摘　　要：采用顶空固相微萃取结合气相色谱-质谱联用技术,研究了7类指甲油释放的挥发性有机物(VOCs),分析了涂覆前后指甲油中VOCs的释放率及其释放特征。结果显示,无处理的指甲油中可检测到78种VOCs,其中有21种已被列入《危险化学品目录》。不同类型指甲油的VOCs种类和含量存在显著性差异,主要的VOCs包括溶剂、光固化单体、增塑剂和抗氧化剂。在美甲过程中,风干或照干操作使大部分VOCs显著挥发,损失比例可达99%。美甲结束后,指甲油中的VOCs继续释放,油性指甲油、水性指甲油和UV甲油胶的VOCs释放半衰期分别为0.41、0.46和0.29 d。该研究为评估美甲产生的健康风险提供了重要数据支持。Nail polish is a cosmetic commonly used by modern women to beautify their nails.Tradi⁃tional oil-based nail polish has been widely reported to be harmful to human health.Although new wa⁃ter-based and UV gel nail polish take“non-toxic and harmless”as the slogan,their pungent odors is contrary to this.This study employed headspace solid-phase microextraction combined with gas chromatography-mass spectrometry to investigate the volatile organic compounds(VOCs)released from seven types of nail polish.We analyzed the release rates of VOCs before and after application,as well as their release characteristics post-application.Results showed that 78 VOCs were detected in untreated nail polish,21 of which are listed in the“Hazardous Chemicals Directory”.Signifi⁃cant differences were found in the types and contents of VOCs among different types of nail polish.The main VOCs include solvents,photoinitiators,plasticizers and antioxidants.During the nail ap⁃plication process,drying or curing operations cause most VOCs to volatilize significantly,with loss rates reaching up to 99%.After the nail application,VOCs continued to be released,with the halflives of VOCs release from oil-based,water-based and UV gel nail polish being 0.41,0.46,and 0.29 days,respectively.This study provides essential data support for assessing the potential health risks associated with the nail application.
