Abstract
Surgical face masks were introduced over a century ago to protect patients from infections during surgery. Initially designed to filter droplets from the mouth and nasopharynx, their use expanded to the general population during epidemic outbreaks. The COVID-19 pandemic, as the most significant modern health crisis, caused a dramatic rise in the use of personal protective equipment (PPE), particularly disposable surgical masks (DSMs). In Slovenia, DSMs were the most used face masks during the pandemic, with a notable portion (10%) improperly disposed of, leading to environmental contamination. To address these issues, a study was conducted to analyse waste DSMs and their environmental impact. A detailed disassembly and gravimetric analysis were performed, along with infrared spectroscopy of individual mask components. The materials used in DSMs raised concerns about micro/nanoplastic contamination and harmful substances released during leaching and photodegradation. Tests such as artificial weathering and the toxicity characteristic leaching procedure revealed that micro/nanoplastic particles were leached from all five mask components in water. Under natural conditions, DSMs lose up to 30% of their mass within a month, forming micro/nanoplastics through photodegradation. Improper disposal of DSMs thus poses a significant environmental risk due to the release of hazardous particles.
