Characterization of environmental tobacco smoke by neutron activation analysis as a source of hazardous metals in indoor air pollution

The characterization of environmental tobacco smoke (ETS) as a source of heavy metals has been performed. Thirty elements were determined in 15 brands of cigarettes and their components. Five elements, Br, Cd, Cl, K, and Zn were found to be major elemental sources in the particulate phase of ETS. The elemental distribution in cigarette components was examined using a mass balance before and after cigarette smoking. The results show that most elements retain their major fraction in cigarette ash; only cadmium has a large emission (44%) in sidestream smoke, which thus makes cadmium a very important element of exposure to passive smokers. Elemental particle size distribution in ETS was measured in a room size chamber. The mass mean diameters ranged from 0.20 μm to 0.35 μm.
