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

It has been found that malondialdehyde penetrates during smoking through filters and exhales with smoke from cigarettes 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 free form in the amount from 8.5 to 23.

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.

The optimum condition for malonic dialdehyde liberation from smoked fish and curing smoke condensates.

The aim of this study was to establish the conditions for malonic dialdehyde liberation from smoked fish and curing smoke condensates, as well as to determine its content in smoked fish. The specific absorption peaks of coloured solutions of malonic dialdehyde, from curing smoke condensates, with 2-thiobarbituric acid were determined. The conditions for malonic dialdehyde liberation were established, i.
