Abstract:

In late years, people are becoming increasingly concerned about body odors such as breath odor.
Furthermore, body odor of residents is drawing attention as it has an influence on comfort of indoor space. Main body odor is breath odor, scalp odor, axillary odor, foot odor and excrement odor. By the way, it may include "cigarette smoking" and "alcohol drinking". The present study aims at determining the emission rates of VOCs in the expired air. A human subject was tested for the expiration of target substances following the intake of 500mL of beer. The results showed that ethanol emission rates decreased from 381511[ug/h] to 341603 [ug/h] over 180 minutes after alcohol intakes. Acetone emission rates increased from 349 [ug/h] to 1240 (ugh) over 180 minutes after alcohol intake. Emission rates of acetone and 2-propanol of the cause of breath odor tend to increase with drink liqueur.
