Опубликована: Янв. 26, 2024

Abstract Microplastics are polymer-based materials with carbon as their main framework. During degradation, they release greenhouse gases such dioxide and methane. Additionally, environmental microplastics can enter plant tissues, triggering oxidative stress in cells, adversely affecting photosynthesis, metabolism, gene expression, other growth parameters. This reduction efficiency sequestering utilizing atmospheric indirectly impacts global cycling, exacerbating the effect. Furthermore, significantly alter soil structure composition of microbial communities, emissions dioxide, methane, nitrous oxide, thus promoting gas emissions. Increasing research suggests a mutual reinforcement between microplastic pollution climate warming, where exacerbates rise average temperature leads to resuspension sediments, intensifying environment. article primarily focuses on different ecosystems relationship warming. It summarizes effects marine, terrestrial, ecosystems, well mechanisms by which change affect ecosystem services. By delving into intricate connection emissions, this paper aims raise awareness caused calls for further change, ultimate goal protecting human health. Graphical

Wheat (Triticum aestivum L.) seedlings performance mainly affected by soil nitrate nitrogen under the stress of polyvinyl chloride microplastics

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Фев. 29, 2024

Abstract Microplastics are exotic pollutants and increasingly detected in soil, but it remains poorly understood how microplastics impact soil plant systematically. The present study was conducted to evaluate the effects of polyvinyl chloride (PVC-MPs) on wheat seedlings performance properties. Under stress PVC-MPs, no new substance functional groups were generated by X-ray diffraction fourier transform infrared spectroscopy analyses, whereas characteristic peaks affected PVC-MPs. Wheat shoot biomass nitrate nitrogen significantly inhibited Chlorophylls not significant Superoxide dismutase, catalase, peroxidase activities increased, while malondialdehyde proline contents decreased significantly. Redundancy analysis displayed that traits can be largely explained nitrogen. Our results indicate PVC-MPs have more influence structure than composition. Moreover, even though antioxidant enzyme improved respond severely impacted Besides, is main factor prone ensure root growth under

Microplastics and nanoplastics in soil: Sources, impacts, and solutions for soil health and environmental sustainability

Journal of Environmental Quality, Год журнала: 2024, Номер 53(6), С. 1048 - 1072

Опубликована: Сен. 8, 2024

Abstract The present review discusses the growing concern of microplastics (MPs) and nanoplastics (NPs) in soil, together with their sources, concentration, distribution, impact on soil microorganisms, human health, ecosystems. MPs NPs can enter through various pathways, such as agricultural activities, sewage sludge application, atmospheric deposition. Once they accumulate upper layers affect structure, water retention, nutrient availability. presence also have ecological consequences, acting carriers for pollutants contaminants, heavy metals persistent organic pollutants. Additionally, leaching chemicals additives from pose public health risks food web groundwater contamination. detection analyses be challenging, methods involve spectroscopic microscopy techniques, Fourier‐transform infrared spectroscopy scanning electron microscopy. To mitigate effects it is essential to reduce plastic waste production, improve management practices, adopt sustainable practices. Effective mitigation measures include implementing stricter regulations use, promoting biodegradable alternatives, enhancing recycling infrastructure. amendments, biochar compost, help immobilize NPs, reducing mobility bioavailability. This article aims provide a comprehensive understanding these emerging environmental issues identify potential solutions alleviate ecosystem functioning, community health.

Microplastics pose a serious ecological threat to agricultural soils, as they are very persistent in nature. can enter the soil system different ways and present shapes concentrations. However, little is known about how plants react microplastics with concentrations shapes. To this end, we conducted factorial pot experiment wheat (Triticum aestivum L.) which mixed polystyrene (PS) (bead, fiber powder) at of 0, 1, 3 5%. Although all PS significantly reduced morphological growth traits, powder shape was microplastic that plant height (by 58–60%), fresh biomass 54–55%) dry 61–62%) most, especially 3% 5% compared 0% PS. Similar negative effects were also observed for root length weight concentrations, regardless shape. A concentration-dependent reduction leaf area index (LAI) observed. Interestingly, increasing concentration tended up-regulate activity antioxidant enzymes shapes, indicating potential complexity highly time-dependent response related various reactive oxygen species (ROS). Importantly, caused significant chlorophyll pigmentation photosynthetic rate. For transpiration rate, stomatal conductance intercellular CO2 concentration, on increased increase Overall, concluded higher potentially more devastating physiological biochemical attributes wheat, evidenced by pigments gas exchange parameters We recommend further research experiments not only translocation but tissue-specific retention sizes crops fully understand their impact food safety.

Journal of Nanobiotechnology, Год журнала: 2025, Номер 23(1)

Опубликована: Март 21, 2025

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. Finally, identifies current limitations future research directions critical field.
