Simultaneous determination and risk assessment of fipronil and its metabolites in sugarcane, using GC-ECD and confirmation by GC-MS/MS

A sensitive gas chromatographic method using a modified QuEChERS technique is reported for simultaneous determination, dissipation and risk assessment of fipronil and its metabolites in sugarcane and soil. Recoveries were 80.7–98.5% with precision within 1.4–16.5% estimated at the limits of detection (LOD) 0.0015–0.002 µg g−1 and limits of quantification (LOQ) 0.005 µg g−1. Fipronil dissipated with half-life (T1/2) of 2.8–4.3 days while for...
