    Abstract: Quick and high efficient multiresidue analysis method is critical for screening and moniotring of the pesticide residue in soil. In this study, a high throughput multiresidue method was developed based on QuEChERS sample preparation method combined with gas chromatography-triple quadrupole mass spectrometry. The extraction and clean-up procedures and parameters including extraction method, extraction time, buffer system, and clean-up adsorbent selection were thoroughly investigated and optimized. Most coefficients of determination (r2) were higher than 0.99 within the calibration linearity range of 2-200 μg·L-1. Most recoveries at six spiking levels were in the range of 70%-120% with RSDs <20% indicating satisfactory accuracy. The limits of quantification (LOQ) for the pesticides were determined based on recovery and accuracy results and ranged from 2 to 20 μg·kg-1, and for 78.4% of the pesticides the LOQs were 2 μg·kg-1. Finally, the proposed method was used in real sample analysis. This method was proved to be simple, sensitive and effective, which can be applied for large-scale pesticide screening and quantification in soils.
