Detection of Various Microplastics in Patients Undergoing Cardiac Surgery

Environmental Science & Technology, Год журнала: 2023, Номер 57(30), С. 10911 - 10918

Microplastics have been detected in human stool, lungs, and placentas, which direct exposure to the external environment through various body cavities, including oral/anal cavity uterine/vaginal cavity. Crucial data on microplastic completely enclosed organs are still lacking. Herein, we used a laser infrared chemical imaging system scanning electron microscopy investigate whether microplastics exist heart its surrounding tissues. Microplastic specimens were collected from 15 cardiac surgery patients, 6 pericardia, epicardial adipose tissues, 11 pericardial 3 myocardia, 5 left atrial appendages, 7 pairs of pre- postoperative venous blood samples. not universally present all tissue samples, but nine types found across five with largest measuring 469 μm diameter. Nine also samples maximum diameter 184 μm, type distribution showed alterations following surgical procedure. Moreover, presence poly(methyl methacrylate) appendage, tissue, cannot be attributed accidental during surgery, providing evidence patients undergoing surgery. Further research is needed examine impact introduction potential effects internal health.

Piezoelectric Nanofiber Membrane for Reusable, Stable, and Highly Functional Face Mask Filter with Long‐Term Biodegradability

Advanced Functional Materials, Год журнала: 2022, Номер 32(20)

Опубликована: Фев. 9, 2022

Abstract The emergence of the SARS‐CoV‐2 pandemic and airborne particulate matter (PM) pollution has led to remarkably high demand for face masks. However, conventional respirators are intended single use made from nondegradable materials, causing serious concern a plastic‐waste environmental crisis. Furthermore, these facemasks weakened in humid conditions difficult decontaminate. Herein, reusable, self‐sustaining, highly effective, humidity‐resistant air filtration membrane with excellent particle‐removal efficiency is reported, based on controllable stable piezoelectric electrospun poly (l‐lactic acid) (PLLA) nanofibers. PLLA filter possesses ( > 99% PM 2.5 91% 1.0) while providing favorable pressure drop ≈ 91 Pa at normal breathing rate) human due charge naturally activated by respiration through mask. long, performance good humidity resistance, demonstrated minimal declination nanofiber after moisture exposure. reusable via common sterilization tools (i.e., an ultrasonic cleaning bath, autoclave, or microwave). Moreover, prototype completely biodegradable nanofiber‐based facemask fabricated shown decompose within 5 weeks accelerated degradation environment.

“Functional upcycling” of polymer waste towards the design of new materials

Chemical Society Reviews, Год журнала: 2023, Номер 52(14), С. 4755 - 4832

Опубликована: Янв. 1, 2023

Diversification of polymer waste recycling is one the solutions to improve current environmental scenario. Upcycling a promising strategy for converting into molecular intermediates and high-value products. Although catalytic transformations small molecules have been actively discussed, methods characteristics upcycling new materials not yet addressed. Recently, functionalisation wastes (polyethylene terephthalate bottles, polypropylene surgical masks, rubber tires, etc.) their conversion with enhanced functionality proposed as an appealing alternative dealing recycling/treatment. In this review, term 'functional upcycling' introduced designate any method post-polymerisation modification or surface without considerable chain destruction produce upcycled material added value. This review explores functional detailed consideration most common polymers, i.e., polystyrene, poly(methyl methacrylate), polyethylene, polypropylene, polyurethane, polyethylene terephthalate, polyvinyl chloride, polycarbonate, rubber. We discuss composition plastic waste, reactivity, available physical/chemical agents modification, interconnection between properties application. To date, successfully applied adsorbents (including CO2), catalysts, electrode energy storage sensing, demonstrating high Importantly, reviewed reports indicated that specific performance generally comparable higher than similar prepared from virgin feedstock. All these advantages promote diversification approach against postprocessing employed waste. Finally, identify limitations suggest future scope research each polymer, we comparatively analysed aspects those chemical mechanical recycling, considering resource costs, toxicity used chemicals, footprint, value product.
