抽吸方式对卷烟主流烟气中主要羰基化合物释放量的影响

摘要

Effects of different smoking regimes, i.e. ISO, Massachusetts and Canadian, on major carbonyl compounds in mainstream cigarette smoke were investigated by HPLC. Results showed that yields of major carbonyl compounds from Canadian regime were the highest, especially in low-tar, highly ventilated filter cigarettes.%　　为考察抽吸方式对卷烟主流烟气中主要羰基化合物释放量的影响，以市售卷烟为实验材料，在吸烟机上采用ISO、Massachusetts和Health Canada 3种抽吸方式对10种卷烟分别进行了抽吸研究，然后采用高效液相色谱法测定了主流烟气中的主要羰基化合物的释放量。结果表明：相对于ISO抽吸方式，采用Massachusetts或Health Canada深度抽吸方式，羰基化合物的释放量均有显著提高，且以Health Canada深度抽吸方式下释放量最高；抽吸方式的改变对低焦油卷烟、高滤嘴通风率的卷烟的羰基化合物释放量影响更为显著。
