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。
In order to carry out an overall assessment of pesticide residues of agricultural products in Shanghai,the521 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.
