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.

The emergence of polyvinyl chloride (PVC) microplastics (MPs) as pollutants in agricultural soils is increasingly alarming, presenting significant toxic threats to soil ecosystems. Ajwain (Trachyspermum ammi L.), a plant medicinal and culinary value, subjected environmental stressors that threaten its growth productivity. This situation particularly acute given the well-documented toxicity chromium (Cr), which has been shown adversely affect biomass escalate risks productivity such economically therapeutically important species. present study was conducted investigate individual effects different levels PVC−MPs (0, 2, 4 mg L−1) Cr 150, 300 kg−1) on various aspects growth. Specifically, we examined biomass, photosynthetic pigments, gas exchange attributes, oxidative stress responses, antioxidant compound activity (both enzymatic nonenzymatic), gene expression, sugar content, nutritional status, organic acid exudation, accumulation parts L.) seedlings, were also exposed varying titanium dioxide (TiO2) nanoparticles (NPs) 25, 50 µg mL−1). Results from showed increasing significantly decreased sugars, contents roots shoots plants. Conversely, increased indicators term malondialdehyde, hydrogen peroxide, electrolyte leakage, exudation pattern T. seedlings. Interestingly, application TiO2−NPs counteracted leading greater biomass. protective effect facilitated by NPs' ability sequester reactive oxygen species, thereby reducing lowering concentrations both Our research findings indicated enhance resilience seedlings toxicity, not only improved but healthier physiological state demonstrated more balanced acids, critical response mechanism metal stress.

Although the influence of microplastics (MPs) in different soil environments has been investigated, their effects on physiochemical properties and chemical speciation heavy metals yellow-brown remains unknown. This study aimed to determine various concentrations linear low-density polyethylene (LLDPE), polyamide (PA), polyurethane (PU), polystyrene (PS), (LDPE) MPs environment cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn). influenced physicochemical soil. The can be altered by changing LDPE MP. relationship between changes field capacity (FC) was approximately linear. containing added PA, PU, were substantially improved (control vs. MPs): FC, 39 % 42.50 for cation exchange (CEC) 45.77, 56.65, 57.44 cmol.kg−1 respectively, organic matter (OM) content, 40.16 51.68 g.kg−1 PA. LLDPE PU also simultaneously affected increased acid-soluble (45.17–54.67 (Cd-F1), 7.24–11.30 (Cu-F1), 4.20–7.23 (Pb-F1), 21.21–31.47 (Zn-F1)) reducible (24.02–29.41 (Cd-F2), 25.69–34.95 (Cu-F2), 74.29–81.07 (Pb-F2), 28.77–34.19 (Zn-F2)) fractions metals, which bioavailability. However, reduced ecological risk increasing content residual fraction (26.11–40.21 (Cd-F4), 47.63–59.67 (Cu-F4), 17.25–26.76 (Pb-F4), 32.63–50.46 (Zn-F4)). Changes impact might change metals. requires further investigation.
