    山西省杏中农药残留水平及管控建议

    Pesticide residue and governance recommendations of apricot in Shanxi Province

    • 摘要: 为评估山西省杏中的农药残留水平,建立超高效液相色谱-串联质谱(UPLC-MS/MS)测定杏中吡虫啉、苯醚甲环唑等29种农药的分析方法,并对杏中的残留量进行分析。结果表明:29种农药在0.001~0.2 mg/kg范围内线性关系良好,决定系数R2 > 0.99;在0.005、0.1和1 mg/kg 3个添加水平下,平均回收率为63%~117%,相对标准偏差(RSD)为0.7%~7.7%;定量限(LOQ)为0.005 mg/kg,符合农药多残留分析要求。采用所建立的方法对山西省采集的42个杏样品进行分析,结果表明:42个杏样品中有26个检出农药,检出率为61.9%,其中吡虫啉检出率最高(45.2%);样品检出残留量在< 0.005~0.57 mg/kg之间。共检出13种农药,在杏上均未登记,表明作为一种特色小宗作物,杏中病虫害防治存在无药可用和无标可依等问题,影响农产品安全。通过对比国内外杏中有关农药残留限量标准建设情况,建议我国相关部门加强监管,对氰霜唑、氟环唑、乙螨唑、多效唑和哒螨灵5种农药进一步考察制定其残留限量的必要性和可行性。

       

      Abstract: In order to evaluate the pesticide residue levels in apricots in Shanxi Province, an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was established for the determination of 29 pesticides such as imidacloprid and difenoconazole in apricots, and the pesticide residues in apricot samples were analyzed. The results showed that the linearity of 29 pesticides were acceptable in the range of 0.001~0.2 mg/kg with R2 > 0.99. The average recoveries ranged from 63% to 117% with the relative standard deviation (RSD) of 0.7% to 7.7% at the spiked levels of 0.005, 0.1 and 1 mg/kg, and the limit of quantification (LOQ) was 0.005 mg/kg, which met the requirements of pesticide multi-residue analysis. The established method was used to analyze 42 apricot samples collected in Shanxi Province, and the results showed that the pesticides were detected in 26 of the 42 apricot samples, with a detection rate of 61.9%. Imidacloprid had the highest detection rate (45.2%), and the residue levels ranged from < 0.005~0.57 mg/kg. A total of 13 pesticides were detected, none of which were registered on apricots, indicating that as a distinctive minor crop, there are problems in the pests control of apricot, such as the lack of pesticides available and no standards to follow, which affected the safety of agricultural products. By comparing the current status of pesticide residue limit standards in apricot in China with that in other countries, it is suggested that the pesticide residue supervision should be strengthened in China, and the necessity and feasibility of the establishment of MRL of five pesticides, namely cyazofamid, epoxiconazole, etoxazole, paclobutrazol and pyridaben, in apricot should be further investigated.
