该文用Sep Pak AC2串联Sep Pak Dry cartridges固相萃取小柱对家用橡胶手套迁移提取液中的N-亚硝基二甲胺(NDMA)、N-亚硝基二乙胺(NDEA)、N-亚硝基二丙胺(NDPA)、N-亚硝基二丁胺(NDBA)、N-亚硝吗啉(NMOR)、N-亚硝基吡咯烷(NPYR)和N-亚硝基哌啶(NPIP) 7种对人体具有致癌活性的N-亚硝胺及其前体物进行分离净化,采用气相色谱-正化学源质谱法(GC-PCI/MS)对其进行定性定量分析。N-亚硝胺及其前体物的定量下限分别为1.25、5.0 μg/kg。方法灵敏度高,流程简单,适于批量样品的快速分析。13种家用橡胶手套样品中,7种N-亚硝胺的总迁移量为6.96~168.46 μg/kg,其中NDEA、NDMA和NDBA的检出频率最高,占N-亚硝胺总迁移量的比重最大。
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.
