Abstract

Objective: To evaluate the room-to-room distribution of environmental tobacco smoke (ETS) in two typical homes with low ventilation rates. Methods: Cigarettes were smoked in one room and airborne tobacco smoke components (nicotine, isoprene, and particles) and the mutagenic activity of the particulate matter were measured simultaneously in that room and several other rooms in the homes. Results: With the exception of nicotine, the measured components had similar concentrations in all rooms. The nicotine concentrations were much lower in adjacent rooms than in the smoking room. Conclusions: Non-smoking occupants in typical smoking homes will be exposed to ETS in whichever room they stay. Nicotine disappears faster from room air than other ETS components.
