| Abstract: |
| A gas chromatography-positive chemical ionization mass spectrometric（GC-PCI/MS） method was developed for the determination of migration levels of 7 N-nitrosamines and N-nitrosatable substances including N-nitrosodimethylamine（NDMA），N-nitrosodiethylamine（NDEA），N-nitrosodi n propylamine（NDPA），N-nitrosodi n butylamine（NDBA），N-nitrosopiperidine（NPIP），N-nitrosopyrrolidine（NPYR） and N-nitrosomorpholine（NMOR） from household rubber gloves by using Sep Pak AC2 connecting to Sep Pak Dry cartridges.The developed method was simple，rapid，sensitive and accurate.Its quantitation limits for N-nitrosamines and N-nitrosatable substances were 1.25 μg/kg and 5.0 μg/kg，respectively.The total release values for the 7 N-nitrosatable substances were 6.96-168.46 μg/kg,in which NDEA，NDMA and NDBA were found most frequently in 13 analysed household rubber gloves.The risk exposure levels of seven N nitrosamines from household rubber gloves were in the class of 1.81-43.80 μg per person in a year，which would bring a potential risk to people，especailly to some occupational population. |
