A novel VOC breath tracer method to evaluate indoor respiratory exposures in the near- and far-fields; implications for the spread of respiratory viruses
H. Parhizkar, M. Fretz, et al.
This innovative study by Hooman Parhizkar, Mark Fretz, Aurélie Laguerre, Jason Stenson, Richard L. Corsi, Kevin G. Van Den Wymelenberg, and Elliott T. Gall uses breath mint's volatile organic compounds (VOCs) to evaluate respiratory exposure indoors. Findings reveal that close-range exposures are significantly higher initially, while longer durations highlight the importance of far-field exposure, providing critical insights into airborne disease transmission.
