Abstract:In this study, the heavy metal content of burning agent and filler used in cigarette paper and the changes of heavy metal content of fiber raw materials in each beating stages were investigated. The results showed that a small amount of Cr in the burning agent was one of the sources of Cr in cigarette paper. And the filler contained heavy metal elements like As, Pb, Cd, Cr and Ni, especially Cr and Ni, which were the main source of heavy metal elements in cigarette paper. Additionally, the content of heavy metals in fiber raw material was very limited, so beating process was another important source of heavy metal in cigarette paper. |
