The Influence of Metal Elements on the Conventional Smoke Indexes of Cigarettes Evaluated by Different Systems
In order to comprehensively evaluate the influence of metal elements on cigarette conventional smoke indexes,flame atomic absorption spectrometry was used to determine the contents of eight metal elements in 10 kinds of cigarette paper,5 kinds of cut tobacco and 49 kinds of cigarette samples formed by their combination,and the influence of metal elements on cigarette conventional smoke indexes was evaluated by statistical methods from three systems:smoke ash,cut tobacco/cigarette paper/smoke ash,cut tobacco/cigarette paper.The results show that:(1)The influence of metal elements in smoke ash on smoke quality is relatively low,and the metal elements in cut tobacco/cigarette paper can better reflect the influence of metal elements on various indexes.(2)The influence of metal elements in cut tobacco on smoke quality is greater than that in cigarette paper.(3)The metal elements that affect the quality of flue gas are mainly zinc and manganese in cut tobacco and calci-um,manganese and zinc in cigarette paper.The influence trend of the same element on different indexes is different.
