分别测定38种具代表性卷烟烟丝中总烟碱、游离态烟碱、结合态烟碱的含量和烟气总粒相物pH,通过简单相关性和内在关联性分析方法,研究卷烟烟丝中烟碱不同形态与烟气总粒相物pH的关联性。简单相关性分析结果表明,游离烟碱含量与卷烟烟气总粒相物pH呈显著正相关,相关系数为0.846,游离烟碱和总烟碱之比与卷烟烟气总粒相物pH呈显著正相关,相关系数为0.784。内在关联分析结果表明,总烟碱含量对烟气总粒相物pH影响显著(P=0.016)。
The content of total nicotine, free nicotine, bound nicotine and pH of total particulate matter (TPM) value of domestic tobacco from 38 representational brands were measured and the relationship between the nicotine forms and TPM pH of cigarettes smoke were investigated by simple correlation analysis and intrinsic relevance analysis. The results of the simple correlation analysis showed that the content of free nicotine was significantly positively correlated with TPM pH with a correlation coefficient of 0.846, the ratio of free nicotine to total nicotine showed a significantly positively correlation with TPM pH with a correlation coefficient of 0.784. The result of intrinsic relevance analysis showed that the content of total nicotine affect the TPM pH markedly (P=0.016).
