Catalysis Communications, Journal Year: 2023, Volume and Issue: 183, P. 106764 - 106764

Published: Sept. 15, 2023

This review focuses on recently proposed photocatalyst designs for maximizing the efficiency of photogenerated charge carriers to improve photocatalytic performance photocatalysts. These include doping with metal and non-metal ions, surface grafting, noble deposition, dye sensitization, heterostructure fabrication. In addition, this thoroughly examines all prominent parameters that can influence degradation Furthermore, summarizes energy-band structures photocatalysts are suitable both O2 reduction oxidation H2O molecules generate reactive oxygen species. Lastly, we discuss future trends in development environmental applications.

Food and human safety: the impact of microplastics

Critical Reviews in Food Science and Nutrition, Journal Year: 2022, Volume and Issue: 64(11), P. 3502 - 3521

Published: Oct. 17, 2022

Plastic waste pollution is one of the biggest problems in world today. The amount plastic environment continues to increase, and human exposure microplastic (MP) has become a reality. This subject attracted attention whole world. MP problem also been noticed by scientific community. term mostly used define synthetic material with high polymer content that can have size range from 0.1 5000 µm. paper aims characterize routes MP, its sources, identify food types contaminated plastics. review addresses current state knowledge on this type particles, particular emphasis their influence health. Adverse effects depend sources exposure. most common route believed be gastrointestinal tract. Sources include fish, shellfish, water as well tea, beer, wine, energy drinks, soft milk, salt, sugar, honey, poultry meat, fruits, vegetables. Studies shown particles PET, PE, PP, PS, PVC, PA, PC are frequently found food.

A systematic review on microplastic pollution in water, sediments, and organisms from 50 coastal lagoons across the globe

Environmental Pollution, Journal Year: 2022, Volume and Issue: 315, P. 120366 - 120366

Coastal lagoons are transitional environments between continental and marine aquatic systems. Globally, coastal of great ecological socioeconomic importance as providers valuable ecosystem services. However, these fragile subject to several human pressures, including pollution by microplastics (MPs). The aim this review was identify summarize advances in MP research across the world. We consider peer−reviewed publications on topic published English Spanish 2000 April 21, 2022, available Scopus Google Scholar. found 57 with data abundances their characteristics 50 from around world, 58% which have some environmental protection status. number type has increased significantly since 2019. Methodological differences amongst studies MPs were nevertheless a limiting factor for wide−ranging comparisons. Most (77%) conducted single compartments, integration limited, hampering current understanding dynamics such lagoons. more abundant highly populated shores watersheds, support intensive activities. On contrary, natural protected areas had lower MPs, mostly sediments organisms.

New insights in to the environmental behavior and ecological toxicity of microplastics

Journal of Hazardous Materials Advances, Journal Year: 2023, Volume and Issue: 10, P. 100298 - 100298

Published: April 19, 2023

Microplastics in the environment can absorb and interact with organic pollutants, altering their toxic effects making microplastics more difficult to treat. Previous reports have focused on source, distribution ecotoxicity of different environmental substrates. come from two main sources: (1) a significant direct input primary (2) secondary resulting fragmentation larger plastic materials. migrate through atmospheric, freshwater, marine terrestrial environments. To investigate, uniform methods for monitoring examining will be developed combined source tracking technologies research impact.

Microbial metabolism influences microplastic perturbation of dissolved organic matter in agricultural soils

Published: Jan. 1, 2024

Abstract An estimated 258 million tons of plastic enter the soil annually. Joining persistent types microplastic (MP), there will be an increasing demand for biodegradable plastics. There are still many unknowns about pollution by either type, and one large gap is fate composition dissolved organic matter (DOM) released from MPs as well how they interact with microbiomes in agricultural systems. In this study, polyethylene MPs, photoaged to different degrees, virgin polylactic acid were added at levels incubated 100 days address knowledge gap. We find that, upon MP addition, labile components low aromaticity degraded transformed, resulting increased oxidation degree, reduced molecular diversity, changed nitrogen sulfur contents DOM. Terephthalate, acetate, oxalate, L-lactate DOM 4-nitrophenol, propanoate, nitrate major molecules available microbiomes. The bacteria involved metabolism mainly concentrated Proteobacteria, Actinobacteriota, Bacteroidota, fungi Ascomycota Basidiomycota. Our study provides in-depth understanding microbial transformation its effects evolution soils.
