Simultaneous monitoring of five benzimidazole fungicides in soil by UPLC-MS
A method for simultaneous monitoring of five benzimidazole fungicides in soil by QuEChERS-ultra-high performance liquid chromatography and mass spectrometry was developed.The five benzomidazole fungicides had good linearity in the range of 5.00~400μg·L-1 with correlation coefficients greater than 0.9990.The detection limits were 0.03~0.11 μg·kg-1,and the recoveries ranged from 87.4%to 104.5%with relative standard deviations less than 5%for the three concentration levels.The method has the advantages of simple and rapid pretreatment,low consumption of organic reagents,high sensitivity,accurate and reliable test results,and is suitable for simultaneous analysis of 5 benzimidazole fungicides in soil.
