Abstract Plant invasions pose a major threat to terrestrial biodiversity, and microplastic pollution in soil could exacerbate this problem. Seed germination, crucial stage for plants, can be affected by microplastics through both physical interference of plastic particles chemical leaching from additives. We conducted greenhouse experiment using native invasive plant species European grasslands, evaluated individual combined effects additives on germination parameters. found that primarily seed as agents, while these exerted comparatively lesser impact.

Study on Rapid Quantitative Detection of Soil MPs Based on Terahertz Time-Domain Spectroscopy

Analytical Chemistry, Journal Year: 2025, Volume and Issue: unknown

The presence of microplastics (MPs) in agricultural soils substantially affects the growth, reproduction, feeding, survival, and immunity levels soil biota. Therefore, it is crucial to investigate fast, effective, accurate techniques for detection MPs. This work explores integration terahertz time-domain spectroscopy (THz-TDS) with machine learning algorithms develop a method classification First, THz spectral image data were preprocessed using moving average (MA). Subsequently, three models developed, including random forest (RF), linear discriminant analysis, support vector (SVM). Notably, SVM model had an F1 score 0.9817, demonstrating its ability rapidly classify MPs samples. Three regression models, namely, principal component (PCR), RF, least squares (LSSVM), developed polymers soils. Six feature extraction methods used extract relevant parts containing key information. results study showed that accuracies PCR, LSSVM greater than 83%. Among them, RF highest overall accuracy.

The Individual and Combined Effects of Microplastics and Antibiotics on Soil Microbial Metabolic Limitation and Carbon Use Efficiency

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

ABSTRACT Microplastics and antibiotics are emerging pollutants that accumulate extensively in soils, both exerting adverse effects on soil ecosystems. The mechanisms underlying the combined of microplastics microbial metabolism remain insufficiently understood. Therefore, we evaluated individual different types (non‐degradable polyethylene biodegradable polylactic acid) an antibiotic (oxytetracycline) characteristics. Our results showed community was primarily limited by nitrogen under either or treatments; whereas it phosphorus treatments. All treatments, except for non‐biodegradable microplastic treatment, significantly alleviated carbon limitation ( p < 0.01), with effect being particularly pronounced treatments involving antibiotics. Notably, increased use efficiency 0.05). were influenced type their interaction antibiotics, highlighting complex nature these environmental pollutants. This study provided empirical basis understanding exposure co‐exposure to biodegradable/non‐biodegradable metabolism.

Microplastics (MP) are found to exist in various environmental media because of their small particle size, large quantity and difficult decomposition. Farmland soil is regarded as a major pool source MP. Inevitably, the chemical properties microbial community will be impacted when MP enters soil. Brassinolide (BR) has been shown an ameliorator adverse effect on development Pinellia ternata.

Published: March 16, 2025

Plastic contamination presents major environmental threats through its degradation into micro-sized particles that are harmful to a variety of organisms, including plants. Among terrestrial habitats, coastal dunes likely some the most plastic-polluted, but very few studies thus far have examined microplastic effects on wild plants native this habitat. Moreover, current research microplastics has limited relevancy due common use homogenously shaped un-weathered in exceeding concentrations. Our from biodegradable and non-biodegradable origin, their pristine (raw) weathered form, at concentration 106 per ml, plant Cutandia maritima. We first synthesized engineered high bulk plastic products. Then, we exposed C. maritima soil. While no effect was found following chronic exposure all types, reduced seed germination after mother plants, suggesting epigenetic modifications might an embryo stage. In contrast, direct microplastics, specifically polylactic acid, facilitated seeds germination. results highlight importance studying raise ongoing ecological consequences contamination, which should be taken account regulatory assessments.

With the extensive utilization of plastic products, microplastics/nanoplastics (MPs/NPs) contamination not only poses a global hazard to environment, but also induces new threat growth development and nutritional quality plantation agricultural products. This study thoroughly examines behavior MPs/NPs, including their sources, entry routes into plants, phytotoxicity under various biotic abiotic stresses (e.g., salinity, polycyclic aromatic hydrocarbons, heavy metals, antibiotics, plasticizers, nano oxide, naturally occurring organic macromolecular compounds, invasive Botrytis cinerea mycorrhizal fungi.) controlling strategies. MPs/NPs in systems mainly originate from mulch, sewage, compost fertilizer, municipal solid waste, pesticide packaging materials, etc. They enter plants through endocytosis, apoplast pathways, crack-entry modes, leaf stomata, affecting phenotypic, metabolic, enzymatic, genetic processes such as seed germination, metabolism, photosynthesis, oxidative stress antioxidant defenses, fruit yield nutrient quality, cytotoxicity genotoxicity. can interact with other environmental stressors, resulting synergistic, antagonistic, or neutral effects on phytotoxicity. To address these challenges, this review highlights strategies mitigate toxicity, novel green biodegradable plastics, plant extraction immobilization, exogenous regulator interventions, porous nanomaterial modulation, biocatalysis enzymatic degradation.
