摘  要:
运用GC-MS法研究了在卷烟烟支中分别加入胆甾醇、麦角甾醇、豆甾醇和β-谷甾醇对主流烟气中14种多环芳烃释放量的影响并探讨了甾醇类物质在卷烟燃吸时产生多环芳烃的机理。结果表明:游离甾醇的总量与主流烟气中多环芳烃的总释放量以及苯并[a]芘的释放量都呈显著正相关,而不同甾醇类物质对主流烟气中不同的多环芳烃含量的影响是有差异性的,胆甾醇显著地影响三环多环芳烃的释放量,β-谷甾醇显著地影响四环多环芳烃的释放量,豆甾醇对于四环、五环、六环多环芳烃的释放量的影响很显著,麦角甾醇对所有PAHs的释放量都有显著的影响。

摘  要:
Relation between addition levels of cholesterol,ergosterol,stigmasterol,and β-sitosterol into cigarettes and delivery of 14 types of PAHs was studied by GC-MS with standard method.Results showed that there were significant positive correlations between quantity of free phytosterols and the delivery of PAHs and benzo[a]pyrene,and diverse phytosterols' effects on the delivery of various types of PAHs were different when the addition level changed.The delivery of three-ring PAHs and four-ring PAHs were significantly influenced by cholesterol and β-sitosterol,respectively.The delivery of four,five,six ring PAHs were significantly influenced by stigmasterol,and delivery of all ring PAHs were significantly influenced by ergosterol.
