ClearAntibacterial/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.
Viruses and Bacteria – Antiviral and Antibacterial Textile Materials: A Review
This review examines the development of antiviral and antibacterial textiles and masks designed to protect human health during pandemics. The paper surveys different antimicrobial agents and manufacturing methods, focusing on specifications that make these protective materials effective against both viruses and bacteria.
A Novel Face Masks and it’s Utility during COVID-19 Pandemic: A Comprehensive Review
This review examines the technical specifications, materials, and engineering advances of face masks used during the COVID-19 pandemic, including both commercial and homemade options. Researchers discuss the environmental impact of disposable masks, noting that their widespread use has contributed to microplastic pollution as mask materials degrade. The study highlights the need for mask designs that balance effective viral protection with reduced environmental contamination.
Recent Progress in Modified Polymer-Based PPE in Fight Against COVID-19 and Beyond
This review covers advances in modified polymer-based personal protective equipment materials for COVID-19 and future infectious disease scenarios, examining how antimicrobial coatings, nanoparticle additives, and advanced filtration polymers can improve PPE performance while minimizing microplastic shedding.
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.
Nanotechnology-enabled face masks: Balancing protection and pollution in aquatic environments
This review examined the dual role of nanotechnology-enhanced face masks in providing antimicrobial protection while also releasing micro- and nanoplastics into aquatic environments when improperly disposed. The authors call for better mask design standards and disposal strategies to balance protective benefits against environmental pollution.
A Critical Review on Reusable Face Coverings: Mechanism, Development, Factors, and Challenges
This review evaluated reusable face coverings as alternatives to disposable masks, examining filtration mechanisms, material developments, and key challenges including microplastic fiber shedding from textile-based coverings during use and washing.
Public face masks wearing during the COVID-19 pandemic: A comprehensive analysis is needed for potential implications
This review weighed evidence on the effectiveness of face masks for preventing COVID-19 transmission against growing evidence that masks release microplastics and chemical contaminants when worn and degraded. The authors concluded that the public health benefits of mask use during the pandemic outweighed plastic exposure risks, but called for redesigned masks with lower MP release and better end-of-life management.
Microplastics and chemical additives from disposable face masks: Environmental, human health and behavioural impacts
This review examined the environmental and health risks posed by microplastics and chemical additives released from synthetic disposable face masks. Researchers found that face masks are a substantial source of microplastic fibers and can leach harmful chemicals into both ecosystems and the human body. The study also explored how behavioral factors like mask disposal habits influence the overall pollution risk.
Functional Fiber Membranes with Antibacterial Properties for Face Masks
Researchers developed fiber-based membranes with built-in antibacterial properties for use in face masks, aiming to create filtration materials that can both block particles and actively kill pathogens to improve mask performance and safety.
Face Mask: As a Source or Protector of Human Exposure to Microplastics and Phthalate Plasticizers?
Researchers tested five types of face masks to determine whether they protect against or contribute to human inhalation of microplastics and phthalate plasticizers. They found that while masks filter out some airborne microplastics, they also release their own microplastic fibers and contain phthalate chemicals that wearers can inhale. The study suggests face masks have a dual role as both protectors and sources of microplastic and chemical exposure.
Current knowledge on the presence, biodegradation, and toxicity of discarded face masks in the environment
This review examines the environmental fate of discarded face masks from the COVID-19 pandemic, covering their degradation, chemical release, and ecological toxicity. 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.
Different Type of Face Masks and Their Protection Against Covid-19
This review examined the protective effectiveness of different face mask types against COVID-19. While focused on masks as infection control, surgical and N95 masks are a significant source of microplastic fibers released into the environment during use and disposal.
Nanotechnology-Enhanced Face Masks: Future Scopes and Perspectives
This review assessed nanotechnology-based approaches for creating reusable face masks, motivated by the massive single-use mask waste generated during the COVID-19 pandemic. Nano-enhanced masks with antimicrobial and self-cleaning properties were identified as a promising path toward reducing both environmental contamination and pathogen transmission.
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.
The Bad Side of Face Masks and How Bacteria Can Help
This review examines how single-use face masks contributed to environmental microplastic pollution during the COVID-19 pandemic and explores how bacteria and other microorganisms might be harnessed to biodegrade mask-derived microplastics in wastewater treatment systems.
Face Masks to Combat Coronavirus (COVID-19)—Processing, Roles, Requirements, Efficacy, Risk and Sustainability
This review examines the materials, manufacturing methods, and effectiveness of face masks used during the COVID-19 pandemic, most of which are made from non-biodegradable plastics like polypropylene and polyester. Researchers found that while masks are effective at reducing virus transmission, their widespread use and improper disposal have created a significant environmental concern as they break down into microplastics. The study calls for more sustainable mask materials and better waste management strategies to reduce the environmental footprint of pandemic-related plastic waste.
Applicability of Membranes in Protective Face Masks and Comparison of Reusable and Disposable Face Masks with Life Cycle Assessment
A comparison of reusable and disposable face masks using life cycle assessment found that while reusable masks have lower total environmental impact over their lifetime, disposable masks shed microplastic fibers that could enter both environmental and human biological systems.
Face Mask as a Tool to Prevent the Coronavirus Disease 2019: The Importance and Challenges
