Abstract：In order to evaluate the pesticide residue status in leek from Shanxi Province，and dietary intake risk for residents，this study carried out accurate quantification on 13 kinds of pesticide residue in 121 leek samples collected from 6 different leek main producing areas by using GC-MS/MS and UPLC-MS/MS technology．And then，risk assessment was conducted on pesticide residue detected in the samples by index of food safety（IFS） method and hazard risk coefficient method．Results showed that the pesticide detection rate of leek samples was 97.5%，and pesticide residue excess rate was 32.2%，among which procymidone was the main pesticide causing excessive pesticide residue in leeks．Besides，3 pesticides prohibited in using for vegetables，namely：phorate，chlorpyrifos and carbofuran were detected．The detection rate of pesticide multi-residue was 57.0%．Besides，there were differences in kinds and quantities of pesticide residue in leeks，sampling times，planting regions and cultivation patterns．Results of IFS method assessment indicated that the IFS value of 12 kinds detected pesticides were all less than 1，meaning their dietary intake risk was acceptable．While，results of hazard risk coefficient method evaluation indicated that procymidone，phorate，chlopyrifos，carbofuran，pendimethalin，cyhalothrin were 6 high risk pesticides．In short，the quality safety risk of leek produced in Shanxi is within an acceptable range．But use of high risk pesticide is still existing．Work of supervising on leek quality and safety is needed to be further strengthened．
