Microplastics Derived from Food Packaging Waste—Their Origin and Health Risks

Materials, Год журнала: 2023, Номер 16(2), С. 674 - 674

Опубликована: Янв. 10, 2023

Plastics are commonly used for packaging in the food industry. The most popular thermoplastic materials that have found such applications polyethylene (PE), polypropylene (PP), poly(ethylene terephthalate) (PET), and polystyrene (PS). Unfortunately, plastic is disposable. As a consequence, significant amounts of waste generated, entering environment, undergoing degradation processes. They can occur under influence mechanical forces, temperature, light, chemical, biological factors. These factors present synergistic or antagonistic effects. result their action, microplastics formed, which undergo further fragmentation decomposition into small-molecule compounds. During process, various additives at plastics' processing stage also be released. Both negatively affect human animal health. Determination negative consequences on environment health not possible without knowing course processes products. In this article, we sources microplastics, causes places formation, transport particles, plastics often production storage, affecting said its

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.

Aeration-Free In Situ Fenton-like Reaction: Specific Adsorption and Activation of Oxygen on Heterophase Oxygen Vacancies

Environmental Science & Technology, Год журнала: 2024, Номер 58(4), С. 1921 - 1933

Aeration accounts for 35–51% of the overall energy consumption in wastewater treatment processes and results an annual 5–7.5 billion kWh. Herein, a solar-powered continuous-flow device was designed aeration-free situ Fenton-like reactions to treat wastewater. This system is based on combination TiO2–x/W18O49 featuring heterophase oxygen vacancy interactions with floating reduced graphene/polyurethane foam, which produces hydrogen peroxide at rates up 4.2 ppm h–1 degradation more than 90% various antibiotics. The vacancies play important role stretching O–O bond by regulating d-band center TiO2–x/W18O49, promoting hydrogenation *·O2– or *OOH H+ enrichment, accelerating production reactive species spontaneous adsorption peroxide. Furthermore, mechanisms antibiotics actual were thoroughly investigated. In short, study provides meaningful reference potentially undertaking "aeration-free" Fenton reaction, can help reduce even completely eradicate aeration costs requirements during

Microplastics, which are small plastic particles, have become a growing environmental concern due to their prevalence in aquatic and terrestrial environments. They persist for decades potentially centuries resistance degradation can harm organisms release toxic chemicals. There has been increasing interest developing methods removal from the environment, particularly water. Catalytic processes shown promise as potential method microplastic elimination, including biological methods, advanced oxidation processes, hydrolysis. This review article focuses on recent advances catalytic of microplastics water, various types catalysts applications. It also discusses be integrated into real-world water treatment systems microplastics. The highlights challenges opportunities associated with environment aims contribute development more effective sustainable addressing this issue. Future research should focus hybrid catalyst that combine strengths multiple improved efficiency effectiveness. Additionally, explore use natural materials may offer environmentally friendly options. Collaboration between scientists, engineers, policymakers, public will critical implementation these systems. elimination requires multifaceted approach, continued collaboration necessary develop protect health our communities.
