国产香烟矿物组成的初步研究

利用X射线衍射仪对28种国产香烟烟灰及其中的两种香烟(绿南京和云烟)的卷烟纸灰烬、烟丝以及过滤嘴中的矿物成分进行了研究.初步研究结果表明,香烟烟丝中含有一水草酸钙石,过滤嘴中不含任何矿物,烟灰中的矿物主要是方解石,此外还含有少量石英、钾盐、钾矾、石膏等矿物.这些矿物具有不同的来源:方解石来自卷烟纸,一水草酸钙石是烟叶生长期间自身合成的矿物,石膏是香烟燃烧过程中新形成的矿物.这些研究结果有可能为全面认识香烟致病机理提供一定的科学依据.

A preliminary study of mineral components of Chinese produced cigarettes

By means of X-ray diffraction (XRD), the authors studied the mineral components of cigarette ash from 28 kinds of Chinese-produced cigarettes as well as cigarette paper ash, cut tobacco and filter tip of 2 kinds of cigarette (Green Nanjing and Yunyan). The preliminary results obtained show that there is whewellite in cut tobacco, filter tip contains no minerals, and calcite is the dominant mineral composition in cigarette ash. Besides calcite, small amounts of quartz, sylvine, arcanite and gypsum are also existent in the cigarette ash. It is considered that these materials are derived from different sources: calcite comes from cigarette paper, whewellite is crystallized during the growth of tobacco leaf itself, and gypsum is formed in the combustion process of cigarette. These results provide scientific evidence for the comprehensive understanding of nosogenesis of cigarette.
