    HASEGAWA T.; SUZUKI A.; YAMASHITA Y.
    Japan Tobacco Inc., Tobacco Science Research Center, Yokohama, Kanagawa, Japan.
    Charcoal is one of the most effective technologies applied to cigarette filters to remove volatile organic compounds (VOCs) from cigarette smoke in large quantities and substantially changes the characteristics of the smoke mainly due to adsorption. And a ...

    Degradation of cellulose acetate filters in natural environments - (II)

    SASAKI T.; YAMASHITA Y.; SHIBATA T.; SHINOZAKI M.; TOKIDA A.
    Japan Tobacco Inc., Tobacco Science Research Lab., Yokohama, Kanagawa, Japan.
    The degradation of cellulose acetate in natural environments (soil and water) was studied. It was observed that the degradation rate differed, depending on setting places. As presented last year in Vienna, the order of the degradation rate is as follows: ...
