Real-time Analysis and Safety Assessment of Volatile Organic Compounds Emitted from Masks

Abstract

Objectives: The safety of distributed masks has been widely investigated following the coronavirus disease (COVID-19) pandemic. Although the unpleasant odor from masks is concerning, research on the toxicity of volatile organic compounds emitted from them is limited. Here, we aimed to quantify the VOCs emitted from masks and explore strategies for safe mask usage.

Methods: The VOCs emitted from 15 masks in five categories were measured. Proton transfer reaction time-of-flight mass spectrometry (PTR-TOF-MS, IONICON, Austria), which can rapidly and sensitively detect complex mixtures, was conducted. The test chamber connected to the equipment was comprised of uninterrupted acrylic and glass. PTR-TOF-MS data were analyzed using Tofware (PTR-MS Viewer 3.3, IONICON, Austria). Statistical analyses were performed using SPSS ver. 20 to determine the highest, lowest, and average concentrations of the VOCs (IBM SPSS Inc., USA). Analysis of variance (ANOVA) was conducted to compare the VOCs emitted from different masks.

Results: A total of 25 VOCs were detected among the 15 masks. The peak concentrations of formaldehyde, acrolein, isoprene, and benzene were higher than the exposure standards (Ceiling). The average concentrations of these compounds differed significantly among the mask samples (p < 0.05). The VOC concentration decreased gradually after approximately one hour.

Conclusions: Higher concentrations of VOCs were emitted from healthy, printed, and surgical masks compared to industrial masks. Further research is required to determine the factors affecting VOCs, such as mask material, temperature, and humidity. For safety, masks must be ventilated for at least an hour before usage.
