Abstract

A laser sensor realised at ENEA Frascati (Italy) based on photoacoustic spectroscopy (PAS), able to detect gas concentrations down to sub-ppb level, was applied for revealing ethylene traces emitted in the exhaled breath by human subjects, before as well as after an antioxidant treatment. In the present work, the changes in breath ethylene detected by PAS, compared to a direct analysis of reactive oxygen species detected in the blood by a spectrophotometric method (d-ROMs), were investigated in each patient. The sensorial system, the methods, the experiment and the results are discussed in the paper.
