evidence: Factually inaccurate: The study specifically measured the levels of hazardous volatile organic compounds released from KF94 masks and found that these were about 100 to 1,000 times lower than the recommended exposure limit set by the U.S. National Institute for Occupational Safety and Health. This conflicts with the Mail’s claim that the masks "may expose wearers to dangerous level of toxic compounds linked to seizures and cancer". The study also wasn’t published by the NIH, but by a scientific journal unaffiliated with the NIH. August 2023 saw a revival of discussions over a possible return to mask mandates, amid concerns over rising COVID-19 cases. In the wake of this news, a Daily Mail article published on 27 August 2023 claimed that a "mask study published by NIH suggests N95 Covid masks may expose wearers to dangerous level of toxic compounds linked to seizures and cancer". [...] Overall, the Mail article’s representation of the Korean study, used to support its case that masks "may expose wearers to dangerous level of toxic compounds", is inaccurate and misleading, as it failed to tell readers key findings from the study showing that hazardous VOCs released from the masks were approximately 100 to 1,000 times lower than the recommended exposure limit. Health Feedback explained in several previous reviews how scientific evidence shows wearing a face mask reduces the spread of COVID-19.
