Determination of 22 Neonicotinoid Pesticides and Their Metabolites in Urine Samples by HPLC-MS/MS Combined with Liquid-Liquid Extraction
An analytical method based on high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS) was established for the simultaneous detection of 22 neonicotinoid pesticides(NEOs) and their metabolites in human urine. Urine was extracted by liquid-liquid extraction after enzymatic hydrolysis,pH adjusted by formic acid,and then separated by HSS T3 column. Gradient elution was performed with (0.1% formic acid+5 mmol/L ammonium formate)/water-acetonitrile as mobile phase. The samples were scanned simultaneously in positive/negative ion mode,detected in multiple reaction monitoring(MRM) mode,and quantized by internal standard method. The results showed that there was a good linear relationship between the 22 NEOs and their metabolites in the mass concentration ranges(

0.995 0). The detection limit and quantitation limit of the method were 0.05-0.10 ng/mL and 0.15-0.30 ng/mL,respectively. The average recoveries were 64.5%-125% at low,middle and high spiked levels. The relative standard deviations ranged f
rom 0.10% to 12%. In addition,sample stability tests indicated that urine samples should be tested as soon as possible after collection. The method had been used to determine 54 real urine samples. All samples were detected NEOs or their metabolites. The established method is efficient and stable,and can simultaneously detect 22 NEOs and their metabolites.
