品农药残留的检出率高达91.9%,其中,禁用农药检出率为1.6%;限用农药检出率为9.5%;允许使用农药检出率为68.3%;未登记使用农药检出率为15.9%。农药使用情况较为普遍,不过由于禁、限用农药控制程度较好,因此柑橘质量整体安全性较高。
The residues of pesticides in Citrus reticulata Blanco samples of Yichang, Danjiangkou, Zigui and Xingshan were determined by using ultra performance liquid chromatography-tandem mass spectrometry and gas chromatography-tandem mass spectrometry. Detection and analysis. The results showed that the detection rate of pesticide residues in citrus samples was as high as 91.9%, among which the detection rate of banned pesticides was 1.6%; the detection limit of pesticides was 9.5%; the detection rate of pesticides allowed was 68.3%; the unregistered pesticides The detection rate was 15.9%. The use of pesticides is more common, but due to ban, restricted pesticide control is better, so the overall quality of citrus higher security.
