Title: Determination of Organophosphorus and Carbamate Pesticide Residues in Soil by Gas Chromatography-Mass Spectrometry
Abstract: A method for determination of organophosphorus and carbamate pesticide residues in soil was established by GC-MS.With acetone and petroleum ether(4∶1,V/V) as extraction solvent,pesticide residues in soil were extracted ultrasonically.The extracts were then cleaned up with Florisil column prior to the subsequent analysis by GC-MS.The recoveries obtained from samples spiked with standards at the concentration levels of 0.1 μg/mL and 0.5 μg/mL were in the ranges of 70.1%~119.0% and(78.1%~119.1%) with relative standard deviations of 6.30%~9.80% and 5.20%~8.23%,respectively.With selected ion monitoring,the qualitative and quantitative analysis were carried out by retention times and characteristic ions.
