Abstract
The present study aims at determining the emission rates of aldehydes and VOCs in the expired air of human subjects before and after intake of an alcoholic beverage. A male subject was measured for the expiration of target substances following the intake of 500mL of beer. We clarified the emission rates of aldehydes and VOCs, and the change of emission rates following the intake beer. The results revealed that acetaldehyde emission rates decreased from 239 μg/h to 105 μg/h over 180min after alcohol intake. Ethanol emission rates decreased from 15897 μg/h to 10386 μg/h over 180min after alcohol intake. Future problems in this study, we must examine bad smell counter measures technique and products at the time of the drinking.
