摘要
目的:用《ISO/CD 29941委员会草案》的标准方法对中国10种市售天然避孕套中致癌物亚硝胺的迁移量进行检测分析,为制定乳胶避孕套中亚硝胺迁移量的国家标准检测方法提供了可靠的依据。方法:从中国市场上随机购买了10种天然乳胶避孕套,用《ISO/CD 29941委员会草案》标准方法,将避孕套在水中浸提10 min后,用二氯甲烷萃取,再经干燥和浓缩后利用气相色谱法-热能分析仪检测从乳胶避孕套中迁移出的亚硝胺含量。结果:二甲基亚硝胺(NDMA)、二乙基亚硝胺(NDEA)和二丁基亚硝胺(NDBA)被检出。在10 min之内,从10种天然乳胶避孕套中NDMA的迁移量为0~18.74μg/kg,NDEA的迁移量为1.53~14.69μg/kg,NDBA的迁移量为0~39.54μg/kg,总亚硝胺迁移量为9.87~50.52μg/kg。仅有一种样品符合93/11/EEC的亚硝胺限量标准。结论:我国市售天然乳胶避孕套中亚硝胺迁移量较高,建议制定乳胶避孕套中亚硝胺迁移量检测的国家标准方法及迁移量的限量标准。
Objective:To detect nitrosamines migration from nature latex condoms in the China market and provide basis for constituting national standard.Methods:Nitrosamines migration from 10 nature latex condoms was monitored according ISO/CD 29941 Committee Draft.Results:N-nitrosodimethylamine(NDMA),N-nitrosodiethylamine(NDEA) and N-nitrodibutylamine(NDBA) were found in 10 samples.The migration level of NDMA,NDEA and NDBA varied was 0~18.74 μg/kg,1.53~14.69 μg/kg and 0~39.54 μg/kg,respectively.The migration level of total nitrosamines varied was 9.87~50.52 μg/kg.Conclusion:In view of high content and potential toxicity of nitrosamines migration from latex condoms,it is suggested that a national standard and a prescribed limit should be imposed.
