title: [Determination of four organophosphorus pesticides and their metabolites in vegetables using solid-phase extraction coupled with liquid chromatography tandem mass spectrometry].
abstract: metabolites were 76.9%- 102.8%, the precision ranged from 5.92% to 10. 19%, the limits of quantification ranged from 0. 001 to 0. 01 mg/L, and the linear correlation coefficients were 0. 998 2-0. 999 9 in the range of 0. 01 -1. 00 mg/L. This method was applied in the analysis of Chinese cabbages, hot peppers, tomatoes and onions from markets. This method can be applied in rapid detection of the organophosphorus pesticides and their metabolites in vegetables. metabolites were 76.9%-102.8%, the precision ranged from 5.92% to 10.19%, the limits of quantification ranged from 0.001 to 0.01 mg/L, and the linear correlation coefficients were 0.9982-0.9999 in the range of 0.01-1.00 mg/L.
