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.

This study investigates the effects of different land-use types (forest, arable land, and wetland) on key soil properties, microbial communities, nitrogen cycling in Lesser Khingan Mountains. The results revealed that forest (FL) wetland (WL) soils had significantly higher organic matter (SOM) content compared with land (AL), total phosphorus (TP) being highest FL available (AN) WL. In terms enzyme activity, AL WL showed reduced activities ammonia monooxygenase (AMO), β-D-glucosidase (β-G), β-cellobiosidase (CBH), while exhibiting increased N-acetyl-β-D-glucosaminidase (NAG) highlighting impact use dynamics. also exhibited diversity evenness AL. dominant bacterial phyla included Actinobacteriota, Proteobacteria, Acidobacteriota, Acidobacteriota most abundant Proteobacteria Network analysis complex connected network, simpler but more stable networks, suggesting influence community interactions. Regarding genes, AOA-amoA was AL, AOB-amoA enriched FL, reflecting oxidation. These findings highlight how affect structures, cycling, offering valuable insights for sustainable management.

The potential impacts of biodegradable and nonbiodegradable microplastics (MPs) on rhizosphere microbial nitrogen (N) transformation processes remain ambiguous. Here, we systematically investigated how (polybutylene succinate, PBS) MPs (polyethylene, PE) affect N by determining soil indicators typical Glycine max (soybean)-soil (i.e., red brown soils) systems. Our results show that altered pH dissolved organic carbon in MP/soil type-dependent manners. Notably, soybean growth displayed greater sensitivity to 1% (w/w) PBS MP exposure than since acidified the impeded nutrient uptake plants. In rhizosphere, negatively impacted community composition diversity, weakened (mainly denitrification ammonification), disrupted metabolism. Overall, it is suggested MPs, compared can more significantly influence ecological function plant-soil system.

Microplastics (MPs) and nanoplastics (NPs) pose significant threats to aquatic terrestrial ecosystems, disrupting nutrient cycling, altering soil properties, affecting microbial communities. MPs NPs bioaccumulate contribute global water cycle disruptions, intensifying the impact of climate change. Despite widespread use plastics, inadequate plastic waste management leads persistent environmental pollution. Toxic compounds are transported by NPs, food chains, cycles, overall ecosystem health. biogeochemistry, activity, greenhouse gas emissions nitrogen carbon cycles. One largest gaps in microplastic (MP) research today is lack standardized sampling analytical methods. This standardization significantly complicates comparison results across different studies. Multidisciplinary strict regulatory measures needed address MP review highlights critical need for mitigation methods maintain integrity suggests data analysis. It offers insights into distribution, best practices analysis, impacts interactions with biogeochemical processes. The Environmental Protection Agency has identified a improve identification nanoplastics. Particles smaller than 10 μm become increasingly difficult quantify using standard detection practices.
