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. |
