Abstract
A method to quantify the amount of tobacco smoke adhered on the surface material is proposed and the results of odor sensation experiment on adhered tobacco smoke using subjects are presented. First, we developed a new technique to quantify adhered tobacco smoke based on infrared spectroscopy. The experiment boxes were filled with different concentrations of tobacco smoke and after 14 hours tobacco smoke in the box was pulled out by ventilation. Then the subjects were asked to judge the intensity and acceptability of the odor of the air in the box. The odor in the box with a small amount of tobacco smoke adhered on the surfaces caused more than 60% of dissatisfied with one air change per hour. And it was showed that substance from tobacco smoke was adhered on the floor more than other surfaces. As results of field investigations we found that not only levels of tobacco smoke decides the amount adhered in the actual spaces.
