Microplastics (MPs) have attracted global concern because of their harmful effects on marine biota; toxic properties can negatively impact aquatic ecosystems. Fish is an essential source protein for humans, playing a crucial role in daily food intake. Until recently, MPs were addressed primarily as environmental pollutants, but they are now increasingly recognized contaminants the supply. The present review has comprehended current knowledge MP contamination freshwater and fishes Asia, including 112 peer-reviewed sources from 2016 to 2023. recorded 422 Asian (345 77 freshwater) be contaminated with MPs. Clarias gariepinus Selaroides leptolepi shown maximum environments respectively. Omnivorous carnivorous exhibited higher susceptibility ingesting Benthopelagic, demersal, reef-associated habitats identified more prone accumulation.

Low environmental impact remediation of microplastics: Visible-light photocatalytic degradation of PET microplastics using bio-inspired C,N-TiO2/SiO2 photocatalysts

Marine Pollution Bulletin, Journal Year: 2023, Volume and Issue: 193, P. 115206 - 115206

Microplastics (MPs) are plastic particles with sizes between 1 μm and 5 mm a ubiquitous presence in aquatic ecosystems. MPs harm marine life can cause severe health problems for humans. Advanced oxidation processes (AOPs) that involve the in-situ generation of highly oxidant hydroxyl radicals be an alternative to fight pollution. Of all AOPs, photocatalysis has been proven clean technology overcome microplastic This work proposes novel C,N-TiO2/SiO2 photocatalysts proper visible-active properties degrade polyethylene terephthalate (PET) MPs. Photocatalysis was performed aqueous medium at room temperature, evaluating influence two pH values (pH 6 8). The results demonstrated degradation PET by semiconductors is possible, achieving mass losses 9.35 16.22 %.

Assessing the Behavior of Microplastics in Fluvial Systems: Infiltration and Retention Dynamics in Streambed Sediments

Water Resources Research, Journal Year: 2024, Volume and Issue: 60(2)

Published: Feb. 1, 2024

Abstract Microplastics (MPs) have been detected ubiquitously in fluvial systems and advective transfer has proposed as a potential mechanism for the transport of (sub‐) pore‐scale MPs from surface waters into streambed sediments. However, influence particle sediment properties, well hydrodynamic flow regime, on infiltration behavior mobility sediments remains unclear. In this study, we conducted series flume experiments to investigate effect size (1–10 μm), type (fine coarse sand), regime (high/low flow) dynamics rippled streambed. Quantification particles compartments (surface flow, interface, streambed) was achieved using continuous fluorescence techniques. Results indicated that maximum depth decreased with increasing (11, 10, 7 cm 1, 3, 10 μm). The highest retardation observed fine experiment, where 22% were still at end experiment. Particle residence times shortest under high conditions, suggesting periods increased discharge can effectively flush This study provides novel insights complex MP retention contributes better understanding fate ecosystems. Quantitative data improve existing modeling frameworks assist assessing exposure risk ingestion by benthic organisms.

Abstract Background Antibiotics and microplastics are two major aquatic pollutants that have been associated to antibiotic resistance selection in the environment considered a risk human health. However, little is known about interaction of these at environmental concentrations response microbial communities plastisphere sub-lethal pollution. Here, we describe bacterial dynamics underlying this surface water bacteria community, resistome mobilome level using combination methods (next-generation sequencing qPCR), targets (16S rRNA gene, pre-clinical clinical class 1 integron cassettes metagenomes), technologies (short long read sequencing), assembly approaches (non-assembled reads, genome assembly, bacteriophage plasmid assembly).
