Cadmium in Tobacco and Its Fate during Smoking,

PB88248331

Publication Date	1988
Personal Author	Petering, H. G.; Menden, E. E.; Michael, L. W.
Page Count	8
Abstract	Using a smoking machine, reference cigarettes, a commercial brand of nonfilter 85 millimeter cigarettes, a medium priced cigar, and a popular brand of pipe tobacco, both wet ashing and dry ashing procedures were carried out to determine the cadmium (7440439) content to which smokers were being exposed. Cigarettes varied from 1.31 to 1.28 micrograms (microg) of cadmium per cigarette, which corresponded to 1.17 to 1.62 microg per gram (g) of cigarette. For cigar tobacco a total of 1.86 microg/g was found and in pipe tobacco the content was 0.93 microg/g. Only 6 to 7 percent of the cadmium in the smoked portion of the cigarette appeared in the tar, while the unsmoked butts were enriched with 10 to 27 percent of the cadmium of the smoked portions. The authors suggest that the remaining cadmium, 50 to 55 percent, is lost in the sidestream during smoking and between puffs. This indicated that not only is the one smoking at risk from cadmium exposure, but so are the others present in the vicinity.
