Toxic effect of nanotextiles as waste of respirators and face masks
AI summary Read the abstract
This ecotoxicological study tested the toxic effects of nanofibrous textiles from disposable face masks and respirators on aquatic organisms using standardized European test methods. The nano-scale fibers released from mask waste demonstrated ecotoxicological effects comparable to microplastic and nanoplastic exposures.
The article deals with the toxic effect of nanotextiles as waste from respirators and face masks.The article is focused on ecotoxicology and basic ecotoxicological tests according to available European standards and Czech legislation.Article describes the production and other characteristics of the nonwovens that were tested.Part of article concludes with a review of foreign studies that have also dealt with the testing of microplastics and nanoplastics on various organisms.The experimental results presents specific experimental characteristics of the textiles and then presents individual tests.Tests on seeds of Sinapis alba L. plants growing and Lemna minor L. were performed.In all cases, the tested non-woven fabrics had a non-toxic effect on the organisms, but it cannot be confirmed that there is no reaction.Further tests will be carried out to clarify the effects of the nonwovens on the test organisms.

Evaluation of the toxicological effects of microparticles from disposable masks on the test organism Oreochromis niloticus
AI summary Read the abstract
Researchers exposed Nile tilapia to microparticles shed from disposable COVID-19 face masks and found that polypropylene and polyester fibers from improperly discarded masks caused subchronic toxicity after 14 days of waterborne exposure. The study highlights how the massive increase in single-use mask disposal during the pandemic created a new and poorly recognized source of microplastic pollution in aquatic environments. Fish health effects from mask-derived microplastics add to growing concerns about the ecological legacy of pandemic-era waste.
Uncovering the release of micro/nanoplastics from disposable face masks at times of COVID-19
AI summary Read the abstract
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.
An ecotoxicological perspective of microplastics released by face masks
AI summary Read the abstract
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.
Impact of microfiber pollution on aquatic biota: A critical analysis of effects and preventive measures
AI summary Read the abstract
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.
Nanotechnology-enabled face masks: Balancing protection and pollution in aquatic environments
AI summary Read the abstract
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.
