ClearUnraveling the effect of micro/nanoplastics on the occurrence and horizontal transfer of environmental antibiotic resistance genes: Advances, mechanisms and future prospects
This review examines how micro- and nanoplastics promote the spread of antibiotic resistance genes in the environment. The tiny plastic particles create conditions that help bacteria exchange resistance genes more easily by generating oxidative stress, making cell membranes more permeable, and providing surfaces where resistant bacteria can form communities. This is a growing public health concern because antibiotic-resistant infections are increasingly difficult to treat.
Microplastics in soils during the COVID-19 pandemic: Sources, migration and transformations, and remediation technologies
This review examines how the COVID-19 pandemic increased global plastic production by 5-10%, leading to more microplastic contamination in soils. The paper covers how microplastics enter soil, how they transform and migrate through it, and the remediation technologies available to address the problem. Understanding soil microplastic pollution matters because it can affect crops and ultimately enter the human food supply.
A Systematic Review and Global Trends on Blue Carbon and Sustainable Development: A Bibliometric Study from 2012 to 2023
This bibliometric review of blue carbon research from 2012 to 2023 found growing global interest in coastal carbon storage ecosystems like mangroves, seagrasses, and salt marshes for climate change mitigation. Despite their potential, blue carbon initiatives face significant challenges in contributing to Sustainable Development Goals, with only 15% of global targets met at the halfway point.
RepDwNet: Lightweight Deep Learning Model for Special Biological Blood Raman Spectra Analysis
Researchers developed a lightweight deep learning model called RepDwNet for analyzing Raman spectroscopy data from biological blood samples. The model achieved high accuracy while being small enough to run on portable spectrometer devices used in the field. The study demonstrates that advanced AI analysis of Raman spectra can be made practical for point-of-care and on-site testing applications without sacrificing analytical performance.
Ecosystem-specific composition and drivers of plastisphere resistome in freshwater and marine environments
This comparative meta-analysis of metagenomic data found that microplastics in freshwater and marine environments harbor distinct antibiotic resistance gene profiles, with freshwater plastispheres showing greater resistome diversity. Microplastics serve as hotspots for antibiotic resistance gene propagation, with mobile genetic elements facilitating transfer to potentially pathogenic bacteria.
Marine Intelligent Technology as a Strategic Tool for Sustainable Development: A Five-Year Systematic Analysis
This review surveys marine intelligent technology—including autonomous underwater vehicles, sensor networks, and AI-based monitoring systems—as strategic tools for sustainable ocean management, including microplastic detection and marine pollution surveillance.
Insight into effects of polyethylene microplastics in anaerobic digestion systems of waste activated sludge: Interactions of digestion performance, microbial communities and antibiotic resistance genes
Polyethylene microplastics in anaerobic digestion systems processing waste activated sludge increased hydrolysis efficiency at 1 mm particle sizes but also altered microbial community composition and enriched antibiotic resistance genes. The findings suggest that MPs in sludge management pose risks for spreading ARGs through land application of digested biosolids.
Insight into the responses of antibiotic resistance genes in microplastic biofilms to zinc oxide nanoparticles and zinc ions pressures in landfill leachate
Researchers examined how zinc oxide nanoparticles and heavy metals in landfill leachate influence antibiotic resistance genes (ARGs) in microplastic biofilms, finding that microplastic biofilms serve as enriched hotspots for ARGs under heavy metal selective pressure.
Optimization of Random Surface Scattering Models for RR Polarization in SoOp-R/GNSS-R Applications
This paper is not relevant to microplastics research; it develops new mathematical models to improve the accuracy of soil moisture retrieval from satellite-based GPS reflectometry (GNSS-R) polarization signals.
RepDwNet: Lightweight Deep Learning Model for Spectral blood Raman spectra classification
This paper is not about microplastics; it introduces RepDwNet, a lightweight deep learning model for classifying blood Raman spectra using portable spectrometers, combining multi-scale convolutions and residual connections for efficient spectral analysis.
Distinguishing removal and regrowth potential of antibiotic resistance genes and antibiotic resistant bacteria on microplastics and in leachate after chlorination or Fenton oxidation
Researchers compared chlorination and Fenton oxidation for removing antibiotic resistance genes and antibiotic resistant bacteria from microplastics and surrounding landfill leachate, finding that target ARGs on microplastics were reduced significantly less than those in leachate. The study also characterized regrowth potential after treatment, highlighting microplastics as persistent ARG reservoirs.
Legislation and Policy on Pollution Prevention and the Control of Marine Microplastics
This review analyses international legislation and policies targeting marine microplastic pollution, finding that most existing regulations focus narrowly on microbeads while failing to address other microplastic types, and identifies three systemic dilemmas that impede more comprehensive regulatory frameworks.
Mechanism of perfluorooctanoic acid on microplastic transport in Northeast farmland soils: Based on irrigation mode
Researchers found that perfluorooctanoic acid (PFOA) contamination in irrigation water influences microplastic migration through three types of agricultural soils, with high PFOA concentrations and biochar additions both inhibiting downward microplastic movement into deeper soil layers.
The Influence of the Big Five Personality Traits on Residents’ Plastic Reduction Attitudes in China
Researchers investigated how the Big Five personality traits (openness, conscientiousness, extraversion, agreeableness, neuroticism) influence Chinese residents' attitudes toward plastic reduction, finding that personality dimensions significantly shape individual support for or resistance to plastic-reduction behaviors.
Scientific Uncertainty of Marine Microplastic Pollution and the Dilemma of Future International Unified Legislation
This legal analysis reviews existing microplastic bans across countries and regions, finding that most only target microbeads in cosmetics rather than addressing the full range of microplastic sources, leaving significant regulatory gaps.
