摘要: 采用高效液相色谱—串联质谱(HPLC\|MS/MS)技术,对上海市521例市售果蔬样品进行检测,并将检测数据与国家标准GB2763—2014、欧盟和日本的农药残留最大限量(MRLs)进行比对分析,从而全面评估上海地区农产品中的农药残留情况。结果表明,共有17种农药在本次调查中被检出,其中941%为中低毒农药,农药检出总频次481次,说明上海地区市售果蔬中还是存在着一定的农药残留现象,但得到了有效的控制,农药残留安全程度达983%。但与欧盟和日本的最大残留限量标准相比,我国仍存在一定差距,有关部门仍需加强对农产品农药残留的监控和标准细化,更好地保障农产品的质量安全。

Abstract: In order to carry out an overall assessment of pesticide residues of agricultural products in Shanghai, the 521 samples including commercially available fruits and vegetables were detected by high performance liquid chromatography\|tandem mass spectrometry (HPLC\|MS/MS), and the measured data was compared with the maximum residue limits (MRLs) of GB2763\|2014, European Union and Japan, respectively. The results showed that 17 kinds of pesticides were detected, among them 941% were of moderate and low toxicity. The total frequency of pesticides detected was 481 times in this survey. The pesticide residues of agricultural products in Shanghai were generally under control, 983% of commercially available fruits and vegetables were safe. However, compared with the MRLs of European Union and Japan, there is still a gap in China at present, so the standard refinement and the monitoring of pesticide residues should be reinforced to further reduce risk level and ensure the safety of agricultural products.
