Nasal Absorption of Organic Matter in Animal Experiments

Abstract

Most of the long-term tobacco smoke exposure experiments have been performed with animals inhaling through their nares. It seems important to know to what extent the tobacco smoke is resorbed in the nasal cavities. The experimental equipment consists of two gas analyzers and two recorders, one of each serving the gas stream which has passed through the nose of a living animal, and the reference gas stream, respectively. The results suggest that a significant amount of smoke is absorbed. The mean value from eight animals of organic matter absorbed was 32%.
