The effect of smoking on ventilation requirements.

Reports measurements of suspended particulate matter, carbon monoxide and droplet nuclei in a climate chamber of 50m3 as indicators of the particulate and gaseous phase of cigarette smoke. Various combinations of smoking intensities andventilation rates between 1 and 16 air changes per hour were investigated partly by a standardized smoking machine procedure and by individual smoking by a panel of four persons. Results demonstrate that each characteristic component in the cigarettesmoke will follow its own elimination function, depending on adsorption to surfaces, agglomeration or other interaction processes in the enclosed aerosol. A ventilation rate of 60-80m3 per cigarette smoked seemed to be necessary to eliminate tobacco smoke from the room before its adsorption in the room.
