✦ Synopsis

It has been found that malondialdehyde penetrates during smoking through filters and exhales with smoke fromcigarettes such as : "Pall Mall", "Winston", "Camel", "Lucky Strike", "Kansas", "Mustang", "Ronson", "Chesterfield", "Rally", "Oscar" and "Marlboro". These cigarettes exhale malondialdehyde in a different way, in freeformin theamountfrom8.5 to23.5 mgjkgcigarettesonanaverageof 13.3 mg/kgforthewholegroup andtotally(infreeand boundedform) from9.5 to26.5 mg/kg(average 16.9 mg/kg). Moreover,ithasbeenfound that filters retain this aldehyde in free form on an average of 9.9 mg/kg and totally (in free and bounded form) of 19.0 mg/kg. Without filters these amounts would increase aldehyde contents in smoke by 42.7 and 52.9 %, respectively. Low malonalogenic properties of tobacco, high effectiveness of cigarette filters, high degree of tar deposition befor inhaling into lungs and slow (6 min and longer) smoking decide about low level ofexhalation of malondialdehyde in cigarette smoke.
