Resumen:

In this study, we report breath measurements, using a direct breath inlet connected to a using proton-transfer-reaction time of, flight mass spectrometer (PTRTOFMS), from 25 healthy adult volunteers in Mexico City, including both female and male individuals who reported to be either non-smokers, ex-smokers or smokers. In total, over 800 compounds have been identified as emissions from breath from the volunteers which include among others aliphatic and aromatic hydrocarbons, fatty acids, alcohols, carbonyls, and nitrogen or sulfur containing compounds. Exhaled breath can contain 1000s of VOCs but the exact chemical composition is dependent on the individual, and complex environmental factors including diet and exposure to indoor air pollution. This work tries to expand understanding of these factors using hierarchical clustering, and its potential usefulness in supplementing insights. © 2022 17th International Conference on Indoor Air Quality and Climate, INDOOR AIR 2022.
