Penetration of malonic dialdehyde on filtration of tobacco smoke

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.
