Identification of Sars-Cov-2 related volatile organic compounds from face masks

This study aims to identify SARS-CoV-2-related volatile organic compounds (VOCs) of the exhaled breath from face masks. Face masks collected from SARS-CoV-2 patients (n = 30) and the control group (n = 11) were analyzed to detect VOCs in the exhaled breath using the Headspace-Gas Chromatography Mass Spectrometry. Significant increases in concentrations of toluene, hexadecane, and phenol were detected in the face masks belonging to patient groups (p < 0.001). Clinical sig-nificance was further found in isobutyric acid levels considering Cohen's d value (p = 0.070). The findings of this study suggest that monitoring toluene, hexadecane, phenol, and isobutyric acid could provide considerable support in rapid screening of SARS-CoV-2.
