[Passive smoking].
One of the most important sources of indoor air pollution is tobacco smoke. It was the aim of the reported laboratory and field experiments to quantitatively determine both indoor air pollution by tobacco smoke and the acute health effects on man associated herewith. The results showed that of 472 workers who were interviewed, about 30% were complaining about the smoke at their working place, whereas 40% felt annoyed by the smoke and about 25% indicated eye irritation. The subjectively and objectively observed acute irritation effects and annoyances generally increase with an increasing smoke concentration. Healthy persons are expected to support irritation and annoyance from tobacco smoke concentrations which correspond to a tobacco-derived carbon monoxide concentrations of 1 - 2 ppm. Measures to protect passive smokers are recommended up from 1 ppm tobacco-derived carbon monoxide and are necessary up from 2 ppm. Calculating ventilation rates shows that at a constant smoke production of 1 cigarette/h, a ventilation with fresh air of 33 m3/h is necessary to maintain the upper limit of 2 ppm CO. This corresponds to 33 m3 of air per person and hour in a room occupied by 10 persons, and to 23 m3 of air per person and hour in a room with 100 persons.
