Micro- and nanoplastics (MNPs) are attracting increasing attention due to their persistence potential ecological risks. This review critically summarizes the effects of photo-oxidation on physical, chemical, biological behaviors MNPs in aquatic terrestrial environments. The core this paper explores how photo-oxidation-induced surface property changes affect adsorption toward contaminants, stability mobility water porous media, as well transport pollutants such organic (OPs) heavy metals (HMs). It then reviews photochemical processes with coexisting constituents, highlighting critical factors affecting MNPs, contribution phototransformation other contaminants. distinct mechanism aged pointed out, terms toxicity organisms, biofilm formation, planktonic microbial growth, soil sediment community function. Furthermore, research gaps perspectives put forward, regarding underlying interaction mechanisms natural constituents under conditions, combined fate microbiological effect photoaged especially biotransformation pollutants.

Although pervasive microplastics (MPs) pollution in terrestrial ecosystems invites increasing concern, impact of MPs on soil microbial community assembly, and ecosystem functions multifunctionality received relatively little attention. Here, we manipulated a mesocosm experiment to investigate how polyethylene (PE MPs; 0, 1%, 5%, w/w) influence plant production, quality, diversity enzymology carbon (C), nitrogen (N) phosphorus (P) cycling, maize–soil continuum. Results showed that PE exerted negligible effect biomass (dry weight). The 5% caused declines the availability water, C P, whereas enhanced pH storage. activity C-cycling enzymes (α/β-1, 4-glucosidase, β-D-cellobiohydrolase) was promoted by 1% MPs, while β-1, 4-glucosidase inhibited MPs. reduced N-cycling (protease urease), increased P-cycling enzyme (alkaline phosphatase). shifted composition, number specialist species, stability networks resistance. altered with concentration decreasing dispersal limitation proportion (from 13.66 9.96%). Overall, improved concentration, α/β-1, urease, protease, ammonium-N content were most important predictors multifunctionality. These results underscore can alter assembly multifunctionality, thus development implement scalable solutions controlling become increasingly imperative sustainable agricultural production.

Microplastics (MPs), miniscule plastic particles measuring less than 5 mm in size, have become a concern terrestrial ecosystems, with primarily agricultural and wetland soils being the highest loadings. The adverse effect of MPs might lead to changes physicochemical biological characteristics soil including properties, microbial communities, plants, as well potential or affirmed correlations among them. Therefore, understanding risks effects MPs, particularly within soil-plant-microbe context is challenging subject substantial scientific inquiry. This comprehensive review focused on rhizosphere plant-microbe symbiotic relationships, implications for plant growth ecosystem-level nutrient fluxes. alter community composition, enzymatic activities rhizosphere, influencing availability uptake by plants. These can disrupt interactions, such mycorrhizal associations nitrogen-fixing symbioses, ultimately impacting cycling nutrients ecosystems. Furthermore, we elaborate relationships carrying Future research directions solutions microplastics menace acknowledging combined other contaminants, advanced technologies identification quantification, engineering remediation. knowledge MPs-induced impacts interactions essential generate mitigating actions environmental management conservation.

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.
