摘要

We have been effectively protected by disposable propylene face masks during the COV1D-19 pandemic; however, they may pose health risks due to the release of fine particles and chemicals.We measured micro/nanoparticles and organic chemicals in disposable medical masks, surgical masks, and (K)N9S respirators.In the breathing-simulation experiment, no notable differences were found in the total number of particles among mask types or between breathing intensities.However, when considering subranges, 80% of samples and 44 in <20% of samples.Three synthetic phenolic antioxidants were quantified, and A0168 reached a median concentration of 2968 ng/g.By screening particles collected from bulk mask fabrics, we detected 18 chemicals, including four commonly detected in masks, suggesting chemical partition between the particles and the fabric fibers and chemical exposure via particle inhalation.These particles and chemicals are believed to originate from raw materials, intentionally and nonintentionally added substances in mask production, and their transformation products.This study highlights the need to study the long-term health risks associated with mask wearing and raises concerns over mask quality control.
