Title: Determination of five organophosphorus pesticides in tea by gas chromatography with mass-selective detection
Abstract: Interval time was shortened through simplifying extraction procedure.Quality and quantitative analysis of five organophosphorus pesticides were determined by GC/MS in SIM mode.The results showed that average recovery of five pesticide at the concentration of 1.0 mg/kg was in a range of 86.5%~101.5%,and coefficient of variation was 4.8%~9.0%.The minimum detection limit for tea was between 0.0047 mg/kg and 0.0023 mg/kg.Those all suggest that the results meet the fundamental requirements for pesticide residue analysis and the method is accurate and reliable.
