Kurzfassung:
Analysis of volatile organic compounds (VOCs) in human breath can provide
information about the current physiological state of an individual, such as
clinical conditions and exposure to exogenous pollutants. The blood-borne
VOCs present in exhaled breath offer the possibility of exploring
physiological and pathological processes in a noninvasive way. However, the
field of exhaled breath analysis is still in its infancy. We undertook this
study in order to define interindividual variation and common compounds in
breath VOCs of 48 young human volunteers. Alveolar breath samples were
analyzed by automated thermal desorption, gas chromatography with flame
ionization detector (FID) and electron capture detector (ECD) using SUPELCO
standards with 66 compounds. Predominant compounds in the alveolar breath of
analyzed subjects are ethylbenzene, 1-ethyl-4-methylbenzene,
1,2,4-trimethylbenzene and 1,3,5-trimethylbenzene (over 50% of the subjects).
Isopropyl alcohol, propylene, acetone, ethanol were found as well. We
detected substituted compounds in exhaled breath.
