The publication is a summary of research on the hazardous substances found in tobacco products. Studies of tar, nicotine and carbon monoxide in self-burning cigarettes on the market in Finland are based on control measures prescribed by Section 7 of the Tobacco Act, and the remaining studies of hazardous substances originate from the research activity referred to in Section 27 of the same act. The publication consists of five separate articles and a description of method in annex form. Tests on tar (dry smoke condensate), nicotine and carbon monoxide content in cigarette smoke were conducted in half-year periods from 1977 to 1980. The analytical and sampling methods employed are described herein. Variations in the content of hazardous substances in single cigarette brands and changes in the average content of harmful substances in all cigarette brands are also examined. The publication additionally classifies cigarette brands into groups according to tar content as well as investigates the correlation of nicotine and carbon monoxide to tar. The study also undertakes a determination of tar, nicotine and carbon monoxide content in Finnish nonself-burning cigarettes, papyros-type cigarettes, for which no international standard smoking method has been devised. The role of the puff frequence in the quantity of hazardous substances has also been studied in determining the content of harmful substances in papyros-type cigarettes. The analytical methods are dealt with and the results reported for a number of half-year periods. The publication describes tests with the methods used to determine hydrogen cyanide and particularly the spectrophotometric method adopted. The article presents research results obtained during three half-year periods for the hydrogen cyanide content found in the smoke of cigarette brands on the market in Finland. Research results reported in the literature and the correlation of hydrogen cyanide concentrations to tar are presented as well. Lead, cadmium and pesticide determinations were performed for some tobacco products in 1980. Lead and cadmium were analyzed in tobacco materials and in the tar produced in burning as were pesticide residuals in tobacco material. The results are compared with the values appearing in the relevant literature. Research on and research methods for roll-your-own brands of tobacco are dealt with. Results on the concentrations of tar, nicotine and carbon monoxide in smoke per hand-rolled cigarette and gramme of tobacco are reported for all hand-rolled tobacco marketed in Finland in 1980.
