Face mask structure, degradation, and interaction with marine biota: A review
Single-use face masks, which surged in use during COVID-19, are a significant source of microplastic pollution because they degrade into tiny plastic fragments and also serve as rafts for harmful bacteria, pathogens including SARS-CoV-2, and antibiotic resistance genes in aquatic environments. This review underscores that the environmental and public health costs of mask disposal extend well beyond simple litter, carrying risks for water quality and the spread of antimicrobial resistance.
Impact of face mask microplastics pollution on the aquatic environment and aquaculture organisms
This review examines how the widespread use of disposable face masks during the COVID-19 pandemic has contributed to microplastic pollution in aquatic environments. Researchers found that mask materials made from polymers like polypropylene break down into microplastics through UV radiation and weathering, causing harm to aquatic organisms including reduced growth, neurotoxicity, and increased mortality. The study recommends developing biodegradable alternatives to plastic-based face masks to reduce environmental impact.
Antibacterial/Antiviral Face Masks: Processing, Characteristics, Challenges, and Sustainability
This review examines the development of antibacterial and antiviral face masks — including the materials, processing methods, and antimicrobial agents used — and discusses sustainability challenges associated with mask disposal. It is tangentially relevant to microplastics because single-use masks are now recognized as a significant emerging source of microplastic and nanoparticle pollution when they fragment in the environment, though this paper focuses primarily on mask performance and design rather than their pollution impact.
Uncovering the release of micro/nanoplastics from disposable face masks at times of COVID-19
Researchers investigated how disposable face masks release micro- and nanoplastics when exposed to mechanical stress in water, simulating environmental weathering. They found that even minimal deterioration of a single mask could release thousands of microplastic fibers and up to ten billion nanoscale particles. The study provides the first quantitative evidence of how pandemic-related mask waste may contribute to plastic pollution in aquatic ecosystems.
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.
Impact of microfiber pollution on aquatic biota: A critical analysis of effects and preventive measures
This review examines how microfibers from textiles, face masks, and other personal protective equipment are polluting aquatic environments, a problem worsened by the COVID-19 pandemic. Microfibers enter waterways through washing machines and waste treatment plants, where they can be ingested by aquatic organisms. The authors highlight the urgent need for better filtration technologies and waste management to reduce microfiber contamination in oceans and freshwater systems.
An ecotoxicological perspective of microplastics released by face masks
This review assessed the ecotoxicological hazard of microplastics derived from face masks, which were produced in unprecedented quantities during the COVID-19 pandemic. The authors identified significant uncertainties about real-world impact concentrations and called for standardized testing to better characterize the toxicity of face mask-derived microplastics to aquatic and terrestrial organisms.
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.
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.
