HEAVY-METALS IN TOBACCO AND TOBACCO-SMOKE .2. TRACE-METALS CADMIUM, LEAD, COPPER, COBALT AND NICKEL IN AUSTRIAN CIGARETTES AND IN PARTICLE PHASE AND SMOKE GAS

The trace metals cadmium, lead, copper, cobalt and nickel have been analyzed in 14 different Austrian filter cigarettes. The results show a good conformity thus allowing the calculation of a characteristic mean value. The same metals were analyzed separately in the gas and particle phase. From this data and the results obtained from butt and ash analysis, the sidestream concentrations and the transfer rates for both fractions could be evaluated. A classification into light and heavy cigarettes on the basis of heavy metal contents could not be made due to the similarity of the results.
