Abstract Soil, as a primary repository of plastic debris, faces an escalating influx microplastics. Microplastics have the potential to decrease soil bulk density and pH, well alter pore structure aggregation. These changes in physicochemical properties subsequently lead habitat degradation for microbes environmental shifts that impact plant growth. Masquerading carbon storage, microplastics can distort assessments pool by introducing plastic-carbon associated leachates, influencing organic matter (SOM) turnover through priming effects (e.g., dilution, substrate switching, co-metabolisms). Additionally, influence distribution particulate mineral-associated matter, consequently affecting accumulation stability carbon. Furthermore, also chemodiversity dissolved (DOM) soils increasing DOM aromaticity molecular weight while deepening its humification degree. The observed may be attributed inputs from microplastic-derived along with organo-organic organo-mineral interactions coupled microbial processes. Acting inert source carbon, create distinct ecological niche growth contribute necromass formation pathways. Conventional reduce contribution stable whereas bio-microplastics tend increase it. exert wide range on performance both internal external factors, seed germination, vegetative reproductive growth, inducing ecotoxicity genotoxicity. impacts arise alterations environment or uptake plants. Future research should aim elucidate storage within fractions, paying closer attention rhizosphere dynamics such stabilization mineral protection rhizodeposits soils. Graphical

Microplastics enhance the prevalence of antibiotic resistance genes in mariculture sediments by enriching host bacteria and promoting horizontal gene transfer

Eco-Environment & Health, Год журнала: 2025, Номер unknown, С. 100136 - 100136

Microplastics (MPs) and antibiotic resistance genes (ARGs) pose significant challenges to the One Health framework due their intricate multifaceted ecological environmental impacts. However, understanding of how MP properties influence ARG prevalence in mariculture sediments remains limited. Herein, polystyrene (PS) polyvinyl chloride (PVC) MPs with different sizes (20-120 μm 0.5-2.0 mm) were selected evaluate impacts underlying mechanisms driving ARGs dissemination. The results showed that PS PVC increased relative abundance by 1.41-2.50-fold 2.01-2.84-fold, respectively, compared control, particularly high-risk genes. polymer type effect was identified as more influential than size sediment resistome evolution. shifted microbial community assembly from stochastic deterministic processes, thus enriching host pathogens. Furthermore, highly hydrophobic not only recruited bacteria colonization but also facilitated exchange within plastisphere. exogenous additives released (e.g., heavy metals, bisphenol A, tridecyl ester) particles synergistically promoted conjugative transfer inducing oxidative stress enhancing cell membrane permeability. These findings revealed characteristics spread marine benthic ecosystems, underscoring importance mitigating pollution maintain ecosystem health, prevent zoonotic diseases, balance global health.

A critical review of the adsorption-desorption characteristics of antibiotics on microplastics and their combined toxic effects

Environmental Technology & Innovation, Год журнала: 2024, Номер 35, С. 103729 - 103729

Опубликована: Июнь 26, 2024

The interaction between microplastics (MPs) and pollutants is crucial for assessing the environmental risk of MPs. It necessary to pay attention adsorption/desorption behavior antibiotics on MPs due their potential role in antibiotic resistance. When MPs-loaded are ingested by organisms, they enter gastrointestinal tract undergo desorption, leading corresponding toxic effects. Existing literature primarily focuses adsorption behavior, while there a lack systematic generalizations desorption or combined effects organisms. Therefore, this article provides review mechanisms, biological tract. Desorption suggests that characteristics (aging hydrophobicity) components fluid (digestive enzyme species pH) can also have effect desorption. Moreover, summarizes induced MPs-antibiotics, demonstrating either enhance reduce plants, microorganisms, aquatic animals. Since methodological uniformity relevance natural environment main shortcomings existing literature, future research should focus actual water given region studying at gene, protein, metabolic levels. This direction expected provide valuable references insights evaluating antibiotics.

Опубликована: Фев. 7, 2025

The use of plastic agricultural mulching films presents a “double-edged sword”: while these enhance crop yields, they also lead to the accumulation film residues in soil, creating new pollutants (microplastics). Our understanding “plastisphere”, niche formed by where unique microbial communities and soil conditions converge remains limited. This is particularly true for protists, which are recognized as key determinants health. Therefore, this study simulated field experiment analyze effects long-term on structure protist rhizosphere, bulk plastisphere oilseed rape well their nutrients. results revealed that residual underwent significant structural chemical degradations. Protist diversity co-occurrence network complexity were markedly reduced soils. In addition, moisture content, inorganic nitrogen available phosphorus levels declined, leading deficiencies Functional shifts consumer protists phototrophs along with weakened interactions, have been identified drivers impaired nutrient turnover. underscores critical role maintaining cycling highlights profound adverse ecosystems. These findings provide valuable insights into mitigating residue preserve fertility ensure sustainable productivity.
