It is known that the thermal environmental factors, such as air temperature, air humidity and so on, affect the perceived air quality of people in the room, but there are few studies focusing on odorous substances and physiological elements such as skin temperature and skin moisture content on emission sites. In this study, we conducted an experiment aimed at grasping effect of exposed temperature on dermally-emitted bioeffluents. Each subject stayed in the climate chamber set at 23 o C, and 30

... o C as well, at which time bioeffluents were collected from their skin surface. 7 target substances are as follows; Acetaldehyde, Ethanol, Acetone, Acetic acid, 2-Ethyl-1-hexanol, Toluene and Ammonia. The emission flux of Acetone was significantly larger under the condition of 30 o C, and there was a tendency that the emission flux of the other 5 substances except Ammonia were also larger at 30 o C condition. In addition, the emission flux of ammonia from subjects who voted high values in the stress sensation was large.
