A selective gas chromatography tandem triple quadrupole mass spectrometry was used to detect nine volatile nitrosamines,including N-nitrosodimethylamine(NDMA),N-nitrosodiethylamine(NDEA),N-nitrosomethylethylamine(NMEA),N-nitrosodipropylamine(NDPA),N-nitrosopyrrolidine(NPYR),N-nitrosopiperidine(NPIP),N-nitrosodibutylamine(NDBA),N-nitrosomorpholine(NMOR),N-nitrosodiphenylamine(NDPhA) in local sausage on sale by using QuEChERS sample pretreatment.The calibration curves of nine volatile nitrosamines were linear in the range of 0.25-200 μg/L,with detection limits of 0.01-0.10 μg/kg.The recoveries were in the range of 90.7%-116.0% at three spiked concentration levels in sample,with relative standard deviations(RSDs) of 1.8%-14.0%.The method was applied in the detection of local sausage on sale,and seven volatile nitrosamines were all detected.The detection rates of NDMA，NMOR，NPYR，NDPA were higher than that of the others.The contents of total volatile nitrosamines were in the range of 1.85-13.44 μg/kg.The developed method was simple,rapid,sensitive and accurate.
