基　　金：国家烟草专卖局卷烟减害技术重大专项"卷烟烟气中氨和氰化氢形成机理研究"(110200902002)和"卷烟烟气中酚类化合物形成机理研究"(110200902001)

摘　　要：为确定烟气中氰化氢的主要来源,采用卷烟模拟燃吸装置研究了卷烟烟气中氰化氢的前体成分,明确了前体成分与氰化氢释放量的量效关系。结果表明:烟气中氰化氢的主要前体成分为蛋白质、脯氨酸和天冬酰胺,它们对烟气中氰化氢的贡献率分别为85.13%、3.55%和1.59%;烟气中氰化氢释放量随着前体成分含量在一定范围内呈正线性相关关系。A smoking simulator of rapid heating was bulit to study precursors of hydrogen cyanide in cigarette smoke, which helped identify the dose-effect relationship between the precursors and HCN delivery. Results showed that the main precursors were protein, proline and asparagine amide with contribution rate to HCN delivery being 85.13%,3.55%and 1.59%respectively, presenting a positive linear correlationship between HCN delivery and the precursors.
