In recent years, Electrospinning (ES) has been revealed to be a straightforward and innovative approach manufacture functionalized nanofiber-based membranes with high filtering performance against fine Particulate Matter (PM) proper bioactive properties. These qualities are useful for tackling current issues from bacterial contamination on Personal Protective Equipment (PPE) surfaces the reusability of both disposable single-use face masks respirator filters. Despite fact that conventional ES process can upscaled promote high-rate nanofiber production, number research works design hybrid materials embedded in electrospun mask application is still low mainly carried out at laboratory scale. this work, multi-needle was employed continuous processing manufacturing pristine Poly (Vinylidene Fluoride-co-Hexafluoropropylene) (PVDF-HFP) nanofibers membrane ones TiO2 Nanoparticles (NPs) (PVDF-HFP@TiO2). The were collected Polyethylene Terephthalate (PET) nonwoven spunbond fabric characterized by using Scanning Electron Microscopy Energy Dispersive X-ray (SEM-EDX), Raman spectroscopy, Atomic Force (AFM) analysis. photocatalytic study performed proved PVDF-HFP@TiO2 provide significant antibacterial activity Staphylococcus aureus (~94%) Pseudomonas aeruginosa (~85%), after only 5 min exposure UV-A light source. addition, exhibit filtration efficiency submicron particles (~99%) pressure drop (~3 mbar), accordance standard required Filtering Face Piece (FFPs). Therefore, these results aim real perspective producing polymer-based nanotextiles self-sterilizing properties implementation advanced large

Disposable masks, formed mainly from polymers, often incorporate various chemical additives to enhance their performance. These additives, which include plasticizers, may be released during mask usage, presenting a novel source of human exposure these compounds. In this study, the presence 16 organophosphate esters (OPEs), 11 phthalates, and four alternative in types face were studied, as well release simulated use (artificial laboratory conditions). Total plasticizer concentrations exhibited minimal variation across different types, with mean values 7.27 µg/face for surgical, 8.61 reusable, 11.0 KN-95, 13.9 FFP2 masks. To explore behavior, inhalation experiments conducted under conditions. The findings revealed significant temperature-dependent enhancement subsequently increasing exposure. showed percentages, ranging 0.1 95 %, depending on specific compound type. Notably, OPEs percentage 1.0 similar 1.2 % release. Although plasticizers less frequently released, they still presented notable 4.1 %. Daily intake estimations via ranged 0.01 9.04 ng/kg body weight (bw)/day additives. Using estimations, carcinogenic non-carcinogenic risks associated compounds evaluated. All calculated studied paper remained below established threshold limits. However, do represent an additional pathway that, when considered alongside other more predominant routes such indoor/outdoor inhalation, dermal absorption, dietary intake, makes total worthy consideration.

Microplastics (MPs) refer to tiny plastic particles, typically smaller than 5 mm in size. Due increased mask usage during COVID-19, improper disposal has led masks entering the environment and releasing MPs into surroundings. can absorb environmental hazards transfer them humans animals via food chain, yet their impacts on safety human health are largely neglected. This review summarizes release process of from face masks, influencing factors, safety. Highlights given prevalence combined toxicities with other hazards. Control strategies also explored. The is affected by factors like pH, UV light, temperature, ionic strength, weathering. chemical active surface large area, act as vectors for heavy metals, toxins, pesticides, antibiotics antibiotic resistance genes, foodborne pathogens through different mechanisms, such electrostatic interaction, precipitation, bioaccumulation. After being adsorbed MPs, toxicity these hazards, oxidative stress, cell apoptosis, disruption metabolic energy levels, be magnified. However, there a lack comprehensive research both well corresponding control strategies. Future should prioritize understanding interaction toxicity, integrating detection degradation methods
