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.

Key words: high performance liquid chromatography\, tandem mass spectrometry, pesticide residues, maximum residue limits
