電子煙已成為國際煙草關注的焦點和發展的熱點,也是我國煙草行業新型煙草制品發展的一個重要方向.對近幾年國內外關于電子煙煙液、煙具和氣溶膠中化學成分的風險研究文獻和相關法規的進行了收集、分類、比較和分析,從以下三個方面對電子煙中化學成分風險研究現狀進行闡述,以期為電子煙安全性研究提供參考:1)煙液和氣溶膠中煙堿、醛酮類化合物、揮發性化合物、煙草特有亞硝胺和金屬元素等相關研究;2)電子煙氣溶膠與卷煙煙氣中有害成分的對比研究;3)煙具中有害成分遷移量的分析研究.

Abstract： 

Electronic cigarettes(e-cigarettes)have become the focus of international tobacco companies and served as an important part in the new tobacco products in China.Literature review was conducted in terms of chemical evaluation of e-cigarettes in recent years.In this article,related studies on e-liquids(in cartridges and in refill bottles),aerosols and hardware were reviewed.Levels of nicotine,aldehydes,ketones,volatile organic compounds(VOCs),tobacco-specific nitrosamines(TSNAs)and metals in e-liquid and aerosols were summarized.Comparison of toxins levels between conventional and e-cigarettes was conducted.Migration levels of hazardous substances in hardware were also investigated.A starting point for safety evaluation of e-cigarettes in the future was provided.
