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.

Abstract Micro/nanoplastic (MNP) pollution in soil ecosystems has become a growing environmental concern globally. However, the comprehensive impacts of MNPs on health have not yet been explored. We conducted hierarchical meta‐analysis over 5000 observations from 228 articles to assess broad parameters (represented by 20 indicators relevant crop growth, animal health, greenhouse gas emissions, microbial diversity, and pollutant transfer) whether depended MNP properties. found that exposure significantly inhibited biomass germination, reduced earthworm growth survival rate. Under exposure, emissions gases (CO 2 , N O, CH 4 ) were increased. caused decrease bacteria diversity. Importantly, magnitude impact soil‐based was dependent dose size; however, there is no significant difference type (biodegradable conventional MNPs). Moreover, As uptake plants, but promoted plant Cd accumulation. Using an analytical hierarchy process, we quantified negative as mean value −10.2% (−17.5% −2.57%). Overall, this analysis provides new insights for assessing potential risks ecosystem functions.

Microplastic is globally regarded as an important factor impacting biogeochemical cycles, yet our understanding of such influences limited by the uncertainties intricate microbial processes. By multiomics analysis, coupled with soil chemodiversity characterization and carbon use efficiency (CUE), we investigated how responses to microplastics impacted cycling in a long-term field experiment. We showed that biodegradable promoted organic accrual average 2.47%, while nondegradable inhibited it 17.4%, consequence virus–bacteria coadaptations disturbance. In relevant functional pathways, significantly ( P < 0.05) enhanced abundance transcriptional activity related complex carbohydrate metabolism, whereas functions involved amino acid metabolism glycolysis. Accordingly, viral lysis treatments introduce more compounds dissolved matters, thus benefiting oligotrophs high metabolic capabilities exploitation competition. contrast, enriched auxiliary genes through “piggyback-the-winner” strategy, conferring dominant copiotrophs, substrate utilization capabilities. These virus–host interactions were also demonstrated corresponding plastisphere, which would alter resource allocation via CUE, affecting storage consequently. Overall, results underscore importance viral–host microplastics-dependent ecosystem.

Microplastics (MPs) pollution has become a global problem, potentially affecting soil carbon cycling and structure stability in agricultural systems. However, the effects of MPs on organic fractions/transformation aggregate remain unknown. Thus, combination one-year pot short-term mineralized incubation experiments that involved reference (CK, with no MPs), different concentrations (0.1, 1, 2 w/w % polyethylene (PE)), types (0.1 PE, polypropylene (PP), polyvinyl chloride (PVC)) were carried out to investigate mineralization after one year adding MPs. The results showed size distribution partial aggregates varied significantly as affected by MP concentration type (p ˂ 0.05). Compared 0.1% significant increases MWD (mean weight diameter) GMD (geometric mean 2% PE 27.22% 32.73%, respectively, detected. In addition, high (>1%) decreased dissolved (DOC) 0.05), whereas they increased stable fractions including particulate (POC) mineral-bound (MOC) 0.01).
