Abstract
In the experiments reported in this paper small traces of ethylene down to ppb level have been detected by means of photoacoustic spectroscopy in the breath exhaled from humans. The method has been applied in studying how the concentration of the ethylene coming out from human lungs is modified after smoking. We followed up the evolution of ethylene concentration in the case of several people by monitoring the ethylene before and after smoking. In each case the first exhaled air sample was collected prior smoking the cigarette and compared with the samples collected after 30 minutes following the inhalation of cigarette smoke. In all the experiments a high value of ethylene concentration was found immediately after smoking. The experimental laser based photoacoustic system has been realized in ENEA Laboratories in Frascati, Italy.
