Abstract

Cerium dioxide nanoparticles (CeO2-NPs) are increasingly used in various industrial applications, leading to their inevitable release into the environment including the soil ecosystem. In soil, CeO2-NPs are taken up by plants, translocated, and accumulated in plant tissues. Within plant tissues, CeO2-NPs have been shown to interfere with critical metabolic pathways, which may affect plant health and productivity. Moreover, their presence in soil can influence soil physico-chemical and biological properties, including microbial communities within the rhizosphere, where they can alter microbial physiology, diversity, and enzymatic activities. These interactions raise concerns about the potential disruption of plant-microbe symbiosis essential for plant nutrition and soil health. Despite these challenges, CeO2-NPs hold potential as tools for enhancing crop productivity and resilience to stress, such as drought or heavy metal contamination. However, understanding the balance between their beneficial and harmful effects is crucial for their safe application in agriculture. To date, the overall impact of CeO2-NPs on soil -plant system and the underlying mechanism remains unclear. Therefore, this review analyses the recent research findings to provide a comprehensive understanding of the fate of CeO2-NPs in soil-plant systems and the implications for soil health, plant growth, and agricultural productivity. As the current research is limited by inconsistent findings, often due to variations in experimental conditions, it is essential to study CeO2-NPs under more ecologically relevant settings. This review further emphasizes the need for future research to assess the long-term environmental impacts of CeO2-NPs in soil-plant systems and to develop guidelines for their responsible use in sustainable agriculture.

二氧化铈纳米颗粒对土壤-植物系统的影响及其潜在的农业应用
二氧化铈纳米颗粒(CeO2-NPs)越来越多地用于各种工业应用,导致其不可避免地释放到环境中,包括土壤生态系统。在土壤中,CeO2-NPs被植物吸收、转运并在植物组织中积累。在植物组织中,CeO2-NPs已被证明会干扰关键的代谢途径,从而可能影响植物的健康和生产力。此外,它们在土壤中的存在可以影响土壤的物理化学和生物特性,包括根际微生物群落,在那里它们可以改变微生物生理学、多样性和酶活性。这些相互作用引起了对植物营养和土壤健康所必需的植物-微生物共生的潜在破坏的关注。尽管存在这些挑战,CeO2-NPs仍有潜力作为提高作物生产力和抗逆性(如干旱或重金属污染)的工具。然而,了解它们的有益和有害影响之间的平衡对于它们在农业中的安全应用至关重要。迄今为止,CeO2-NPs对土壤-植物系统的总体影响及其潜在机制尚不清楚。因此,本文对最近的研究成果进行了分析,以全面了解土壤-植物系统中CeO2-NPs的命运及其对土壤健康、植物生长和农业生产力的影响。由于目前的研究受到不一致的结果的限制,通常是由于实验条件的变化,因此有必要在更生态相关的环境下研究CeO2-NPs。这篇综述进一步强调了未来的研究需要评估土壤-植物系统中CeO2-NPs的长期环境影响,并制定可持续农业中负责任地使用CeO2-NPs的准则。

期刊介绍: Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, will be preferred. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental or methodical details, or both, must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Nanomaterials is dedicated to a high scientific standard. All manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.
