Given the billions of masks used during COVID-19, this represents a significant and growing source of microplastic pollution.
The COVID-19 pandemic face mask waste: A blooming threat to the marine environment.
This review examines how single-use face masks — billions of which were discarded during the COVID-19 pandemic — contribute to microplastic and microfiber pollution in marine environments when improperly disposed of. The pandemic created a massive new source of plastic pollution, with masks breaking down into microplastics and releasing chemical contaminants in the ocean.
Neglected microplastics pollution in global COVID-19: Disposable surgical masks
Researchers found that disposable surgical masks release approximately 360 microplastic particles in still water, with the number increasing significantly under agitation or when exposed to detergents and alcohol. After just two months of natural weathering, the masks became fragile enough to potentially release billions of microplastic fibers upon entering water. The study highlights that pandemic-related mask waste represents a substantial and largely overlooked new source of microplastic pollution.
Facemasks: A Looming Microplastic Crisis
Single-use disposable face masks were shown to shed microplastic fibers during use and degradation, with billions of masks improperly discarded globally during the COVID-19 pandemic entering aquatic environments and releasing polypropylene and polyurethane fibers, adding a new and large-scale source of microplastic contamination.
Surgical face masks as a potential source for microplastic pollution in the COVID-19 scenario
Researchers investigated how disposable surgical face masks, widely used during the COVID-19 pandemic, could become a significant new source of microplastic pollution. The study notes that masks made of polymeric materials can release microplastic fibers into aquatic environments where they may be ingested by fish and other organisms. The findings suggest that face mask waste deserves focused attention as a microplastic source, including better waste management systems.
Recycling of disposable single-use face masks to mitigate microfiber pollution
Researchers mechanically recycled discarded disposable face masks into polypropylene-cotton blended fabrics, demonstrating an 83% reduction in microfiber release across the product lifecycle compared to masks, though complete elimination of fiber shedding was not achievable due to the inherent properties of textile materials.
Uncontrolled Disposal of Used Masks Resulting in Release of Microplastics and Co-Pollutants into Environment
This review documented the global distribution of discarded COVID-19 masks in terrestrial and aquatic environments and quantified the microplastics they release through degradation, finding that masks generate predominantly polypropylene fibers and fragments. The co-release of chemical additives from degrading mask materials was identified as an additional pollution concern beyond the MPs themselves.
