Microplastic (MP) pollution has become a significant global concern in soil systems. The spatial risk of MPs soils, the cascading effects climate, human activities, and air quality, ecosystem gradients from natural habitats, agricultural lands, urban soils remain largely unknown. We compile comprehensive data set more than 3000 site-year field observations across agricultural, natural, ecosystems China. By using interpretable machine learning models statistical approaches, our findings reveal that approximately 4.32% China face potential ecological risks MPs, with being most vulnerable (e.g., 14.7% are at risk). Climate factors temperature precipitation), activities plastic film use), quality concentrations atmospheric particulate matter) have been identified as primary drivers MP risk. climate (p < 0.001) significantly impact soils. This work highlights urgent need for coordinated management to mitigate posed by especially lands.

The release of micro/nanoplastics (MNPs) from biodegradable plastics in gastrointestinal environments due to photoaging, along with their associated mechanisms and potential cytotoxicity, is largely unknown. Here, we show that poly(lactic acid)/poly(butylene adipate-co-terephthalate) (PLA/PBAT) films undergo ultraviolet resulting increased surface roughness a higher quantity MNPs on the surface. This aging process involves generation carbon- oxygen-centered free radicals, chain scission, formation oxidation products hydroxyl carbonyl groups. These can be released under water shear force, significantly increasing normalized mass loss aged approximately 0.128 mg/cm2 (18 times than unaged water). In environment, further increases about 0.196 (28 higher), likely enzymatic digestion ion-swelling effects. MNPs, primarily composed PLA, are smaller carry more negative charges conditions. THP-1 cell model, these affect viability dose-dependent manner. obtained through ultrafiltration, compared those collected via centrifugation, display broader size distribution induce pronounced toxicity cells, an EC50 243 mg/L. Preliminary comparative analysis indicates PLA/PBAT-derived present risks comparable to, or greater than, conventional plastic MNPs. findings underscore hazards plastics.

Plastic residues have emerged as a significant challenge in the environmental sector. Microplastics, which are plastic fragments smaller than 5 mm, ability to disperse through atmosphere, oceans, and land, posing serious threat human health by accumulating food chain. However, their minuscule size makes it difficult effectively remove them from environment using current technologies. This work provides comprehensive overview of recent advancements microplastic detection removal For methods, we discuss commonly used techniques such microscopic analysis, thermal mass spectrometry, spectroscopic energy spectrometry. We also emphasize importance integrating various analytical data-processing achieve efficient nondestructive microplastics. In terms strategies, explored innovative methods technologies for extracting microplastics environment.

Wetlands are one of the most crucial ecosystems for regulating carbon sequestration and mitigating global climate change. However, disturbance to dynamics caused by microplastics (MPs) in wetlands cannot be overlooked. This review explores impacts MPs on cycles within wetland ecosystems, focusing underlying physicochemical microbial mechanisms. The accumulation sediments can severely destabilize plant root functions, disrupting water, nutrient, oxygen transport, thereby reducing biomass development. Although may temporarily enhance storage, they ultimately accelerate mineralization organic carbon, leading increased atmospheric dioxide emissions undermining long-term sequestration. A critical aspect this process involves shifts community structures driven selective colonization MPs, which affect decomposition methane production, thus posing a threat greenhouse gas emissions. Notably, dissolved matter derived from biodegradable promote photoaging coexisting enhancing release harmful substances aged further impacting microbial-associated due disrupted metabolic activity. Therefore, it is imperative deepen our understanding adverse effects mechanisms health cycles. Future strategies should incorporate regulation ecological engineering techniques develop effective methodologies aimed at maintaining sustainable capacity affected MP contamination.
