13 pollutants in surface water including Microcystin-LR were determined using ultra high pressure liquid chromatography tandem mass spectrometry method (UPLC-MS/MS).The determination condition was op-timized so that all the target compounds could be detected within 3 minutes.The results indicated that:all of the calibration curves showed good linear relationship with a correlation coefficient above 0.99.The determination limits of the targets were from 0.12 μg/L to 8.40 μg/L and the recovery rates of practical surface water samples were between 62.0% and 104%.6 parallel samples were determined,and the relative standard deviations (RS-Ds)were between 1 .8% and 5 .7%.When determining the practical water samples using this method,only at-razine and malathion were detected,with a mass concentration of 0.6 μg/L and 0.7 μg/L,respectively.
