Penetration of malonic dialdehyde on filtration of tobacco smoke

Abstract

It has been found that malonic dialdehyde penetrates through the filters of cigarettes. The filter cigarettes, such as "Club", "F6", "Cabinet", "Semper" and "Kenton" as well as non-filter cigarettes, namely "Salem", "Real" and "Karo" generate malonic dialdehyde during smoking, in amounts ranging from 15.6 to 44.3 mg/kg, i.e. from 20.4 to 44.3 mg/kg for cigarettes with filters and from 15.6 to 27.1 mg/kg for non-filter cigarettes.

Exhalation of malondialdehyde from the smoke of high grade cigarettes and effectiveness of filtering it

“…From comparison of MDA contents in smoke of cigarettes dealt with in this work to that occurring in smoke of cigarettes manufactured in Poland [26] and in the GDR [28] it results, that mean values for particular groups of cigarettes are much alike, but effectiveness of filtering is very differentiated in relation to the total contents of MDA and to the contents of this aldehyde in free or bounded form. Quality of filters in cigarettes having home reach [26,28] is absolutely unsatisfactory as compared to the effectiveness of such of high quality (of worldwide reach) cigarettes filters. Such cigarettes in spite of exhaling considerable amounts of MDA and of being considerably differentiated in particular brands, are provided with filters of high effectiveness.…”
