Researchers found that disposable masks break down slowly in the environment, releasing microplastic fibers and chemical additives that harm aquatic and terrestrial organisms. The study calls for improved disposal practices and further research into the long-term environmental consequences of pandemic-related mask waste.
Microplastics/nanoplastics released from facemasks as contaminants of emerging concern
This review examines how disposable facemasks, made primarily from polypropylene and polyethylene, release microplastics and nanoplastics into the environment. Chemical, physical, and biological processes break down discarded masks into tiny plastic particles that persist in ecosystems. Given the billions of masks used during COVID-19, this represents a significant and growing 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.
Impact of coronavirus pandemic litters on microfiber pollution—effect of personal protective equipment and disposable face masks
Researchers reviewed microfiber pollution arising from disposable and reusable face masks and personal protective equipment during the COVID-19 pandemic, finding that synthetic fiber shedding through littering, laundry, and disinfection represents a significant and undercharacterized addition to global microplastic pollution loads.
Environmental risks of polymer materials from disposable face masks linked to the COVID-19 pandemic
This review examines how disposable face masks from the COVID-19 pandemic release microplastics into terrestrial and aquatic ecosystems, discussing combined pollutant effects and proposing green technologies to reduce mask-related plastic waste at its source.
Fate of the face masks in the environment affect human and wildlife: tons of face masks are new source for the endocrine disrupting chemicals
Researchers examined how the massive accumulation of discarded COVID-19 face masks — primarily made of polypropylene, an endocrine-disrupting plastic — represents a new source of microplastic pollution in soils, oceans, and air worldwide. The paper discusses the health and ecological risks posed by mask-derived microplastics and endocrine disruptors for both humans and wildlife.
Used disposable face masks are significant sources of microplastics to environment
Researchers evaluated whether disposable face masks release microplastics into water and found that used masks released significantly more particles than new ones, increasing from about 183 particles per piece for new masks to much higher levels after use. The study suggests that the massive increase in disposable mask consumption during the COVID-19 pandemic has made improperly discarded masks a significant new source of microplastic pollution.
Kinetic characteristics of microplastic release from commonly used masks in aquatic environment
Researchers tested four mask types (normal, fashion, N95, and disposable surgical) by exposing them to simulated natural water environments over 12 months at 3-month intervals to characterize the kinetics of microplastic release. They found time-dependent release patterns that varied by mask construction, documenting structural degradation and quantifying microplastic fiber shedding as a function of duration, with implications for environmental risk assessment of pandemic-related mask pollution.
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.
Release of microfibers from surgical face masks: an undesirable contributor to aquatic pollution
Researchers found that surgical face masks release large quantities of microfibers when exposed to aqueous conditions, identifying masks — whose global use surged during the COVID-19 pandemic — as a significant and underappreciated source of microplastic pollution in aquatic environments.
