	abstract = {A method for simultaneous measure of nine neonicotinoid insecticide residues in soil was developed by using liquid chromatography-tandem mass spectrometry (LC-MS/MS) coupled with a quick pretreatment procedure. The soil was extracted with a mixture of acetonitrile and dichloromethane (1:2, v:v) and cleaned up with Primary Secondary Amine (PSA). Matrix-matched standards were prepared to eliminate the interference of the matrix. The LC{\textendash}MS/MS conditions were optimized to separate the nine neonicotinoids within 6.7 min, and the obtained limits of detection (LODs) and limits of quantification (LOQs) ranged from 0.01 to 0.84 ng g-1 and 0.05{\textendash}2.79 ng g-1, respectively. Recoveries of the studied neonicotinoids (except for nitenpyram) ranged from 79.41 to 100.20\% with relative standard deviations (RSDs) less than 10\% at spiked levels of 5 ng mL-1, 100 ng mL-1 and 500 ng mL-1, and RSDs for the interday and intraday method repeatability were less than 9\%. The method was applied to measure neonicotinoid residues in soil samples collected from parks (n = 35) and residential areas (n = 33) in Tianjin, China. Seven neonicotinoids were detected, with imidacloprid being the most frequently detected one, followed by acetamiprid and thiamethoxam. The total concentrations of neonicotinoids in soil ranged from 0.27 to 230.76 ng g-1 in parks and 0.23{\textendash}132.66 ng g-1 in residential areas. {\textcopyright} 2018 Elsevier B.V.},
