  • A method for simultaneous detection of 13 sulfonamides drugs in seawater by using ultra performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) was established and optimized, and used for analysis of the surface seawater samples collected from Dongzhai Harbour, Hainan. The results show that in case of the peak types of sulfonamides in the chromatogram are better and the correlation coefficient of the standard curve is high(R2 ≥ 0.996) when the sulfaonamides in the sea water were determined by using UPLC-MS/MS with mobile phase A: methanol-acetonitrile(V∶V=1∶1) and mobile phase B: 0.1% formic acid-10 mM ammonium acetate as the mobile phase and the initial mobile phase(5% mobile phase A and 95% mobile phase B) as the reconstituted solvent. Thirteen sulfonamides were separated well in 14 minutes and trheir recovery rates were from 70.4 to 103%, with a relative standard deviation(RSD) of between 1.2% and 12.8%. This method had high sensitivity and good reproducibility, and is suitable for simultaneous detection of sulfonamides in seawater. At the same time, five sulfonamides were detected in the water samples of the Dongzhai Harbour. The detection rates were from 60% to 100%. The highest detection frequency of sulfamethoxazole(SMX) was 100%, sulfameter(SME) and sulfachloropyridazine(SCP) had high detection rates(around 70%) in the Dongzhai Harbor, and the other two detected were sulfamethazine(SMA) and sulfadiazine(SDZ). The highest concentration of sulfonamides detected was up to 3.35 ng·L-1. Compared with other areas, the concentrations of sulfonamides detected in Dongzhai Harbor was at a relatively low level.
