【Abstract】 This paper describes a method for quick determination of some pesticides residue in the soil. Analysis is performed by gas-chromatography with Mass selective detection and selected ion monitoring (GC-MS-SIM). Pesticides residue are positively confirmed by retention times (RT) and ion ratios.The fortified recovery is between 83.0%-112.0%, the coefficient of variability is between 4.8%～15.2%.更多还原
