摘要
为考察不同抽吸方式对卷烟主流烟气总粒相物p H和化学成分的影响,采用ISO和Health Canada 2种抽吸方式分别抽吸了7种市售卷烟,然后测定总粒相物和烟碱释放量的差异以及总粒相物p H值的变化。研究表明:与ISO方案相比,采用Health Canada深度抽吸方式,总粒相物和烟碱释放量均有显著提高,但p H的增幅较小。
In order to investigate the influence of smoking regime on p H values of total particulate matter（ TPM） and chemical compounds in mainstream smoke,7 cigarette brands were tested with ISO standard method and Health Canada method,respectively. The differences of p H value,deliveries of TPM and nicotine in mainstream smoke were studied.The results showed that comparing with ISO standard method,the yields of TPM and nicotine in mainstream smoke determined by Health Canada method were significantly higher. However the p H value of TPM was slightly higher compared with ISO standard method.
