Exhalation profile and elimination kinetics of mouth alcohol

Mouth alcohol (MA) is a potential source of error in alcohol breath-testing. Although utilized commercially for MA-detection, the exhalation profile of breath samples containing MA has not been systematically studied before. To characterize the exhalation profile of MA, volumetric expirograms of single-exhalations containing MA were examined. In addition, to explain reports of unusual slow elimina
