ClearSurgical 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.
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.
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.
Face masks: a COVID-19 protector or environmental contaminant?
This review examined how the massive global use of disposable face masks during COVID-19 has created a significant source of microplastic pollution, with billions of masks entering the environment and releasing plastic fibers and chemical contaminants.
Uncovering the Release of Micro/nanoplastics from Disposable Face Masks at Times of COVID-19
Researchers found that disposable face masks release significant amounts of micro- and nanoplastic particles when subjected to water exposure and mechanical stress similar to environmental conditions. This confirms that the massive use of masks during COVID-19 introduced new sources of microplastic pollution into the environment.
Covid-19 face masks: A potential source of microplastic fibers in the environment
This commentary highlights that the massive global increase in disposable face mask production during the COVID-19 pandemic has created a significant new source of microplastic fiber pollution, as mask materials shed synthetic fibers into the environment.
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.
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.
Exudation of microplastics from commonly used face masks in COVID-19 pandemic
Researchers simulated real-world mask usage and found that commonly used face masks — including surgical and cloth types — shed measurable quantities of microplastic particles that could be inhaled by the wearer, raising concerns about respiratory exposure during prolonged mask use.
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.
A review of disposable facemasks during the COVID-19 pandemic: A focus on microplastics release
This review examines the environmental threats posed by disposable face masks used during the COVID-19 pandemic, with a focus on microplastic release. Researchers found that discarded masks undergo physical and chemical degradation in the environment, generating microplastics that contaminate both aquatic and terrestrial ecosystems. The study provides an overview of current knowledge on microplastic extraction methods and proposes strategies for controlling mask-related plastic pollution through source reduction and improved waste management.
Microfiber releasing into urban rivers from face masks during COVID-19
Researchers investigated microfiber release from discarded face masks in urban rivers during COVID-19, finding that masks shed substantial quantities of synthetic microfibers that contribute to freshwater microplastic contamination.
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.
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.
Preliminary study on the ejection of microplastics from different types of face masks
Researchers tested surgical masks, cloth masks, and N95 respirators to see how many microplastics they release. They found that all types shed microplastic fibers, with surgical masks releasing the most particles, and that used masks shed more than unused ones. The study raises awareness that face masks, while important for health protection, are themselves a source of microplastic exposure.

Microplastics from face masks: A potential hazard post Covid-19 pandemic
Researchers quantified the annual face mask usage and associated plastic waste across 36 countries during the COVID-19 pandemic, estimating total annual mask usage exceeding 1.5 million tonnes and associated plastic waste of approximately 4.2 million tonnes. The study highlights that global COVID-19 responses substantially increased environmental microplastic burdens from single-use face mask disposal.

The study provides the first quantitative evidence of how pandemic-related mask waste may contribute to plastic pollution in aquatic ecosystems.
Face masks as a source of nanoplastics and microplastics in the environment: Quantification, characterization, and potential for bioaccumulation
Researchers found that each surgical or N95 face mask can release over one billion nanoplastic and microplastic particles, mostly smaller than one micrometer, when they break down. The study also detected microplastics in the nasal mucus of mask wearers, suggesting inhalation exposure during use. Additionally, mask-derived particles were shown to adsorb onto marine organisms across different levels of the food chain, raising concerns about both human health and environmental impacts.
