Abstract:A method was developed for the determination of 9 thiocarbamate pesticide residues in rice by HPLC-MS/MS. The proposed methods showed a good linearity in the range of 1.0~100 ?g/L with the linear correlation coefficients of 0.9966~0.9993 and LOQs of lower than 0.5?g/L. The average recoveries for the pesticides ranged from 76.0% to 120.0%, with the relative standard deviations (RSDs) were less than 19.6% for all compounds. The method was simple and practical，rapid and accurate with low detection limit. The research on food safety and risk early warning had certain reference significance.
