Determination and Dissipation of Fipronil and Its Metabolites in Peanut and Soil

In this study, a modified quick, easy, cheap, effective, rugged, and safe (QuEChERS) method was established for the extraction and cleanup of fipronil and its three metabolites (fipronil solfone, sulfide, and desulfinyl) in peanut kernel, shell, straw, seedling, and soil samples, and liquid chromato...

Zusammenfassung:	In this study, a modified quick, easy, cheap, effective, rugged, and safe (QuEChERS) method was established for the extraction and cleanup of fipronil and its three metabolites (fipronil solfone, sulfide, and desulfinyl) in peanut kernel, shell, straw, seedling, and soil samples, and liquid chromatography–tandem mass spectrometry (LC-MS/MS) was used for analysis. The average recoveries were 66–116% at the level of 0.001–0.1 mg/kg with the RSD
