Microplastics, Год журнала: 2023, Номер 2(3), С. 278 - 303

Опубликована: Сен. 4, 2023

Microplastic pollution has become a global environmental concern with detrimental effects on ecosystems and human health. Effective removal of microplastics from water sources is crucial to mitigate their impacts. Advanced oxidative processes (AOPs) have emerged as promising strategies for the degradation elimination microplastics. This review provides comprehensive overview application AOPs in water. Various AOPs, such photocatalysis, ozonation, Fenton-like processes, shown significant potential microplastic degradation. These generate highly reactive species, hydroxyl radicals, which can break down into smaller fragments or even mineralize them harmless byproducts. The efficiency photocatalytic oxidation depends several factors, including choice photocatalysts, reaction conditions, physicochemical properties Furthermore, this discusses challenges associated oxidation, need optimization operating parameters formation harmful Overall, offers avenue water, contributing preservation aquatic safeguarding However, further research needed address limitations optimize implementation process effective sustainable remediation.

Photocatalysis toward Microplastics Conversion: A Critical Review

ACS Catalysis, Год журнала: 2024, Номер 14(11), С. 8694 - 8719

Опубликована: Май 20, 2024

Microplastics (MPs, particle size < 5 mm) have become increasingly ubiquitous on Earth due to the cleavage and degradation of heavy use plastics. MPs recently been reported be detected in human blood, alveoli, breast milk, embryos, other organs, raising concerns about their environmental risks. Photocatalysis has identified as a potential means for conversion, which utilizes solar energy stimulate semiconductor photocatalyst. However, study photocatalytic conversion is still incubation period. This review overviews current state-of-the-art technologies conversion. Then, fundamental principles, challenges, analytical techniques, evaluation indexes reforming are highlighted. We systematically summarized recent advances key factors influencing performance. Finally, we propose some perspectives developing efficient systems MPs. will provide guideline applying technology MPs, significantly contribute this emerging research field.

Colloid and Interface Science for Understanding Microplastics and Developing Remediation Strategies

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Фев. 14, 2025

Microplastics (MPs) originate from industrial production of <1 mm polymeric particles and the progressive breakdown larger plastic debris. Their environmental behavior is governed by their interfacial properties, which dominate due to small size. This Perspective highlights complex surface chemistry MPs under stressors discusses how physical attributes like shape roughness could influence fate. We further identify wastewater treatment plants (WWTPs) as critical hotspots for MP accumulation, where are inadvertently transferred sewage sludge reintroduced into environment. emphasize potential colloid science not only improve our fundamental understanding but also advance mitigation strategies in such WWTPs.

Aged polystyrene microplastics exacerbate alopecia associated with tight junction injuries and apoptosis via oxidative stress pathway in skin

Environment International, Год журнала: 2024, Номер 186, С. 108638 - 108638

Опубликована: Апрель 1, 2024

Microplastics (MPs) are pervasive pollutants in the natural environment and contribute to increased levels of illness both animals humans. However, specific impacts MPs on skin damage alopecia not yet well understood. In this study, we have examined effects two types polystyrene (pristine aged) hair follicle mice. UV irradiation changed chemical physical properties aged MPs, including functional groups, surface roughness, contact angles. vivo vitro experiments, cell injuries related oxidative stress, apoptosis, tight junctions (TJs), alopecia, mitochondrial dysfunction, other damages were observed. Mechanistically, can induce TJs via stress pathway inhibition antioxidant-related proteins, lead alopecia. The regulation apoptosis was also observed, is involved ROS-mediated signaling pathway. Importantly, showed exacerbated toxicity, which may be due their elevated irregularities altered compositions. Collectively, study suggests a potential therapeutic approach for caused by pollution.
