Assessment of ETS Impact on Office Air Quality
The contribution of environmental tobacco smoke (ETS) to indoor air quality was investigated by quantifying the concentration of some of its constituents in the course of a series of strictly controlled experiments.
One brand of commercial cigarettes was smoked by trained smokers following a prescribed protocol both in a test-chamber and in an office of a modern, air-conditioned building. The ETS components investigated were CO, NO, NO2 and nicotone. The concentration of respirable suspended particles (RSP) was also monitored using three different methods.
The concentrations of these ETS constituents and their ratios are reported, together with background and outdoor levels. In addition, the influence of room ventilation, smoke generation rate, wall deposition effects, etc., is discussed.
