Microplastic pollution, an emerging pollution issue, has become a significant environmental concern globally due to its ubiquitous, persistent, complex, toxic, and ever-increasing nature. As multifaceted diverse suite of small plastic particles with different physicochemical properties associated matters such as absorbed chemicals microbes, future research on microplastics will need comprehensively consider their multidimensional attributes. Here, we introduce novel, conceptual framework the "microplastome", defined entirety various (<5 mm), found within sample overall toxicological impacts. novel concept, this paper aims emphasize call for collective quantification characterization more holistic understanding regarding differences, connections, effects in biotic abiotic ecosystem compartments. Deriving from lens, present our insights prospective trajectories characterization, risk assessment, source apportionment microplastics. We hope new paradigm can guide propel microplastic toward era contribute informed strategy combating important issue.

Microplastic mixtures are ubiquitously distributed in global ecosystems and include varying types. However, it remains unknown how microplastic diversity affects the biotic interactions of microbes. Here, we developed novel experiments 600 microcosms with ranging from 1 to 6 types examined ecological networks for microbial communities lake sediments after 2 months incubation at 15 20 °C. We found that generally enhanced complexity both temperatures, such as increasing network connectance reducing average path length. This phenomenon was further confirmed by strengthened species toward high except negative Interestingly, temperatures exaggerated effects on structures, resulting higher connectivity interactions. Consistently, using extinction simulations, temperature led more robust networks, their were additionally positively mediated presence biodegradable microplastics. Our findings provide first evidence could unexpectedly promote stability future warming amplify this effect.

Microplastic detection and remediation through efficient interfacial solar evaporation for immaculate water production

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Июль 19, 2024

Freshwater scarcity and microplastics (MPs) pollution are two concerning intertwined global challenges. In this work, we propose a "one stone kills birds" strategy by employing an interfacial solar evaporation platform (ISEP) combined with MPs adsorbent. This aims to produce clean water simultaneously enhance removal. Unlike traditional predecessors, our ISEP generates condensed free from contamination. Additionally, the photothermally driven separation process significantly improves removal performance. We observed ratio increase of up 5.5 times compared previously reported adsorbents. Thus, rationally-designed holds promising potential not only mitigate existing issue but also remediate in natural environments.

Effects of microplastics on soil carbon pool and terrestrial plant performance

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.

Do Added Microplastics, Native Soil Properties, and Prevailing Climatic Conditions Have Consequences for Carbon and Nitrogen Contents in Soil? A Global Data Synthesis of Pot and Greenhouse Studies

Microplastics threaten soil ecosystems, strongly influencing carbon (C) and nitrogen (N) contents. Interactions between microplastic properties climatic edaphic factors are poorly understood. We conducted a meta-analysis to assess the interactive effects of (type, shape, size, content), native (texture, pH, dissolved organic (DOC)) (precipitation temperature) on C N contents in soil. found that low-density polyethylene reduced total (TN) content, whereas biodegradable polylactic acid led decrease (SOC). Microplastic fragments especially depleted TN, reducing aggregate stability, increasing N-mineralization leaching, consequently C/N ratio. size affected outcomes; those <200 μm both TN SOC Mineralization-induced nutrient losses were greatest at 1 2.5% weight. Sandy soils suffered highest contamination-induced depletion. Alkaline showed depletion, suggesting high degradability. In low-DOC soils, contamination caused 2-fold greater depletion than with DOC. Sites precipitation temperature had conclusion, there complex interactions determining impacts health. always risks but severity depends characteristics, properties, conditions, potential exacerbation by greenhouse emission-induced climate change.

Microplastic pollution promotes soil respiration: A global‐scale meta‐analysis

Global Change Biology, Год журнала: 2024, Номер 30(7)

Опубликована: Июль 1, 2024

Abstract Microplastic (MP) pollution likely affects global soil carbon (C) dynamics, yet it remains uncertain how and to what extent MP influences respiration. Here, we report on a meta‐analysis determine the effects of microbiome CO 2 emission. We found that significantly increased contents organic C (SOC) (21%) dissolved (DOC) (12%), activity fluorescein diacetate hydrolase (FDAse) (10%), microbial biomass (17%), but led decrease in diversity (3%). In particular, increases components further promote emission (25%) from soil, with much higher effect MPs these emissions than biomass. The could be attributed opposite vs. diversity, as accumulation recruited some functionally important bacteria provided additional substrates for specific heterotrophic microorganisms, while inhibiting growth autotrophic taxa (e.g., Chloroflexi , Cyanobacteria ). This study reveals can increase by causing shifts microbiome. These results underscore potential importance plastic terrestrial fluxes, thus climate feedbacks.

Опубликована: Июль 20, 2024

This study shows the general exponential rise in microplastic accumulation agricultural soils, with fertilizer application speeding up this increase, and future predictions of concentrations. Utilizing data from Broadbalk winter wheat experiment at Rothamsted Research, UK, 1846 to 2022, Poisson regression models were applied counts under different soil treatments, including farmyard manure, inorganic fertilizers, control conditions. A mass conversion factor was obtain w/w relationship. Results indicated a significant annual increase concentrations across all fertilized soils showing notably higher rate. Our forecasts that, 50 100 years now, treated fertilizers are expected reach 168.9 mg kg−1 (95% CI: 60.32–473.09) 1159 200.49–6699.8) respectively, levels converging on those used many experiments. highlights urgent need for strategies mitigate pollution fields. The results also help choose predicted global change experiments, as well motivate further research explore mechanisms integration these insights into broader ecological guide sustainable practices environmental conservation.
